    "abstract": "The amplitude of Parametric X-ray radiation emitted coherently by a bunch of\nelectrons crossing a crystal (CPXR) is calculated. When the bunch density is\nmodulated with a longitudinal period close to the X-ray wavelenght,\nconstructive many-electron interferences enhance the intensity by Nb *\n|F(K)|^2, where Nb is the number of electrons in the bunch, F(K) the bunch form\nfactor and K a specified wave vector. CPXR can be used to test the\nmicrobunching in a X-ray free-electron laser.",
