A setup for recording the picosecond dynamics of radiation of semiconductor targets in a gas diode

On the basis of a D DDDDe generator of high-voltage subnanosecond pulses, an experimental setup for recording the picosecond dynamics of excitation of optical radiation in semiconductor targets (plates) in strong electric fields has been developed. Semiconductor targets were placed between the electrodes to which voltage pulses with an amplitude of up to 150 kV were applied. These pulses were delayed by a coaxial transmission line by 20-30 ns. This technique allowed realization of triggering in advance the sweep of an electron-optical camera and studying of the dynamics of emission from targets with a resolution of 5 ps at a synchronization accuracy close to the rise time of an acting high-voltage pulse.
