Abstract

The characteristics of open Magnetic Electron Multipliers (MEM) with continuous dynode and field strips are discussed in view of their use in satellite-borne detection systems. Special emphasis is placed on selection, thermal stabilization, calibration, and long-time performance of the extreme ultraviolet detectors. Practical aspects of the design of satellite-borne detection systems, such as monitoring capabilities, immunity to charged particles, and electrical breakdown, are also described. Laboratory studies with fast electronics showed that the useful linear range of an MEM is restricted because of afterpulses. Most characteristics of MEM’s reported in the literature appear to be due to the use of relatively slow electronics that do not resolve the afterpulses. Statistical studies of afterpulses are reported, and a tentative explanation for the generation of afterpulses is outlined.
