Voltage Dividers & Electronics

Scintillation detectors usually employ a Voltage Divider (VD) network to operate the PMT. This sometimes called “bleeder network” defines a potential (voltage) difference between the cathode, dynodes and anode of the PMT. The exact design of this network is of influence for proper working of the scintillation detector. Some details of voltage divider networks are discussed below. The descriptions below are not exhaustive; for more details we refer to the photomultiplier manufacturer’s literature.
