A number of circuits using transistors and tunnel diodes were designed during the past year for counter experiments at pulsed accelerators. The circuits include coincidence circuits, pulse limiters, pulse amplitude discriminators, pulse amplifiers, fanout circuits, trigger circuits, and fast scalers. These individual units are compatible with each other in that the output of any one may serve as the input to another, and all interconnecting cables are 50 impedance. They are desined to work with both small and large photomultiplier pulses. Two related developments are also presented. One is a high voltage supp1y for use with highcurrent photomultipliers. The other is a pulse train generator and synchronizing circuit, the combination of which is used for duty cycle tests. (auth)
