Description
The problem of coherent X-ray radiation formed in crystalline undulator (CU) by positron bunch with modulated density is solved. The CU parameters are calculated, the choice of which provides coherent radiation of the positron bunch (with parameters of LCLS) modulated in the SASE FEL process. If modulation depth is not too small, then an X-ray photon beam is formed, more powerful and monochromatic than in the case of SASE FEL. This approach can be used in the experiment for determination of this important parameter, viz., the modulation depth.
