本工作测量了充氩和光致电离气体三乙胺的多丝正比室和多级雪崩室的特性,包括位置分辨曲线和输出脉冲幅度谱。低浓度三乙胺能有效地起猝灭作用。在三乙胺浓度很低时,实验观察到明显的雪崩横向扩展现象。
This work measures the characteristics of multi-wire proportional chamber and multi-stage avalanche chamber of argon and photoionization gas triethylamine, including the position resolution curve and the output pulse amplitude spectrum. Low concentrations of triethylamine can effectively quench effect. In the triethylamine concentration is low, the experiment observed significant avalanche lateral expansion phenomenon.
