Review of results, obtained by using recently proposed new imaging detector, based on formation of color centers in LiF
crystal and LiF film, for in situ high performance measurements of near-field and far-field properties of soft X-ray lasers
(SXRL) beams is presented. Experiments have been carried out with laser-driven transient-collision plasma SXRL and
free electron SXRL beams. It was demonstrated that due to favorable combination of high spatial resolution, high
dynamic range and wide field of view this technique allows measuring not only intensity distribution across the full
beam and in local areas, but also permits to evaluate coherence and spectral distribution of radiation across the beam.
Experimental diffraction patterns in the images of periodical structures are analyzed by comparison with the modeled
ones in the last case. The estimated accuracy of measurements is between 10-20%.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
