Time Resolved Recording of Arc Spot Formation on Cold Cathodes

Abstract

An experimental set-up is presented, which allows to investigate the interaction of a dense plasma with a cold cathode. The ignition of arc attachments is recorded by electrical measurements, high-speed photography and time resolved spectroscopy. The electrodes are prepared in different ways for reproducing fine microscopic surface structures. Pictures and measurements are shown for a polished Al-electrode.
