Abstract :
Low power photomultiplier base circuits, using high voltage FETs in the voltage divider, are described. Two examples of design are presented. One consists of P channel FETs for all stages of dynode and features extremely low stationary current(20 ¿A). The other consists of N channel FETs for the last 3 or 4 dynodes and the stationary current is about 130 ¿A. They ensure good linearity at high counting rates(up to the average anode current of 100 ¿A).
