We describe microchannel plate QVICP) detector systems that use wedge and strip anodes for imaging radiation in the range 50A to 8000Å. Test data, obtained from the calibration of the Extreme Ultraviolet Explorer Satellite (UVE)1 detectors and the AMA` EUV aeronomy sensor is presented. We have investigated the long term performance characteristics of Z stack microchannel plates and show that stable operation is achieved after an initial settling period. We discuss conventional and new anode designs and their potentiar increasing, the position resolution. Position resolution of better than 80 microns FWD has been attained for 50mm devices and is shown to be essentially independent of event location. Image nonlinearity of less than 0.3% has been achieved with stability to better than 0.1%. We demonstrate that differential nonlinearity of less than 1% and stability to better than 1% have been obtained. Measurements of the quantum efficiency of a CsI photocathode on an MCP are presented, demonstrating efficiencies as high as 47%.
