Photon detection for Cherenkov counters

Oral presentation

Over the last two years the LHCb experiment has commissioned over 500 Hybrid Photon Detectors (HPD) in its RICH detectors. Here we will report about results of the extensive monitoring programme for these novel photon sensitive devices. Recently the first Cherenkov photons produced by LHC beam particles were reconstructed. Data have been taken under a variety of different run...

Photon detection for Cherenkov counters

Oral presentation

We have studied the possibility to use silicon photomultipliers as a single photon detector in a proximity focusing RICH with aerogel radiator; such as counter is considered for the Belle-2 detector. Their main advantage over conventional photomultiplier tubes is their operation in high magnetic fields. Their disadvantage is the relatively high dark noise count rate ( ~MHz/mm2) which can be...

Photon detection for Cherenkov counters

Oral presentation

For the Belle-II experiment, we have been developing a proximity focusing RICH counter with silica aerogel radiator as a new particle identifier in the forward endcap to extend the $¥pi/K$ separation capability up to 4 $¥sigma$ at 4 GeV/c. Our requirements on a RICH photon detector are the following: (1) sensitivity to single photons, (2) immunity to magnetic field, (3) granularity of...
