New developments and results on high-spatiotemporal-resolution x-ray streak cameras

ABSTRACT High resolution X-ray streak cameras built around bilamellar tubes have been developed for a long time in CEL-V2. The C850X camera is the last step of those studies. We describe here the different versions of the camera; we also present theexperimental results (temporal resolution 2 ps in conjunction with a dynamic spatial resolution > 15 lp/mm ) obtained inENSTA on a 60 fs UV laser, which match our theoretical predictions.The improvements of the C850X electronics have also been implemented on C750X (theP750X tube of that camerahas the same structure as that of C850X, but its deflection plates are replaced by a 5Of meander stripline, which allows highersweep speeds).We present the status of that development, the improvements accomplished on the sweep circuit and the first resultsobtained with that device. 1 - INTRODUCTION Streak cameras used in laser interaction experiments at Centre dEtudes de Limeil-Valenton have been the subject of years of tube development with the help of the PHILIPS COMPONENTS3 company. In particular the new concept of
