Abstract

In this paper, a new picosecond synchroscan streak camera system, including our own synchroscan streak image tube, RF streak circuits and CPM laser system, has been reported. The temporal resolution of the streak image tube itself was 300fs and spatial resolution was 50 1p/mm. The dynamic sensitivity of deflection was 10cm/kV and factor of merit was greater than 100, which decreased the requirement of the RF deflection power to the streak circuits. Our RF streak circuits consisted of PIN diode, electric second harmonic selector, pre-amplifier, power amplifier and impedance matching unit, which gave maximum RF power of lOw and operation frequancy of 200MHz. The CPM dye laser system developed in our laboratory was pumped by an Ar? laser system and presented the shortest pulse duration of +5fs and repetation rate of 100MHz with acceptable stability. The preliminary experiments showed that the temporal resolution of 2ps of the whole camera system was obtained which was limi-ted by the stabilities of above laser system and RF streak circuits.
