Time‐to‐Pulse Height Converter of Wide Range

摘要

A time‐to‐pulse height converter covering the range from millimicroseconds to minutes is described. A simple 5‐component passive circuit for scanning times above 50 μsec is included also. The converters can measure several events per time scan related to one starting event. They are designed as plug‐in units for an oscilloscope, and utilize its sweep and other circuits. The use of the converters is discussed and includes scanning of negative time and inverted operation for reduction of counting losses. Notes on testing, calibration, and dead times are given, as well as examples of nuclear experiments to which they have been applied.
