Paper Abstract

The framing image tube camera has some intrinsic advantages. It has got some applications in ICF and X-ray laser field. But there are two main problems with this technique: the loss of spatial resolution at short exposure time,a nd the electromagnetic disturbance in the experimental area. In order to solve these problems, we have taken several measures: to improve the design of the image tube and the electronics and to strengthen the shielding. Additionally, in intense X-ray pulse we use MgF2 as cathode material instead of Au and CsI to reduce the space charge effects. The experiments in high power laser area have shown that 3 frame images can be provided with 75 ps (FWHM) exposure time and dynamic spatial resolution of 6 lp/mm. Some physics results of high power laser-plasma interaction have also been obtained.
