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. © copyright owned by the author(s) under the terms of the creative commons attribution-noncommercial-noderivatives 4.0 international license (cc by-nc-nd 4.0).
