A CsI-coated microchannel plate (MCP) is widely used for space missions in the spectral range of extreme ultraviolet (EUV), because of its high quantum efficiency. Although the CsI-coated MCP shows higher efficiency than bare ones, the degradation by deliquescence with the atmospheric water is known to be a serious problem. In this paper, we report the results of the experiment about stability of the CsI-coated MCP. The results show; 1) No abrupt decrease of the quantum efficiency (QE) of the CsI-coated MCP through the changes of storage environment was found. 2) The QE can be kept with decrease less than 10% by storing under H2O atmosphere at less than 0.05 Pa・hours.
