High intensity x-ray beam
Webhigh resolution x-ray radiography facilities requires high current electron beams to be focused to a millimeter spot size on an x-ray converter throughout the entire current pulse. Web摘要：. An all-x-ray pump and probe capability is highly desired for the free-electron laser community. A possible implementation involves the use of an x-ray mirror downstream of the sample to backreflect the pump beam onto itself. We expose silicon single crystals, a candidate for this hard-x-ray mirror, to the hard-x-ray beam of the Linac ...
