摘要：
An improved model for microchannel platequantum efficiency and response at higher X-ray energies (up to 100's keV) is described, which builds on previous models by incorporating a more detailed consideration of photoelectron energies released in the MCP bulk. The contribution of multiple channel walls is included in the total response calculation. This model shows that MCP quantum efficiency and response decay as power law functions with energy, for photon energies > 140 keV. (C) 2012 Elsevier B.V. All rights reserved.
