我们展示了对用于高压正比计数器的最佳气体混合物进行系统搜索的结果。使用各种淬火气体（以氩气或氙气作为主要填充气体）收集数据。气体增益和能量分辨率大致遵循气体体积内的复合电离。数据显示，氩气的光谱响应不会随压力发生显着变化。然而，对于氙来说，光谱响应主要由二次壳层相互作用过程和重组引起的电荷损失决定。
We present the results of a systematic search for the best gas mixture for use in proportional counters operating at high pressures. The data were gathered using a variety of quench gases with argon or xenon as the primary fill gas. The gas gain and the energy resolution broadly follow the complex ionization within the gas volume. The data show that the spectral response for argon does not change significantly with pressure. However, for xenon the spectral response is dominated by secondary shell interaction processes, and charge loss due to recombination.
