Dissertation Enhancement in Japan: Neutrino Astrophysics with the Super-Kamiokande Detector

9504114 Wilkes该论文增强奖支持华盛顿大学物理系研究生Andrew Stachyra在R. J. Wilkes教授的指导下进行为期6个月的日本研究访问。在日本停留的六个月里，斯塔奇拉将在三个不同的研究地点工作，期间他将得到东京宇宙射线研究所（ICRR）超级神冈组负责人土冢洋二（Yoji Totsuka）教授的资助。“超级神冈探测器”是一种水切伦科夫探测器，将被安置在日本的神冈莫见矿。“超级神冈”有望在中微子振荡研究、太阳模型、超新星模型以及设定核子衰变部分寿命的新限制方面提供新的有用信息。Stachyra先生将在ICRR大约花一个月的时间学习日本数据采集设备的工作原理，在KEK粒子加速器花两个月的时间学习正在那里用较小的切伦科夫探测器进行的校准实验并作出贡献，在1996年4月开始数据采集之前，将在矿区花大约三个月的时间学习探测器建造的细节。斯塔奇拉将学习日本建造高能物理实验用电子设备的方式，并将日本的系统与美国的系统进行比较。他将能够比较两种系统的优点和缺点，并了解哪一种比另一种更可取。＊＊＊

9504114 Wilkes This dissertation enhancement award supports a 6-month research visit in Japan for Andrew Stachyra, a graduate student in the Department of Physics at the University of Washington, who works under the direction of Professor R. J. Wilkes. Mr. Stachyra will divide his time among three different research sites over the course of his six month stay in Japan, during which he will be sponsored by the Professor Yoji Totsuka, the head of the Super-Kamiokande Group at the Institute for Cosmic Ray Research (ICRR) in Tokyo. Super-Kamiokande is a water Cherenkov detector to be located in the Kamioka Mozumi mine in Japan. Super Kamiokande is expected to provide new information that will be useful in the study of neutrino oscillations, in solar modeling, in supernova modeling, and in setting new limits on nucleon decay partial lifetimes. Mr. Stachyra will spend approximately one month at the ICRR learning how the Japanese data acquisition equipment works, two months at the KEK particle accelerator learning about and contributing to calibration experiments being conducted with a smaller Cherenkov detector there, and about three months will be spent at the mine site learning the details of detector construction before data taking begins in April of 1996. Mr. Stachyra will learn the Japanese style for constructing electronics for high energy physics experiments and will be able to compare the Japanese system with the U.S. system. He will be able to compare the advantages and drawbacks of both systems and learn when one is preferred over the other. ***
