Halo background in laser beam slicing experiments at SLS and SOLEIL

10-MAR-2010, 34 pages [PDF]

Most of the background noise in a laser beam slicing experiment for generation of sub-ps X-ray pulses is due to a beam halo formed from the relics of previous laser beam interactions. Thus the signal to noise ratio deteriorates if the laser repetition frequency is increased. In the context of a planned laser beam slicing installation at SOLEIL for the CRISTAL and TEMPO beam lines, and a planned upgrade of the existing SLS installation for the muXAS/FEMTO beam line, we will investigate the signal to noise ratio as a function of the laser repetition rate and compare it to tracking simulations and to measurements done at SLS FEMTO.
