论文摘要
工作中介绍了对接端多电池矩阵比例计数器（MMPC）的构建。每个细胞是一个对接端比例计数器，其阴极直径为5 mm，圆形阳极直径为0.8 mm。在$ 3 \ times3 $矩阵的示例中，表明中央电池的气体繁殖取决于外围电池阳极处的电势，漂移电极，形成环和结构的周围金属部分。当MMPC填充96.3 \％AR + 3.7 \％Xe和90 \％AR + 10 \％CH $ _4 $的混合物时，测量了振幅特性，在620 Torr和62 Torr的压力下。该校准是用$α$ - 粒子和$γ$ - Quanta进行的，从$^{238} $ PU来源进行。对于能量为7.5 keV的光子，获得了26 \％的分辨率。结果表明，基于MMPC，可以制造任意配置的记录表面。
The construction of a butt-end multicell matrix proportional counter (MMPC) is presented in the work. Each cell is a butt-end proportional counter with a 5 mm cathode diameter and 0.8 mm circular anode diameter. In the example of the $3\times3$ matrix, it is shown that the gas multiplication of the central cell depends on the potentials at the anodes of the peripheral cells, the drift electrode, the forming rings, and the surrounding metal parts of the structure. The amplitude characteristics were measured when the MMPC was filled with mixtures of 96.3\% Ar + 3.7\% Xe and 90\% Ar + 10\% CH$_4$ at pressures of 620 Torr and 62 Torr. The calibration was carried out with $α$-particles and $γ$-quanta from a $^{238}$Pu source. For photons with energies of 7.5 keV, a resolution of 26\% was obtained. It is shown that, based on MMPC, it is possible to fabricate recording surfaces of arbitrary configuration.
