Abstract
Image intensifiers are currently the primary detectors for ground-based optical astronomy. They are used with photographic emulsions and various electronic readout systems. They offer the advantages of reasonably high quantum efficiency, essentially noise-free amplification to very high gain values, and suitability for rapid readout. Progress in the development of a proximity intensifier for astronomy is very encouraging. A few samples have been produced that exhibit good blue response, resolution, gain, dark emission (when cooled), and freedom from field emission. However, the manufacturing yield of such samples is still low. An important step is to discover and eliminate the cause of lost-counting efficiency, observed in several diode intensifiers.
