C 850 X-Ray Streak Camera With Optimized Spatio-Temporal Resolution

We present here the P850X streak tube which is a high spatio-temporal resolution X-ray converter tube designed for laser interaction X-ray diagnostics. This tube experiments a new design of electron optics allowing separate focusing of the beam along the temporal and spatial axis. It includes a small dimension screen which must be coupled, for use in X-ray diagnostics, to an image intensifier. To take into account the high resolution of the P850X tube this image intensifier has been improved. Moreover reduced dimensions of the screen and of the associated image intensifier are well fitted with a direct electronic (CCD) readout recording. We also describe the new camera built around the tube, which presents a completely new structure, including a digital monitoring of all the high voltages applied to the tube.
