“…Many circuits have been reported for generating a sweep pulse for the streak camera. These utilize various kinds of fast switching elements such as krytron (Bradley et al 1972), power-beam microwave triode (Alcock et al 1970), laser triggered spark gap (Alcock et a11970; Schelev et a11972) as well as avalanche transistors (Cunin et al 1980;Baker 1991). The transistorized circuits available to date provide rise times of 1.5 to 2 ns depending on whether avalanche transistors are used in a series stack mode or in a Marx bank configuration.…”

We describe the development of an optical and an X-ray streak camera with picosecond time resolution. The entire peripheral electronics and testing systems have been developed indigenously. Both the streak cameras provide ~ 15 ram/1 ns streak rate with a sweep voltage of ~ 1 kV amplitude and rise time of 1 ns. The time and spatial resolution of the optical streak camera have been found to be ~ 17 ps and 100 #m respectively. The sweep pulse generator developed for this purpose provides a step pulse of rise time ~< 1 ns and amplitude ~ 2 kV. The laser diode used for testing the optical streak camera provides multiple pulsation when the pump current is increased beyond a critical threshold.

Dynamic range measurements have been made on EEV P8307 (Photochron II type) streak image tubes with both internal microchannel plate (MCP), and externally coupled wafer intensifier tube, image amplification. When ananged for equal radiant gain at 560 nm, both configurations showed comparable dynamic range of11OO and -29OO for 30 P5 and 100 p5 duration (fwhm) input pulses respectively. The variation in dynamic range with photocthode current density was also measured and the results compared to a computational model based on Coulomb repulsion in the image tube. Experimental data are compared to the model and shown to be in moderate agreement.

“…2 was lens coupled to a magnetically-focussed intensifier u and the streak image was recorded on Ilford HP5 photographic film. 21 Typically the laser pulses had durations in the 80-110 ps range. 21 The passively mode-locked neodymium:glass laser with the pulse duration of 5 ps and pulse train length of -400 ns was used as the light source.…”
