Abstract

A recording of temporal reference on picosecond streak camera images requires to transmit laser pulses of different wavelengths through optical fibers (O.F.) onto streak cameras. We describe the O.F. network installed on the PHEBUS laser to provide streak cameras and photomultipliers with a 200 ps pulse. We also describe the tests performed on various fibers to evaluate their transmission (? = 0.35 tim) and on photocathodes to get the best photons-electrons conversion efficiency in open X-rays tubes. Then we describe the experimental test set up also installed to easily check the sweep linearity and speed and also the amplitude response of X-rays cameras, using this fiducial system. We show practical results of those tests, and some laserplasma interaction experimental results.
