英文摘要	a novel large-area (20-inch) photomultiplier tube based on microchannel plate (mcp-pmts) is proposed for the jiangmen underground neutrino observatory (juno) experiment. its photoelectron collection efficiency c-e is limited by the mcp open area fraction (a(open)). this efficiency is studied as a function of the angular (theta), energy (e) distributions of electrons in the input charge cloud and the potential difference (u) between the pmt photocathode and the mcp input surface, considering secondary electron emission from the mcp input electrode. in cst studio suite, finite integral technique and monte carlo method are combined to investigate the dependence of c-e on theta, e and u. results predict that c-e can exceed a(open), and are applied to optimize the structure and operational parameters of the 20-inch mcp-pmt prototype. c-e of the optimized mcp-pmt is expected to reach 81.2%. finally, the reduction of the penetration depth of the mcp input electrode layer and the deposition of a high secondary electron yield material on the mcp are proposed to further optimize c-e.
