Paper Abstract

The sequential pulsed white light source is widely used for synchronous illumination in high-speed photography. Usually, the move range of the object is large and wide spectral coverage of the light source is required. In this case, laser is not a suitable illumination light source. Thus it is better to use a gas discharge tube. When discharge energy of every flash is larger than 10 J, and a flash frequency reaches 2 X 104 Hz, the output power of the circuit should be high up to several hundred KW. In fact, the repetition frequency of the strobe will be restricted by charge velocity of the circuit if a traditional monocircuit for charge and discharge is used. In addition, high-voltage resistant and large current quick switch is very expensive. So the above mentioned traditional type of strobe is difficult to spread widely. We have designed and tested a novel high frequency strobe driven by multicircuit. The strobe consists of a few charge and discharge circuits with several small thyratrons, flash Xe tube and its preionization circuit, trigger generator and amplifier, and trigger signal distributor. Its principal parameters are summarized as follows: flash pulse width, 0.2-10 microsecond(s) ; average power, 1 X 104 approximately equals 1 X 107 W; discharge energy per flash, 1 approximately equals 15 J; flash frequency, 1 X 103 approximately equals 5 X 105 Hz. In this report, we described the principle of the strobe and the choice of the main parameters.
