Development of picosecond x-ray framing camera

X-ray picosecond framing photography using optical framing and deflection shuttering has been proposed and demonstrated in our laboratory for several years. Four frame dynamic images have been obtained with 170psec exposure time. The recent modification and developments of the image tube and camera are described. The aim of our modification is to decrease the exposure time and improve the dynamic spatial resolution. Resolution of 5 1p/mm has obtained. The dynamically test the framing camera which uses demountable image tube, a mode locked Nd: YAG laser system with two stage second harmonic generator has been built. Secondary electron emission has been used to imitate the X-ray photoemission in the testing of framing camera.
