COMPASS RICH-1

RICH-1 is a large acceptance gaseous RICH using 3m of C4F10 as radiator and MWPCs with CsI photo-cathodes as VUV photon detectors. The main characteristics of this RICH are the large acceptance and the use of far UV photon detectors, which implies large dimensions, UV transparencies of the elements...

Description
Summary:RICH-1 is a large acceptance gaseous RICH using 3m of C4F10 as radiator and MWPCs with CsI photo-cathodes as VUV photon detectors. The main characteristics of this RICH are the large acceptance and the use of far UV photon detectors, which implies large dimensions, UV transparencies of the elements up to the photo-cathode, and good UV mirror reflectance. We give a description of the detector, first results about its performances and a report about various technological achievements required by this challenging project.
