Summer Research and Outreach Fellow

Program Overview

We are currently accumulating research projects for Summer 2023. The application period is open from December 15th, 2022 – February 13th, 2023.

Particle astrophysics is the study of the fundamental properties of the most basic building blocks of nature, and their influence on the evolution of structure in the Universe. The questions being addressed in this field are considered, world-wide, to be among the most important in physics today. Led by many of the scientists who developed the renowned Sudbury Neutrino Observatory (SNO) that grew into SNOLAB in Sudbury, Ontario, and theorists progressing models from the fundamental properties of dark matter to the imprint of dark matter on cosmological scales, Canada and Queen’s University have become a world leader in this field.

In this optic, Queen’s University applied for and was granted a major award from the Canada First Research Excellence Fund (CFREF) to create the Arthur B. McDonald Canadian Astroparticle Physics Research Institute, or the McDonald Institute (hereafter MI). This award has enabled Queen’s University and partner institutions to significantly build on their capacity to deliver a world-leading scientific research program in particle astrophysics as well as related fields, such as geochemistry, chemistry, material science, and engineering, while engaging industry partners, students, and the public.

The work performed at SNO and SNOLAB has led to a number of prestigious awards for both the team and the Director (Dr. Arthur B. McDonald) including the recent co-shares of the Nobel Prize in Physics 2015 and the 2016 Breakthrough Prize. In recent years, there has been a dramatic increase in research intensity in the field of particle astrophysics. Queen’s University aspires for MI to maximize the scientific, innovative, and long-term economic output of SNOLAB by providing resources focused on the highest priority areas within the particle astrophysics community. MI will enable unprecedented opportunities to shape the development of particle astrophysics in Canada, promote scientific excellence, provide unparalleled training opportunities, and engage youth and the general public through targeted outreach programs. This engagement will also ensure a sustained influx of scientific and diverse talent to astroparticle physics and the broader sciences, maintaining Canada as a world-leader in astroparticle physics. The proposed summer position(s) sit within this focus of training and engagement of younger Canadians and early career researchers.

 

Significance of Project to Science, Society, and Queen's

The present generation of experiments are predicated on new theoretical models, and improvements in the fields of geochemistry, engineering, and material science, and their corresponding technologies. During the seven-year CFREF funding period several of these experiments are leading or will lead the world in sensitivity to weakly interacting particles. These experiments have the capability for the first direct observation of dark matter particles or neutrinoless double beta decay. The direct detection of dark matter particles could tell us the completely unknown nature of this form of matter that comprises 84% of the mass in our Universe. The observation of neutrinoless double beta decay can determine the neutrino mass and the nature of this fundamental particle, thereby contributing to an understanding of the creation of matter in the early Universe. Other constraints on dark matter come from improving theoretic models and their implications in astronomical and cosmological contexts. This area of physics is a top priority worldwide, and discoveries of this magnitude would sustain Canada as a global leader in this area of scientific research. Positioning and maintaining Canada as a leader in this area requires sustained support of science in the Canadian public, training of younger scientists, and exposure of astroparticle physics and science generally to young and aspiring researchers.

 

Job Description

Reporting to the Education & Outreach (E&O) Officer, each McDonald Institute Summer Research and Outreach Fellow (MI Fellow) will be responsible for both research, and research tools for training middle and high school students. 50% of the Fellow(s)’s time will be in progressing a research project of their choice with an MI faculty, with the intent to produce or contribute to a scientific paper. Their other 50% of time will be co-developing and implementing a summer school for a cohort of four-to-eight middle and high school students. The students in the cohort are the McDonald Institute Summer Scholars (MI Scholars). Each MI Fellow works with their research supervisor and E&O Officer to give the MI Scholars a hands-on introduction to science as a practice and profession, including skills training (computing, theory, experimental design, data entry, report writing), and a scaled-down, entry-level version of the research project the MI Fellow is pursuing. The summer would conclude with each of the MI Scholars presenting to the department and interested public on their work over the term of the summer camp. This would be followed by each MI Fellow presenting their research project to the department and interested public. By having multiple MI Fellows, as in past years, they each have a group of four-to-eight MI Scholars, and the groups focus on different science content. Further, more Fellows lead to more collaboration between them as they prepare their respective camp content, using their peers as a resource to facilitate their learning and growth. SWEP Fellows from past years in this role have said that the program was significantly more successful due to this peer learning opportunity.

