Low-Level Linear Microsecond Gate

Abstract

A linear transmission gate for use in scintillation counter coincidence experiments is described. The gate is suitable for negative pulses of microsecond duration and is linear over a range of 0.01 to 5 v. The circuit is relatively simple, uses no vacuum tubes, and is reliable over long periods of use. The use of low‐level gates can increase the usable counting rate of a multichannel coincidence system by an order of magnitude.
