Pulsed x-ray emission by laser-plasma-triggered electron beam

An ultra low timing-jitter pulsed X-ray source was developed. The low jitter characteristic of this X-ray was obtained by using two q-switched Nd:YAG lasers: one was used for triggering a Marx generator, which supplies pulsed high voltage to a flash X-ray source, and the other was for triggering X-ray emission. The pulse width of the X-ray was about 50 ns and the timing-jitter was several nanoseconds. The low timing jitter enabled us to take an X-ray photograph with multiple exposure, so that a clear image of a high-speed rotating fan was obtained.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
