Winnipeg support for detector mechanics and electronics for subatomic physics experiments

点击翻译按钮获取中文摘要

The University of Winnipeg has four faculty doing research on subatomic physics experiments, including the Principal Investigator on the Ultracold neutron project (TUCAN) at TRIUMF. NSERC discovery grants are held by these faculty for research to measure the neutron electric dipole moment (J.W. Martin, R. Mammei, B. Jamieson, C. Bidinosti), measure the neutron decay asymmetry Nab (R. Mammei), and search for charge-parity violation of neutrinos with the T2K and Hyper-Kamiokande experiments (B. Jamieson). These are international collaborations, and this MRS would support these international projects that have strong leadership from Canadian researchers. D. Ostapchuk, MSc in physics, has unique set of skills in electronics development, cryogenics, design work, PCB layout and fabrication. Other examples of projects completed by Ostapchuk include: a 3 channel, 4th order low-pass active filter for flux-gates in an active magnetic shielding system; an 8th order band-pass active filter for fundamental noise lab to be used in 3rd year physics lab courses; schematic capture, circuit review, and final layout on a stripboard of a set of balanced photodiodes; programmable current sinks; breakout boards for hall effect sensors, autonomous obstacle-avoiding robots for digital electronics course, which included chassis design and fabrication using laser-cutting, electronics design, firmware development, and course material; electromagnetic shields for low-field NMR systems; and electromagnetic shielding and RF coil for the ultracold neutron simultaneous spin apparatus. This NSERC MRS resource will be advertised to the subatomic physics community at the Canadian Association of Physics Congress during the IPP and CINP annual general meetings, and the resource will be overseen by the allocation committee that is managing the University of Victoria and Carleton MRS. Initially D. Ostapchuck will continue projects related to Ultracold neutrons, and the Canadian neutrino-oscillation physics program based on proposals being prepared for the MRS board. It is expected that he will quickly be sought after by other Canadian projects that are developing their detectors for world leading research in subatomic physics, and should within a few years reach more than half of his time working on non-Winnipeg projects.
