Description
A new detector to measure the machine induced background at larger radii
has been developed and installed in the CMS experiment at LHC. It
consists of 40 modules, each comprising a quartz bar read out by a
photo-multiplier. Since Cerenkov radiation is emitted in a forward cone
around the charged particle trajectory, these detectors can distinguish
the directions of the machine induced background.
The back-end consists of a micro TCA readout with excellent time resolution.
The performance of the detector modules measured in several test-beam
campaigns will be reported. The installation in CMS will be described, and
first results about operating the detector during data taking will be
given.