 

Desired Qualifications:

The skills listed below are a wish list, thus we respect individuals will use this role as a way to develop these skills and demonstrate their growth throughout the job.

  • Must have completed at least one year of a physics, engineering physics, astronomy, computer science, mathematics, geology, or chemistry major. Alternatively, those pursuing an education degree could qualify with sufficient courses in some of the above sciences.
  • An interest in physics, astronomy, and science research, outreach, and/or education.
  • Strong written and oral communication skills.
  • Ability to work independently with strong skills in setting priorities and time management.
  • Ability to work as part of a team, work well with others, and accept guidance.
  • Serve as an ambassador in a manner that provides a positive reflection of the McDonald Institute’s vision, goals, and mission.
  • Capacity to mentor, assist, and support younger students.
  • Support efforts to advance equity, diversity, and inclusivity in a learning environment.
 

Learning Plan

Each MI Fellow will have the unique opportunity to experience research from a scientific pursuit, and a pedagogical lens through which they will be mentoring MI Scholars in what will likely be their first experience in research. This position also allows for clear impact on the Kingston community by sharing many of the skills developed above with an even younger generation. In addition to working with a team of world-leading physicists that includes the co-winner of the 2015 Nobel Prize for Physics, Dr. Arthur B. McDonald, the successful candidate may have the opportunity to visit exclusive research facilities such as SNOLAB during their stay with MI. They will be supported by an administrative team, will report to MI’s Education & Outreach Officer, and will have opportunities to meet with both MI’s Scientific Director, Dr. Tony Noble, and Director of External Relations, Edward Thomas. Finally, there would be financial support available to have the MI Fellow attend a conference to present their work, likely in the Fall or Winter.

 

Research Projects

Here we will list available research projects. This list will continue to be added to until January 13th.  Please indicate in your application which research project(s) (maximum of 2, ranked) you would like to pursue, and a small discussion of why it interests you.

BELOW IS A LIST OF 2022 PROJECTS AVAILABLE:

