Abstract
In the framework of the CERN linear collider project (CLIC) the CLIC t est facility (CTF) uses a laser driven photocathode in an rf gun as an electron source. Photocathode properties are measured in the photoemi ssion laboratory, which contains a preparation chamber and a dc electr on gun, followed by a beam measurement line. Cathodes are illuminated by a nanosecond UV YAG laser. The present note concerns the present in stallation and summarises different photocathode tests on metallic as well as alkali cathodes. Those used in the rf gun of the CTF are parti cularly emphasized.
