Photometric detectors
Abstract
Two classes of detector, used in astronomical experiments, are described. These are: (1) photomultipliers and electron multiplier tubes for spectrometers and (2) image dissectors and image intensifiers for cameras. The structure and functional principles of these devices are explained. For the multipliers, spectral response (quantum yield), dark current, electronic gain, and amplitude distribution are given. Utilization of the anodic signals is specified. Particular characteristics that distinguish image dissectors from photomultipliers are pointed out. Besides technical characteristics, use of image intensifier output signal is treated. The analog method and the photon counting method are summed up.