  1. Neutrons Mix & Match Game: Find the optimal combination of filters to create quasi-monoenergetic neutron beams in the 10 – 100 keV range, with Dr. L. Balogh: https://me.queensu.ca/People/Balogh/
    Related Topics: Material Science, Physics, Computer Simulations
    The Arthur B. McDonald Institute is building a source of quasi-monoenergetic neutron beams at the proton accelerator of the Kingston-based Reactor Materials Testing Laboratory (RMTL). The primary goal is to perform quenching factor measurements on Dark Matter detectors necessary for their calibration. The neutrons produced by the 7Li(p,n)7Be reaction have a relatively wide energy spectrum which needs to be narrowed. Many materials, such as Fe, Mn, etc., act as neutron filters as they selectively transmit neutrons of particular energies; though, usually substantial transmission happens at multiple energies. Thus, to obtain a quasi-monoenergetic neutron beam, it is necessary to use a combination of filters and/or tune the proton beam energy to modify the pre-filtered neutron spectrum. The goal of the project is to find an optimal combination of filter materials and accelerator settings to produce neutrons with the desired energy while minimizing their energy-spread and maximizing their flux. The work will involve setting up and using simulations, and may include participation at experiments performed at RMTL’s proton accelerator facility.
  2. Searching for Dark Matter Using Neutron Stars, with Dr. J. Bramante: https://www.physics.queensu.ca/facultysites/bramante/
    Related Topics: Physics, Astronomy, Theory
    Dark matter, even if it has very rare interactions with visible matter, can have dramatic effects on neutron stars. Through deposition of kinetic energy, dark matter can heat neutron stars, and very heavy dark matter can even cause neutron stars to collapse. This project will investigate the detection of dark matter using present and future observations of neutron stars.
  3. Searching for Dark Matter and Probing Stellar Origins with Interstellar Clouds, with Dr. Mike Chen: http://orca.phys.uvic.ca/~mcychen/
    Related Topics: Physics, Astronomy
    Dark matter is crucially important in shaping the Universe’s large-scale structures, and yet we know very little about its nature at the moment. While much of the current dark matter exploration is conducted with human-scaled detectors, which has their limits, our galaxy holds some of the most excellent dark matter detectors in nature: cold interstellar clouds. In this summer project, the SWEP student will model molecular line observations obtained with radio telescopes to determine gas temperatures in interstellar clouds. Such measurements will not only provide some of the first crucial pieces to probe dark matter heating in interstellar clouds, but they will also deliver critical information to understand the origin of stars in these clouds. The student will have the opportunity to work closely with Queen’s star formation group and apply physical modeling and statistical analysis using python software. The student will also learn communication skills to convey their research, a uniquely interdisciplinary study between star formation and dark matter search, and develop highly transferable problem-solving skills and an intuitive understanding of the astrophysical systems they are studying.
  4. How Low can we Go: Ultra-trace detection of background contamination for astroparticle physics using the triple quadrupole inductively coupled plasma mass spectrometer (ICP-MS), with Dr. M. Leybourne: https://mcdonaldinstitute.ca/matthew-leybourne/
    Related Topics: Geology, Physics
    This project will test the ability of the QQQ-ICP-MS to lower detection limits in routine applications in support of astroparticle physics experiments; this research will test the robustness of the instrumentation to deliver routine ultra-trace detection limits at abundance sensitivities that either rival those by AMS or that are sufficiently flexible to meet the varied and demanding needs of these astroparticle experiments. Previous work at SNOLAB has suggested that backgrounds on the order of sub-ppb (parts per billion) for 238U, 235U and 232Th and sub-ppt (parts per trillion) for some components are required, especially for U and Th decay products, with a need to push to much lower background levels for ultrarare events, such as the postulated 0νββ-decay. Other isotopes that can be present in deep-laboratories include 40K, 137Cs, 60Co, 54Mn, 7Be and some of the rare earth elements, and levels of these must also be monitored so that their impacts can be corrected for or ideally removed. The SWEP student would be involved with developing reaction gas methods to overcome spectral interferences in ICP-MS to permit ultra-trace detection limits. If there is time, we will also hyphenate a PrepFAST automated chromatography system to the new QQQ-ICP-MS to see if this combination can meaningfully lower detection limits even further.
    I anticipate that the SWEP student would also be involved with writing up some of the experimental work, and ultimately to be a co-author on a paper derived from the work. There will be several PhD and post-doctoral students working in the laboratory on similar projects, which will enhance the mentoring and EDI aspects of the work.
  5. Incorporating Dark Matter detector data into a Visitor Centre display, with Dr. T. Noble: https://www.queensu.ca/physics/aj-noble
    Related Topics: Physics, Education & Outreach, Engineering
