Abstract

The design and performance of an image tube sensitive to ultraviolet radiation is described. The tube incorporates a standard vidicon gun section and is operated in a standard vidicon camera chain. The spectral response of the tube is determined by the choice of photocathode material and window. A tube having a CsI photocathode and a LiF window responds to radiation with wavelength between 1050 and 2000 Å. Other materials which vary the response within the spectral region 1050 to 3000 Å are discussed. Resolution, sensitivity, time constant, and quantum yield measurements of a laboratory model of the tube are discussed.
