WebNov 1, 2016 · In our work, a three-dimensional small area MCP model is developed in CST Studio Suite to evaluate the collection efficiencies of PMTs based on the traditional MCP and the coated one, respectively. Results predict that CE of the PMT based on the coated MCP has a significant increase and a better uniformity, which is expected to reach 100%. WebThe LEED 600 MCP has LEED and AES capabilities using a miniature electron gun, set of concentric grids and a conductive, phosphor coated screen. In addition, this optic model incorporates the high gain of microchannel plates. It is an extremely reliable high-performance LEED instrument which operates with up to date digital power supply.
A microchannel plate (MCP) is used to detect single particles (electrons, ions and neutrons ) and photons (ultraviolet radiation and X-rays). It is closely related to an electron multiplier, as both intensify single particles or photons by the multiplication of electrons via secondary emission, however because a microchannel plate detector has many separate channels, it can additionally p… WebMar 11, 2024 · This paper discusses the electron optical system of an 8-in. spherical MCP-PMT.
