Abstract

The ALICE/HMPID detector has been equipped with 42 large area CsI photocathodes providing a total of 11m2 of photosensitive area for the detection of Cherenkov light. This production summary reports on the CsI coating procedure and provides results of the quality monitoring measurements by means of a photocurrent scanner system. The importance of the heat enhancement of CsI PCs is stressed and difficulties due to variations in this process are presented, followed by a discussion of possible influences of production parameters on this process.
