DIRC 切伦科夫探测器将成为 FAIR PANDA 实验中 π/K 分离的主要设备。由于其在时间分辨率方面的优势特性，尤其是在磁场内部，微通道板光电倍增管 (MCP-PMT) 是非常有吸引力的传感器候选者。在本文中，我们对几种类型的多阳极 MCP-PMT 进行了研究。多像素 MCP-PMT 的暗计数率、高达 2T 磁场内的行为、时间分辨率、增益均匀性和串扰非常适合 PANDA 要求。即使 Burle-Photonis 和 Hamamatsu 的最新型号的速率能力也令人满意。尽管最近推出的 MCP-PMT 取得了巨大进步，但其寿命仍不足以满足 PANDA DIRC 预期的光子密度。
DIRC Cherenkov detectors will be the main devices for π/K separation at the PANDA experiment at FAIR. Due to their advantageous properties in terms of time resolution and especially inside magnetic fields micro-channel plate photo multipliers (MCP-PMTs) are very attractive sensor candidates. In this paper we present the investigation of several types of multi-anode MCP-PMTs. The darkcount rate, the behavior inside a magnetic field of up to 2T, the time resolution, the gain homogeneity and crosstalk of multi-pixel MCP-PMTs were found to be well suitable for the PANDA requirements. Even the rate capability of the latest models from Burle-Photonis and Hamamatsu is satisfactory. Although a big step forward was accomplished with these recently available MCP-PMTs, the lifetime is still not sufficient for the photon densities expected for the PANDA DIRCs.
