“…The JUNO project will use a 20 00 traditional dynode photomultiplier tube (PMT) or a 20 00 large area microchannel plate photomultiplier tube (MCP-PMT) [5,6]. They will be operated continually under high voltage during the entire data-taking period in JUNO, hence the degradation in performance of the PMT, including its gain, quantum efficiency (QE), linearity, collective efficiency (CE) and energy resolution.…”

“…Studies on the aging of proximity-focus MCP-PMTs [8][9][10] show that photocathode poisoning can be eased by using ion blocking film, stacking in a 'V' shape for two MCPs [11], stacking in a 'Z' shape for three MCPs, using vacuum transfer equipment, modifying the PMT structure [10] and improving the photocathode material. In this work, an aging experiment was performed on an 8 00 large area MCP-PMT, which was designed recently at Institute of High Energy Physics, Chinese Academy of Sciences [6].…”

The Institute of High Energy Physics, Chinese Academy of Sciences have designed a new type of photomultiplier tube (PMT) based on microchannel plates (MCPs) with large area photocathode, known as large area microchannel plate photomultiplier tube (MCP-PMT). The aging characteristics of the large area MCP-PMTs are different from dynode PMTs and small proximity-focus MCP-PMT. In this work, a prototype large area MCP-PMT was aged by operating with nearly 1000 photoelectrons per pulse for 3 months, and aging process of the MCP-PMT was discussed based on the aging curve.

The last angle of the PMNS mixing matrix has been measured by the neutrino reactor experiments. This important result opens the door to the precision era in the neutrino oscillation landscape. In this context, the next generation of reactor experiments at the kilo ton scale will significantly improve the measurements on the oscillation parameters and will give an answer on the mass hierarchy (MH) in the next decades. After a brief summary of the last results, these experiments will be presented with their technological challenges to reach the required sensitivity.

“…Researchers in the Institute of High Energy Physics (IHEP) have conceived a new concept of photomultiplier tube (PMT) for the next generation neutrino experiment in 2009 [1]. The small Micro-channel Plate (MCP) units replace the bulky Dynode chain in the traditional large PMTs, called as MCP-PMT.…”

For the next generation neutrino experiment, number of experienced researchers and engineers in research institutes and companies related to PMT fabrication in China jointly worked on the large area MCP-PMT collaboration group. In the past 5 years by collaborative work, the 8-inch and 20-inch prototypes were produced. And also get the high detection efficiency 20-inch MCP-PMT for JUNO in 2015, and get the 75% order of the JUNO-PMT. This manuscript will introduce the progress of the R&D of this new design of the MCP-PMT, also the performance tested result in the PMT Lab in IHEP.
