测试了双相氙气室，以测量从液体提取到气体的电子的产量以及随后通过比例光进行的放大。研究了光输出作为电场和气压的函数。将紫外敏感的紧凑型金属通道光电倍增管放置在液氙上方的气体中，用于这些测量。通过对由初级闪烁光触发的电离信号的测量推断出电子寿命至少为 1.5 ms，并且同一室以单相运行。
A dual-phase xenon chamber was tested to measure the yield of electrons extracted from the liquid to the gas and their subsequent amplification via proportional light. The light yield was studied as a function of electric field and gas pressure. A UV-sensitive compact metal channel photomultiplier tube, placed in the gas above the liquid xenon, was used for these measurements. An electron lifetime of at least 1.5 ms was inferred from a measurement of the ionization signal, triggered by the primary scintillation light, with the same chamber operated in single phase.
