Abstract

We have investigated the characteristics of a transmission type x-ray streak camera and performed the measurement of implosion process of laser fusion plasma with this camera. The streak tube contained two channel plates inside to obtain a higher sensitivity. The maximum sweep speed was 1.5 mm/sec and the time resolution was es-timated to be approximately 15 ps. The implosion time and velocities of glass microballoon plasma produced by "Gekko II" two beam glas, laser system were measured and were about 475 psec, ~10 7cm/sec, respectively. These results were agreed well with the results of plasma simulations in which one dimensional, one fluid and one temperature model were used.
