【 摘 要 】

Hydrogen reduction process is an important process in the produce of microchannel plates (MCPs). The influence of hydrogen reduction temperature and time on the properties of lead silicate glass and MCPs were investigated by analyzing the spectral transmission, XRD, surface resistivity of the lead silicate glass and electron gain and bulk resistance of MCPs. Results show that the metal crystal of lead has been produced on the surface of glass after hydrogen reduction. With the increase of the reduction temperature or the reduction time, the transmittance and surface resistivity decreases. Meanwhile, the bulk resistance has the same changing trend. The best reduction temperature and time are available for the MCPs prepared by the lead silicate glass.
