Smith-Purcell radiation as a base of Free Electron Lasers is actively studied experimentally and by simulating. Usually the beam is supposed to move at some distance above the target. In practice the distance is tried to decrease so that the beam passes very close to the target surface. Experimental data contains the information about grating heating. The authors of article* suggested the cause of the heating is that the beam skims the grating surface. Developing the method used in**,*** we give the analytical description of the X-Ray radiation arising when the beam of charge particles moves parallel above the periodical target, but the part of the beam crosses the target. The radiation arising is the superposition of Smith-Purcell radiation and transition radiation from the grating. This radiation determines the process of beam bunching and following gain of radiation.
