Optoelectronic system for investigations of non-stationary arcs

Abstract

A simple system for the investigation of space and time changes of non-stationary arcs in the spectral range 400-1100 nm is described. The system consists of a monochromator, an array-photodetector, amplifiers, a multiplexer, a transient recorder and a computer with peripherals. The arrangement and evaluating procedure was tested on a decaying high-pressure mercury arc and during observations of a switching arc in SF6.
