Abstract

A new pulse light source has been developed for flash photolytic investigations. It consists of a z-pinch operated with a 33-kV, 4.85-kJ condenser bank, and produces light pulses of 0.2 μsec duration with a maximum continuum radiation density exceeding 100 W Å−1 cm−1 sr−1. Details of construction and measurement techniques are given, and the possibilities of application of this light source in flash photolysis are discussed.
