为满足大型高空风淋台（LHAASO）电磁探测器光电倍增管（PMT）测试的需要，研制了一种带二维扫描系统的多功能光电倍增管试验台。使用该二维扫描系统，可以同时扫描16个pmt进行特性测试，包括均匀性，阴极透射时间差，单光电子能谱，增益与高压，线性行为和暗噪声。试验台硬件可编程，软件智能化，使用方便，测试结果可靠。详细介绍了试验方法，并给出了初步结果。
To fulfill the requirements for testing the photomultiplier tubes (PMTs) of the electromagnetic detector at the Large High Altitude Air Shower Observatory (LHAASO), a multi-functional PMT test bench with a two-dimensional scanning system has been developed. With this 2D scanning system, 16 PMTs can be scanned simultaneously for characteristics tests, including uniformity, cathode transit time difference, single photo-electron spectrum, gain vs. high voltage, linear behavior and dark noise. The programmable hardware and intelligent software of the test bench make it convenient to use and provide reliable results. The test methods are described in detail and primary results are presented.
