Scintillation detectors produce light as they absorb energy, and these light flashes result in the release of a proportionate number of photoelectrons at the cathode of a photomultiplier tube (PMT). Each of the ORTEC Photomultiplier Tube Bases is designed to accommodate a particular type of PMT to distribute the operating voltages to all its elements, and to derive signals from it.
Classically, high voltage has been supplied to the PMT base from an external supply. More recently the supply was integrated into the base itself and now even the multichannel analyzer is integrated within the PMT base. Models of all of these types are available from ORTEC.
