Abstract
A CuI coating on the first dynode of a windowless photomultipler creates a broadband and stable detector for ultraviolet plasma spectroscopy with a quantum efficiency above 2% from 400 to 1600 A. The stability of this photocathode was tested in the environment of tokamak discharges; no degradation was found after one year's use.Keywords
