Abstract

Microchannel plates (MCPs) have been used as imaging photon counters successfully in the extreme and far ultraviolet (EUV and FUV) for many years. Charge Coupled Devices (CCDs), on the other hand, have become established for low light level sensing at visible and near infrared wavelengths (as well as X-ray). Recently, CCDs have been proposed as EUV and FUV detectors. With proper thinning and backside (input) surface treatments, the CCD quantum efficiency in the EUV and FUV is comparable and sometimes exceeds MCPs. A comparison of MCPs and CCDs for use in EUV and FUV low light level imaging is presented including: quantum efficiency, spatial resolution, format size, dynamic range and long term stability. The current best measured results for each detector type are reviewed as well as their own unique problems and limitations. The low light sensitivities in the ultraviolet achievable with optimized detector systems of each type are compared quantitatively for both for space-based astronomical and spectroscopic applications.
