摘要:

对由两种不同等级的电木纸层压板制成的电阻板室(RPC)进行了比较研究,这些电木纸层压板在印度生产并可在市场上买到。在流光模式下使用氩气、四氟乙烷和异丁烷以34:59:7的混合比操作的腔室被测试用于宇宙射线的效率和稳定性。用于潮湿条件下高压绝缘的特定等级的酚醛树脂(P-120,NEMA LI-1989等级XXX)被发现具有令人满意的性能,连续超过130天的稳定效率> 96%。在酚醛RPC的内表面上的硅油的薄涂层被发现是必要的检测器的操作。

英文摘要:

A comparative study has been performed on Resistive Plate Chambers (RPC) made of two different grades of bakelite paper laminates, produced and commercially available in India. The chambers, operated in the streamer mode using argon, tetrafluroethane and isobutane in 34:59:7 mixing ratio, are tested for the efficiency and the stability with cosmic rays. A particular grade of bakelite (P-120, NEMA LI-1989 Grade XXX), used for high voltage insulation in humid conditions, was found to give satisfactory performance with stable efficiency of > 96% continuously for more than 130 days. A thin coating of silicone fluid on the inner surfaces of the bakelite RPC is found to be necessary for operation of the detector.
