What is CLARO

The CLARO is a chip designed for fast single photon counting with photomultipliers.
Its primary application is in the upgrade of the RICH detectors of the LHCb experiment at CERN.

The main features of the CLARO are:

• Recovery time < 25 ns to sustain counting rates up to 40 x 10⁶ hits/s
• Power consumption ~ 1 mW/channel 
• Radiation tolerance up to 1 Mrad (10 kGy), 10¹³ cm^-2 hadron fluences
