Dipartimento di Chimica Generale e Inorganica, Università di Roma “La Sapienza”, P. le A. Moro 2, 00185 Rome, Italy , Received 30 May 2006; revised 17 July 2007; accepted 6 August 2007. Available online 15 August 2007 Abstract The degradation of Cs. I thin film photocathodes (PCs) under Ultraviolet (UV) irradiation has been investigated by measuring the photocurrent as well as the absolute Quantum Efficiency (QE) as a function of the accumulated charge density. Atomic Force Microscopy (AFM) and UV Photoemission Electron Microscopy (PEEM) have been employed to study the surface morphology and the local QE of polycrystalline Cs. I thin films and their transformation due to UV irradiation. The photo-emissive properties of Cs. I PCs, together with their surface morphology, have been found to be strongly affected by the UV photon ageing. 10 th CBM Collaboration meeting at Dresden, Germany – V. Singh
