A fast linear gate circuit

Abstract

An electronic gate circuit is described, which is linear for pulses up to 10 V over an impedance of 200 Ω. The gate-pulse width is determined by an external clipping cable and can be varied from 500 ns down to 40 ns. The input can be of either polarity. The gate incorporates a fixed, well defined dead-time of about 50 μs, which assures stable operation also at high counting rates.
