摘要:

我们研究了三重GEM(气体电子倍增器)检测器在纯稀有气体He和Kr在高压下,从1到15个大气压变化的性能。在这些气体中的操作进行比较,最近研究的Ne,Ar和氘。结果表明,轻稀有气体He和Ne具有优越的性能:最高增益,接近10^5,并且增益对压力的依赖性不寻常。特别是,在He和Ne中的最大增益不随压力而降低,与Ar,Kr和Ar相反。这些结果对于理解惰性气体中电子雪崩的基本机制以及在低温粒子探测器、X射线成像和中子探测器中的应用具有重要意义。

英文摘要:

We study the performance of the triple GEM (Gas Electron Multiplier) detector in pure noble gases He and Kr at high pressures, varying from 1 to 15 atm. The operation in these gases is compared to that recently studied in Ne, Ar and Xe. It turned out that light noble gases, He and Ne, have superior performance: the highest gain, approaching 10^5, and an unusual gain dependence on pressure. In particular, the maximum gain in He and Ne does not decrease with pressure, in contrast to Ar, Kr and Xe. These results are of high relevance for understanding basic mechanisms of electron avalanching in noble gases and for applications in cryogenic particle detectors, X-ray imaging and neutron detectors.
