Paper Abstract

The soft X-ray quantum efficiencies of CsI and CsBr coated microchannel plates (MCPs) are described. These two materials are deposited on an MCP in quadrants. The quadrants are coated with CsI, CsBr, and a mixture of CsI and CsBr. The paper reports on the deposition techniques, background characteristics, imaging quality, and relative quantum efficiency over a selected range of X-ray energies from 0.1 KeV to 4.5 KeV.
