Summer 2018 job posting
Job number TR18-2-17
Position Title:Simulations and experiment development for the TRIUMF UCN source and the neutron EDM project
Name of Project:Simulations and experiment development for the TRIUMF UCN source and the neutron EDM project
Overview:Knowledge of fundamental properties of the neutron helps to understand many aspects of the universe. It all starts right after the Big Bang: matter wins over antimatter in the universe, making our existence possible. One essential ingredient for this matter-antimatter asymmetry is violation of a more fundamental symmetry, called CP violation. This, in turn might show up in a non-zero electric dipole moment (EDM) of the neutron, making EDM measurements the flagship of fundamental neutron physics.
About 100 s after the Big Bang, the relevance of the neutron properties continues: neutron beta-decay lifetime plays an important role in primordial nucleosynthesis, influencing, e.g., the helium abundance in the Universe significantly. If neutron lifetime results are combined with experiments determining other decay parameters of the neutron, important coupling constants of the weak interaction of fundamental particles can be determined.These are important for our understanding of solar models and tests of the Standard Model of particle physics.
Owing to its neutrality and long lifetime of around 15 min, one can also look very carefully at the gravitational interaction of neutrons, thus probing the quantum mechanical features of the gravity potential; in turn, this puts constraints on non-Newtonian gravity models.
All the experiments above have in common the need for very slow neutrons, called ultra-cold neutrons (UCN). We are presently building the UCN facility, all major installations are done and we're persuing first UCN production by the end of 2017. Opportunities exist for an undergraduate student to contribute in a significant way to the electric dipole moment experiment or the UCN facility start-up.
Duties:The student will work on simulations of ultracold neutrons in magnetic and electric fields and on the design of the high-voltage cell for the neutron EDM experiment. This work will be carried out in a team environment with physicists and graduate students from TRIUMF and the Universities of British Columbia (UBC), Winnipeg (UW), Manitoba (UM), Osaka (RCNP) and Tokio (KEK).
Skills learned during this work experience:For the particle simulation tasks the student will get familiar with Monte Carlo methods and particle spin-tracking. During the experimental and design tasks skills learned will be related to vacuum techniques, high-voltage and neutron depolarization requirements for the neutron EDM experiment.
Additionally, participation in our weekly international status meetings for the UCN source and EDM experiment is highly recommended for the student to get introduced into the international collaboration.
We are providing a stimulating environment for students to learn new things while contributing significantly to the progress of the project.
Qualifications:Third or Fourth year physics, engineering (Eng.Phys.) or electronics and mechanical engineering students with some experimental experience. Experience using CAD software (ideally SolidWorks) is recommended. Some experience using FEA software (e.g. ANSYS, Opera, FEMM) and C++ (or equivalent) and working in a linux-based environment would be advantageous for the simulation work.
Affinity for experimental techniques and development is what we are looking for in an ideal candidate.
Period of work:May-August 2018 with possible 4-month extension
Jobs are open to all qualified undergraduate students. |
Due to the volume of applications we receive, the TRIUMF Job Number must be clearly indicated on the application.
Applications must include:
A separate application must be submitted for each job the student wishes to be considered for.
Students should apply through their co-op office, where applicable, with the co-op office forwarding on their applications to TRIUMF. For those students not in a co-op program, applications (one PDF document for each job) may be sent directly to TRIUMF to firstname.lastname@example.org
Paper copies mailed to TRIUMF will be accepted as well, but email is the preferred method.
Salary is commensurate with academic progress and previous relevant work experience, and ranges from $ 1810 to $ 2710 per month plus 4% vacation pay. TRIUMF pays round-trip airfare (this does not apply to Vancouver/Victoria students); for Vancouver Island students, TRIUMF will pay ferry costs.
TRIUMF is an equal opportunity employer committed to diversity in the workplace, and we welcome applications from all qualified undergraduate students as defined below:
TRIUMF is located on the campus of the University of British Columbia. For more information, visit our web site http://www.triumf.ca
