我们已经调查了一个显着的样品的Hamamatsu H8500多阳极光电倍增管（MAPMT）作为单光子探测器的响应，鉴于他们使用的CLAS12光谱仪在托马斯杰斐逊国家加速器设施的环形成像切伦科夫计数器。为此，采用在407.2nm波长下工作的激光器。将样品平均分为标准窗口型（光谱响应在可见光区域）和UV增强窗口型MAPMT。研究证实了这些MAPMT在切伦科夫成像应用中用于单光子检测的适用性。
We have investigated the response of a significant sample of Hamamatsu H8500 MultiAnode PhotoMultiplier Tubes (MAPMTs) as single photon detectors, in view of their use in a ring imaging Cherenkov counter for the CLAS12 spectrometer at the Thomas Jefferson National Accelerator Facility. For this, a laser working at 407.2 nm wavelength was employed. The sample is divided equally into standard window type, with a spectral response in the visible light region, and UV-enhanced window type MAPMTs. The studies confirm the suitability of these MAPMTs for single photon detection in such a Cherenkov imaging application.
