Abstract: AWE has embarked on a programme of work to develop an improved intense electron beam diode for flash x-ray radiography machines. In order to understand the performance of the diode, and to validate computer modeling codes, there is a requirement to obtain time resolved x-ray spot size and position data during the 50 ns electron beam pulse.A simple, low cost, time resolved spot diagnostic is described, based around a number of single frame, fast gating intensified CCD camera modules focussed onto a very fast o…
