Abstract
A detector has been made using a guard-ring photodiode and a phosphor disk and the reproducibility and stability of the phosphor examined. The absolute quantum efficiency of the detector at wavelengths between 584 AA(0.65%) and 1216 AA(0.83%) has been obs. using a thermopile and a rare gas ionization chamber. The theory of a new mode of use of the ionization chamber is developed.Keywords
