Abstract
A modular base for a position sensitive Photo-Multiplier Tube (PS-PMT) that can be connected to other similar modular bases to form arrays of PS-PMTs. X and Y resistor chains are provided within the base to connect all X and Y coordinate anodes from the PS-PMT, respectively. An amplifier is provided at each end of each resistor chain to amplify output signals when the base is used alone; not connected to other bases. Jumpers associated with each amplifier are provided to include the amplifier in the output signal path or bypass the amplifier and connect to jumpers of other bases. When a base is used alone, the jumpers, which provide either an X or Y output signal, are set to include the amplifier in the output signal path. When two bases are connected together, the jumpers are set to bypass their associated amplifiers and connect the respective X or Y resistor chains of the two bases. The present method advantageously maintains the number of required amplifiers for each X or Y coordinate at two, no matter how many bases are used in the a row or column.
