来自Cherenkov辐射器的UV光子在低气压（40 Torr）下以门控模式操作的多级雪崩室中倍增。气体混合物为C2 H6-氩气（80 20）和TMAE，34° C。从单个光电子雪崩发射的可见光由耦合到图像增强器系统的CCD相机检测。用5GeV的c电子对探测器进行了测试，使用的是1atm的CH 4辐射体气体.切伦科夫环基本上没有粒子背景和二次光子反馈，在这种模式下获得的平均数n <$11.5（N 0 <$76 cm− 1）。我们提出了这种新的方法，并讨论其性能。
UV photons from a Cherenkov radiator are multiplied in a multistep avalanche chamber operating in a gated mode at low gas pressure (40 Torr). The gas mixture is C 2 H 6-argon (80 20) and TMAE at 34° C. Visible light emitted from single photoelectron avalanches is detected by a CCD camera coupled to an image intensifier system. The detector was tested with 5 GeV c electrons, using a CH 4 radiator gas at 1 atm. Cherenkov rings essentially free of particle background and of secondary photon feedback were obtained in this mode of operation with a mean number n≅ 11.5 (N 0≅ 76 cm− 1). We present this new method and discuss its performance.
