Voltage pulse from current preamplifier of multiplier photo-tube is shaped by DL1, which is shorted at one end and terminated at other end with ifs characteristic impedance, to normalize input pulse width at twice 0.5-microsec characteristic delay of line. First stage gives open-loop gain of 118. Second stage gives low-impedance drive for feedback and for following discriminator amplifier. Total loop gain is 17 for bandwidth of1 Mc.-R. Cuikay and T.
