A RADIOACTIVE SOURCE OF EXPONENTIALLY DISTRIBUTED INTEREVENT INTERVALS WITH ELECTRONICALLY CONTROLLED RATE AND ORIGIN PARAMETERS.

Abstract

The equipment described utilizes the fact that time intervals between successive disintegrations in an appropriately chosen radioactive source are exponentially distributed. A source and detector drive a probability unit which reduces the input distribution rate parameter by as much as two decades. The origin parameter is then introduced by a gating circuit which eliminates pulses which follow their predecessors by less than a specified number of seconds. The system is reliable, and easily calibrated and adjusted. (Author)
