Study of the Quantum Efficiency of CsI Photocathodes Exposed to Oxygen and Water Vapour

The operation of CsI photocathodes in gaseous detectors requires special attention to the purity of the applied gas mixtures.We have studied the influence of oxygen and water vapour contaminations on the performance of CsI photocathodes for theALICE HMPID RICH prototype. Measurements were done throu...
