Abstract
Singleé channel, multichannel and imaging types of UV detectors are reviewed. Solid-state detectors are still not well developed for UV work. Single-channel detectors such as vacuum photodiodes (PDs), photomultiplier tubes (PMTs), multichannel PMTs, and imaging detectors are used in the entire UV region. The spectral detective quantum efficiencies for the various detectors depend upon the types of cathodes and electron multipliers chosené, but peak DQEs are as high as 25 percent for PDs, 15 percent for PMTs, 15 percent for multichannel PMTs, and 15 percent for imaging detectors. Response times for these detectors range from impuélse response times of 15é0 ps FWHM for high-speed PMTs to the RS-170 video rate for IDs.
