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)首席研究员。这些教员持有NSERC发现补助金，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)，以及使用T2K和Hyper-Kamiokande实验(B.Jamieson)搜索中微子的电荷宇称破坏。这些都是国际合作，这一MRS将支持这些具有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套独特的技能。奥斯塔普丘克完成的其他项目包括：用于有源磁屏蔽系统中磁通门的3通道、4阶低通有源滤波器；用于基波噪声实验室的8阶带通有源滤波器，用于3年级物理实验室课程；原理图捕获、电路审查，以及在一组平衡的光电二极管的剥板上进行最终布局；可编程电流接收器；霍尔效应传感器的突破板，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，以及课程材料；低场核磁共振系统的电磁屏蔽；这个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界宣传，资源将由负责管理维多利亚大学的资源分配委员会和Carleton夫人监督，最初D.Ostapchuck将继续与超冷中子相关的项目，以及基于为MRS董事会准备的提案的加拿大中微子振荡物理项目。预计其他加拿大项目将很快追逐他，这些项目正在为亚原子物理领域的世界领先研究开发探测器。并在几年内达到他在非温尼伯项目工作的一半以上的时间。

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.
