Joint Study on Resistive Plate Chambers for the KEK B Detector

该项目的实施是为了确定计划于1998年在KEK b工厂建造的K_L-mu探测器的技术。日本的Tohoku、Tohoku- gakin、大阪市和KEK团体以及美国的弗吉尼亚理工大学和普林斯顿大学团体参与了这项合作工作。七名科学家被派往弗吉尼亚大学和普林斯顿大学，讨论和研究荷航探测器的电阻板室（RPC）。两名科学家被派往意大利帕维亚参加并在国际会议上介绍我们的RPC结果。通过这项工作，我们建立了；(1) RPC使用的材料为玻璃；(2)用氟利昂气体R116或134B代替目前没有的13b1；(3)在高湿气氛下进行RPC试验。RPC需要解决的其他问题是(1)长期稳定性和(2)费率依赖性，我们将在明年继续研究这些问题。

This project was carried out to established the technology for the K_L-mu detector scheduled to build in 1998 at KEK B-factory. Tohoku, Tohoku-Gakuin, Osaka City and KEK groups are participating to this Collaboration work from Japan and Virginia Technology and Princeton groups from USA.Seven scientists were sent to Virginia and Princeton University to discuss and investigate the resistive plate chambers (RPC) for the KLM detector. Two scientists were sent to Pavia in Italy to attend and present our RPC results at the Inteational Conference.Through this work, we have established ; (1)material to be used for RPC is glass, (2) Freon gas R116 or 134B will be used instead of 13 B1 which is unavailable now, and (3) RPC test in high humidity atmosphere.The other items to be solved for RPC are (1) long term stability and(2) rate dependence, We are proceeding to study these items in the coming year.
