Abstract
Cherenkov threshold detectors (XCET) are used for identifying particles in
the experimental areas at CERN. These detectors observe Cherenkov light emitted
by charged particles travelling inside a pressurized gas vessel. A key
component of the XCET detector is the 45-degree flat mirror reflecting the
Cherenkov light towards the photomultiplier (PMT). A thorough analysis and
optimization was conducted on the design and materials of this mirror, along
with the surface coatings and coating techniques. A suitable manufacturing
process was selected, and the first mirror prototype was produced, installed,
and tested in the East Area at CERN. Experimental data obtained during beam
tests is presented to assess the efficiency of the new coating and materials
used.
