Broad band amplification unit, has been designed to amplified the photo- multiplier tube (PMT) output pulses for a fast photon counting tube type EMI 9863Q.
Two integrated circuit, SL560C, SL550D are used in the unit implementation, SL560C for preamplifier stage and SL550D for amplifier stage.
A special metallic box, with a suitable dimensions is used with each stage for mounting the board and shielding from the spurious pulses.
