Abstract

The relative quantum efficiency of several CsI photocathodes in an asymmetric multiwire proportional chamber has been measured. The photocathode surface of 24 x 24 cm² is divided into 7.5 x 7.5 mm² pads and the chamber is operated with methane at normal temperature and pressure and a gas gain of about 10⁵. During tests of the high rate performance (∼2 MHz/cm²) of a smaller chamber (5 x 5 cm²), an interesting time variation of the count rate has been observed when illuminating the chamber with constant UV light.
