Winnipeg support for detector mechanics and electronics for subatomic physics experiments

温尼伯大学有四名教师从事亚原子物理实验研究，包括TRIUMF超冷中子项目（TUCAN）的首席研究员。 NSERC发现赠款由这些教师持有，用于测量中子电偶极矩（J.W.马丁河妈妈，B。贾米森角Bidinosti），测量中子衰变不对称性Nab（R。Mammei），并利用T2 K和Hyper-Kamiokande实验寻找中微子的电荷宇称破坏（B. Jamieson）。 这些都是国际合作，这MRS将支持这些国际项目，有来自加拿大研究人员的强有力的领导。D. Ostapchuk，物理学硕士，在电子开发，低温，设计工作，PCB布局和制造方面拥有独特的技能。 Ostapchuk完成的项目的其他例子包括：一个3通道，4阶低通有源滤波器的磁通门在主动磁屏蔽系统;一个8阶带通有源滤波器的基本噪声实验室将用于第三年的物理实验室课程;原理图捕获，电路审查，并在一组平衡光电二极管的带状板上的最终布局;可编程电流吸收器;霍尔效应传感器的分线板、数字电子学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、电子学设计、固件开发和课程材料;低场NMR系统的电磁屏蔽;以及超冷中子同步自旋装置的电磁屏蔽和RF线圈。 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做广告，该资源将由管理维多利亚大学和卡尔顿MRS的分配委员会监督。Ostapchuck将继续开展与超冷中子有关的项目，并根据为MRS委员会准备的建议开展加拿大中微子振荡物理方案。 预计他将很快受到其他加拿大项目的追捧，这些项目正在为亚原子物理学的世界领先研究开发探测器，并应在几年内将一半以上的时间用于非温尼伯项目。

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.
