Ultraviolet (UV) photomultipliers are key detectors in UV warning systems and communication. The UV microchannel plate photomultiplier tube (MCP-PMT) has the merits of high sensitivity, high gain, high resolution, low noise, small volume, and vibration resistance. However, the UV photomultiplier was invented too recently, and its technical performance is weak. Thus, further development and performance studies of the UV MCP-PMT has attracted increased attention. In this paper, a UV MCP-PMT using an end window structure is discussed. MgF2 and Cs2Te are used as the light window material and photocathode material, respectively. The UV MCP-PMT can detect the "day blind" UV band from 200 to 300 nm. A high-gain double channel plate structure is adopted. The device has a multiplication ability of approximately 5×106 under low voltage, thus improving the single photon detection capability of the UV MCP-PMT. This paper gives a brief introduction of the applications of UV MCP-PMT and the development of this type of photomultiplier in China and foreign countries. The test method of UV MCP-PMT is studied. The performance of the self-developed photomultiplier is evaluated, and the obtained data are analyzed. The results show that the MCP-PMT has high cathode radiation sensitivity with good response to single photons. Compared with the same type of products abroad, this design has the advantages of high gain, high peak valley ratio, and high resolution.
