摘要：

We report on the performance of 6 mum pore diameter Microchannel Plates (MCPs) fabricated in 50 x 50mm(2) format, from both standard and radio-isotope free low noise glass, by Photonis SAS for a European Space Agency Technology Research Programme. We compare them to MCPs manufactured by Photonis (the former Philips Photonics) for the High Resolution Camera (HRC) on NASA's Chandra X-ray observatory. The new MCPs represent a significant advance in MCP technology, having a much larger area than previously reported 6 mum plates, and demonstrating low noise 6 mum technology for the first time. The 6 mum plates are shown to be, mechanically, exceptionally well made with a defect density reduced by a factor of 2-5 compared to samples from the HRC flight blocks. They exhibit excellent gain and the expected 0.28keV (Carbon K) X-ray quantum efficiency. The low noise plates have a very uniform response to X-rays but the standard glass MCPs do show inhomogeneity on both the global and multifibre scales.
