摘要:

开发了一种用于多通道金属丝气体倍增器的电极的新颖且相对简单的生产方法。两个修改的乘法器已被测试:与倍增的电子之间的两个线电极,MWGEM,和之间的线电极和连续阳极,MWCAT。对于两个MWGEM和MWCAT探测器,充满氖的压力下的760托和β粒子(Ni-63)照射,电子的比例倍增系数高达10000。对于α粒子(Pu-239)辐照的MWGEM探测器,获得了300的比例倍增系数。据观察,在对比的GEM探测器,由穿孔的金属包覆的塑料箔,在MWGEM的放电不破坏它的电极,即使对于以上的电位放电的阈值。本文还介绍了充Ar、Ar+ CH_4和Ar+1%CH_4的MWCAT的运行结果。

英文摘要:

A novel and relatively simple method of production of electrodes for a multi-channel wire gas multiplier is developed. Two modifications of the multipliers have been tested: with a multiplication of electrons between two wire electrodes, MWGEM, and between a wire electrode and continuous anode, MWCAT. For both MWGEM and MWCAT detectors, filled with neon under pressure of 760 Torr and irradiated by beta-particles (Ni-63), the coefficient of proportional multiplication of electrons up to 10000 was obtained. For the MWGEM detector irradiated by alpha-particles (Pu-239), the coefficient of proportional multiplication of 300 was obtained. It is observed, that in contrast to the GEM detectors, produced by perforation of a metal-clad plastic foil, in a MWGEM the discharges do not destroy its electrodes even for the potentials above the threshold of discharges. The results on operation of the MWCAT filled with Ar, Ar+CH4 and Ar+1% Xe are also presented.
