Abstract

In a previous series of experiments, an existing Thomson scattering (TS) setup was applied for measuring electron temperatures and densities in a vacuum arc discharge in tin vapor, which is an experimental version of a candidate source for high power EUV generation. These experiments were succesful only for the so-called prepinch phase of the discharge, due to the high level of background radiation emitted in other parts of the plasma evolution. We have designed and built a new setup for sub-ns TS, based on a laser with shorter pulse duration, a faster camera, and an optical delay line in the laser path. Results of experiments on previously inaccessible phases of the discharge are presented. From these, a more complete picture of the evolution of the vacuum arc discharge can be derived.
