我们描述了我们将玻璃毛细管板与对可见光敏感的光电阴极结合起来的努力，玻璃毛细管板在〜1atm下作为气体放大结构运行。这种毛细管是微通道板制造的副产品并且是可商购的。初步测试表明，无需光子反馈即可实现 >103 的气体增益。使用串联的两个毛细管板（双步乘法），在计数率 <100Hz/mm2 时，总增益可能高达 105。这种方法可能为气体探测器探测可见光子开辟新的可能性。潜在的优点是：增益高、敏感面积大、粒度高、对磁场不敏感。
We describe our efforts to combine glass capillary plates, operating as a gas amplification structure at ∼1atm, with photocathodes sensitive to visible light. Such capillary tubes are a by-product of the manufacture of Microchannel Plates and are commercially available. Preliminary tests indicate that gas gains >103could be achieved without photon feedback. With two capillary plates in tandem (double-step multiplication) overall gains up to 105were possible at counting rate <100Hz/mm2. This approach may open new possibilities for detection of visible photons by gaseous detectors. Potential advantages are: high gains, large sensitive area, high granularity, and insensitivity to magnetic fields.
