项目摘要

A Japanese group, participating in an international joint experiment ATLAS using LHC currently built in CERN, takes charge of a detector Thin Gap Chamber (TGC). The purpose of this research is to prove the high voltage power supply utilizing a piezoelectric ceramic transformer suits the high voltage power supply of TGC.TGC, using a number of high voltage power supplies, needs the multi-channel high-voltage power supply system that mounts a lot of high voltage power supplies in a compact size. So it is important to decrease the volume of the high-voltage power supply, and to raise the number of channels per volume. Sixty channels of the high-voltage power supplies have been successfully installed into the crate of 2U in height suited to 19-inch racks. Two high-voltage power supply systems were manufactured in 2004 fiscal year.The high-voltage power supply system was irradiated to gamma rays with cobalt 60 and to protons at PSI in Switzerland, by which radiation hardness of this power su … More pply was measured. As a result, it was proven that the high voltage power supply system satisfies the criteria for radiation hardness provided by CERNThis high-voltage power supply system has supported the functions that are needed by TGC. The system meets the requirements requested when the system is actually integrated into the apparatus of the experiment. We could have bid against CAEN for the high voltage power supply system of TGC if specifications of the tender do not claim that a high voltage power supply system shares the common crate with low voltage power suppliesThis high-voltage power supply system is connected to a computer with a USB cable. The control program of the system is available for Windows and Linux.This high-voltage power supply system has been taken note of by CERN people at the electronic section. The evaluation to examine whether the system can be adopted in CERN is in progress. Moreover, the joint development of the high-voltage power supply system is now proposed Less

利用欧洲核子研究中心（CERN）的大型强子对撞机（LHC）进行国际联合实验ATLAS的日本研究组负责了探测器薄间隙室（TGC）。本研究的目的是为了证明压电陶瓷变压器的高压电源适合TGC的高压电源。TGC使用多个高压电源，需要在一个紧凑的体积内安装大量高压电源的多通道高压电源系统。因此减小高压电源的体积，提高每体积的通道数是非常重要的。60路高压电源已成功安装在高度为2U、适合19英寸机架的板条箱中。2004财政年度制造了两个高压电源系统。将高压电源系统用钴60照射到伽马射线和瑞士PSI的质子上，测量了该电源系统的辐射硬度。结果表明，该高压供电系统满足cern提供的辐射硬度标准，支持TGC所需的功能。该系统能够满足实际集成到实验设备中的要求。如果标书中没有规定高压供电系统与低压供电系统共用一个箱，我们可以与CAEN竞争TGC高压供电系统。高压供电系统通过USB电缆连接到计算机上。本系统的控制程序支持Windows和Linux操作系统。这种高压供电系统已经被欧洲核子研究中心电子部的工作人员注意到了。该系统是否可以在CERN采用的评估正在进行中。此外，目前提出的高压供电系统的联合开发较少
