Abstract
Using dc biases higher than those recommended by manufacturers, it is possible to exploit photoionization of excited atoms to obtain high sensitivities to uv radiation using gas-filled phototubes. Spectral response, nonlinearity of response, and dc bias effects are discussed. Comparisons are made with uv semiconductor detectors, and suggestions for future research are made. If a photocathode is used in a gas tube such devices are quite sensitive to both visible and uv radiation.
