Paper Abstract

The fusion diagnostic community require optical recording instruments with precise time resolution covering a dynamic range of many orders of magnitude. In 2012 the Laboratory for Laser Energetics, Photek and Sydor Instruments embarked on the re-design of an improved streak tube for fusion diagnostics. As a baseline, we started with the Photek STY streak tube because the tube body can accommodate a 35 mm long photocathode. Electron optical modelling was carried out by both Paul Jaanimagi in the US and by Photek in a parallel exercise. Many changes and modifications were made: the time resolution was improved to 5 ps, the usable cathode length was increased from 20mm to 32 mm under high extraction field operation and the off-axis spatial resolution was substantially improved compared to other tubes of this format. Several tubes have been built and tested in a Sydor ROSS-5800 streak cameras, and show greatly improved resolution (MTF).
