Paper Abstract

Despite a great deal of effort to improve time resolution of streak cameras, the best reported time resolution remained just under one picosecond for more than a decade. However, the sensitivity and resolution of these devices have improved substantially over this time. In this paper the design of a very high performance streak camera, capable of resolving one picosecond on 200 parallel channels with single photo-electron detection capability: the Dellistrique 2S. The system comprises of a streak tube type Picotron 200 with a photocathode resolving 200 spatial channels along a slit and with an extraction field near the photocathode of greater than 16 KV per cm and with a non saturating phosphor screen as the main component. There is post streak tube intensification of 30,000 at the streak tube output wavelength which increases both the sensitivity of the system. The intensifier is coupled to a CCD readout device fibre-optically for producing a two dimensional image with a dynamic range of greater than 500. The camera can be operated at a repetition rate of between 80 MHz and 240 MHz using R.F. scanning methods. Upto 20 parallel channels have been tried with parallel information recording, which is well below the tube's capability of recording 200 independent channels. The image is virtually distortion free across the whole usable screen length of 45 mm for a large screen tube.
