摘要:

我们研究了基于气体电子倍增器(GEMs)的两相雪崩探测器的性能,并在Ar和Ar的电子雪崩模式下工作。研究了探测器的发射、增益、能量分辨率和稳定性等特性。相当高的增益,达到5000,和稳定的操作几个小时,观察到在两相氩雪崩探测器使用三GEM倍增器。成功地记录了X射线、β粒子和γ射线引起的信号。在两相雪崩探测器中得到了初步的结果:在两相雪崩和两相雪崩+2%CH_4中,三重GEM的最大增益约为200。所获得的结果在用于暗物质搜索、相干中微子散射、PET和数字射线照相的两相探测器领域中是相关的。

英文摘要:

We study the performance of two-phase avalanche detectors based on Gas Electron Multipliers (GEMs) and operated in an electron-avalanching mode in Ar and Xe. Emission, gain, energy resolution and stability characteristics of the detectors were studied. Rather high gains, reaching 5000, and stable operation for several hours were observed in the two-phase Ar avalanche detector using a triple-GEM multiplier. The signals induced by X-rays, beta-particles and gamma-rays were successfully recorded. Preliminary results were obtained in the two-phase Xe avalanche detector: the maximum gain of the triple-GEM in two-phase Xe and Xe+2%CH4 was about 200. The results obtained are relevant in the field of two-phase detectors for dark matter searches, coherent neutrino scattering, PET and digital radiography.
