Winnipeg support for detector mechanics and electronics for subatomic physics experiments

温尼伯大学有四名教员从事亚原子物理实验的研究，其中包括TRIUMF的超冷中子项目(Tucan)的首席研究员。NSERC的发现基金由这些教师持有，用于研究测量中子电偶极矩(J.W.Martin，R.Mammei，B.Jamieson，C.Bidinosti)，测量中子衰变不对称性NAB(R.Mammei)，以及通过T2K和Hyper-Kamiokande实验搜索中微子的电荷宇称破坏(B.Jamieson)。这些都是国际合作，而这项MRS将支持这些得到加拿大研究人员强有力领导的国际项目。 奥斯塔普丘克，物理学硕士，在电子开发、低温、设计工作、印刷电路板布局和制造方面拥有一整套独特的技能。奥斯塔普丘克完成的其他项目包括：用于主动磁屏蔽系统中磁通门的3通道、4阶低通有源滤波器；用于三年级物理实验室课程的基波噪声实验室的8阶带通有源滤波器；一组平衡光电二极管的原理图捕获、电路审查和最终布局；可编程电流接收器；用于霍尔效应传感器的分路板；用于数字电子课程的自主避障机器人，其中包括使用激光切割的底盘设计和制造、电子设计、固件开发和课程材料；用于低场核磁共振系统的电磁屏蔽；超冷中子同时自旋装置的电磁屏蔽和射频线圈。 这一NSERC MRS资源将在IPP和CINP年度大会期间在加拿大物理协会大会上向亚原子物理学社区宣传，该资源将由管理维多利亚大学和Carleton夫人的分配委员会监督，初始D.Ostapchuck将继续与超冷中子相关的项目，以及加拿大中微子振荡物理计划，该计划基于正在为MRS董事会准备的提案。预计他很快就会受到加拿大其他项目的追捧，这些项目正在为世界领先的亚原子物理研究开发探测器，几年内他应该会有超过一半的时间在非温尼伯项目上工作。

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.
