Preamplifiers / Detectors
CAEN’s portfolio of preamplifiers covers a wide range of detectors, including diamond, fission chambers, GEM, ³He/BF₃ tubes, PMTs (suitable for scintillators), proportional/ionization counters, proton-recoil detectors, RPCs, segmented silicon, bulk silicon, and SiPM/MPPC. The table below indicates the preferred (though not exclusive) pairings. For complete and precise specifications, please refer to each model’s data sheet. Additionally, an application note, AN8616 – CAEN Preamplifiers selection guide, is available to assist in the choice of preamplifiers.