    The student will work with the data and materials of the PICO (https://www.snolab.ca/experiment/pico/)and other particle detectors to construct exhibit pieces for the McDonald Institute Visitor Centre (https://mcdonaldinstitute.ca/science-education-astroparticle-physics/visitor-centre/). The exact project will need to be defined once the restrictions due to Covid during the summer are known. If there is access to the lab, one option already quite advanced is to complete the PICO exhibit. For this project some of the hardware has been developed to take real data from the PICO dark matter detector and present the images on a replica detector. However, the complete assembly of the various components into a final exhibit has not been completed due to lack of access. Another option is to work with the new light detection technology, silicon photo-multipliers, where the student would learn about the technology and its response and incorporate the data and technology into a visitor centre display. One exciting idea is to design and create an exhibit that would use these SiPm to track muon cosmic rays through the space in the visitor centre. The student would also develop these resources to be applicable to the summer camp program.
  6. Hunt for high-energy particle accelerators in the Universe with multi-messenger data, with Dr. N. Park: https://www.queensu.ca/physics/lemma
    Related Topics: Astronomy, Physics, Computer Science
    Recently a high-energy neutrino event triggered an intense campaign of follow-up observations across the electromagnetic spectrum, from radio up to gamma rays. The neutrino event was coming from the direction of a distant supermassive black hole classified as a blazar. Multi-messenger observations, the observations that combine information from many different particle messengers, are essential for us to study extremely powerful accelerators such as blazars existing in our Universe. In this project, the summer student will learn to understand neutrino and gamma-ray production from different astrophysical environments. The student will develop a multi-messenger database to collect and organize existing multi-messenger data.
  7. Let’s be real: adding imperfection to the detector simulation for HELIX, with Dr. N. Park: https://www.queensu.ca/physics/lemma
    Related Topics: Astronomy, Physics, Instrumentation, Computer Simulations
    A better understanding of propagation through our Galaxy is the key to understanding new features of the cosmic-ray flux (such as the unexpected excess of anti-matter) discovered by space-based experiments. HELIX is a long-duration balloon experiment designed to measure cosmic-ray isotopes to improve our understanding of the propagation of these particles. To achieve its scientific goals, HELIX needs to measure the trajectories and velocities of the particles very precisely. The summer student will add real-life imperfections, such as warped scintillator and aerogel surfaces, into the simulation model used to characterize the HELIX detector in order to evaluate the impact of realistic imperfections on the precision of the measurements.
  8. The effect of dark matter-electron interactions on stellar evolution, with Dr. A. Vincent: https://www.physics.queensu.ca/facultysites/vincent/
    Related Topics: Physics, Astronomy, Theory, Computer Science
    85% of the matter in the Universe is in the form of dark matter (DM), whose nature we do not understand. If dark matter can interact weakly with particles of ordinary matter, it can be detected in our underground laboratories, but may also have measurable effects on the structure and evolution of astronomical objects. While there are many ongoing searches for DM-nucleon interactions, a possibility is that DM only communicates via the leptonic sector, i.e. via electrons and neutrinos.  The goal of this project is to incorporate the possible particle physics interactions of DM with electrons into stellar simulations using MESA, and to determine if such interactions can affect the evolution of main sequence stars, and whether changes would be observable in the Sun or other stars via modifications of neutrino fluxes and asteroseismology.
    A strong programming background is recommended for this project. The core MESA program is written in high-performance Fortran on our supercomputing cluster (training will be provided). Data interpretation and analysis will use scripts built in Python, Matlab or a language of the student’s choice.
  9. Pursuing inorganic crystalline materials as radiation detectors, with Dr. P. Wang: http://queensucmcg.ca/team/cmcg-advisor/
    Related Topics: Chemistry, Education & Outreach, Material Science
    The advancement of many new technologies is empowered by the availability of specific inorganic crystalline compounds. In the field of astroparticle physics, single crystal materials are extensively used as detectors to study the interactions between cosmic radiation and matters. Our research focuses on the discovery and development of inorganic crystalline materials as radiation detectors. In addition to the technological and commercial values, inorganic crystals exhibit intrinsic, natural beauties stemming from their symmetry and optical properties. We are keen for a student with interest in visual arts who can take the research work and data and showcase it for the general audience.
  10. Analysis and Modelling of Astrometric Measurements from Gaia, Data Release 2, with Dr. L. Widrow: https://www.physics.queensu.ca/facultysites/widrow/
    Related Topics: Astronomy, Physics, Computer Science
    Gaia is a space telescope operated by the European Space Agency that is mapping the positions and velocities of over 1 billion stars in the Milky Way. The summer fellow will used Python-based tools to analyze data made public by ESA last summer with the aim of modelling the dynamics of the Galaxy’s stellar disk. The position may involve a mix of machine learning and numerical simulations.
