Abstract
Three kinds of x-ray streak cameras in wavelength regions ranging from several A to 2000 It are developed. A time resolution in the shorter wavelength region is successfully improved to about 10 ps by adopting most desirable parameters, especially high electric field and by minimizing velocity distributions of electrons emitted from a photo-cathode. The design and the performance of these streak cameras are described. Plasma experiments are performed by a YAG laser with 30 ps of pulse-width and 100 mJ of output energies. Both time and spatial resolutions are investigated by using higher harmonics of a YAG laser and soft x-rays from laser-produced plasmas.
