The invention relates to a method for closed-loop control of an X-ray pulse train having a first multi-amplitude X-ray pulse and a second multi-amplitude X-ray pulse generated by means of a linear accelerator system, the method comprises the following steps: modulating a first electron beam generated by means of an electron source of the linear accelerator system for a first radio frequency pulse duration, wherein a first multi-amplitude X-ray pulse is generated when the first electron beam is modulated; measuring a time-resolved actual value of the first multi-amplitude X-ray pulse by means of the measuring unit; adjusting the at least one pulse parameter by means of the control unit as a function of a comparison of a predefined multi-amplitude X-ray pulse profile and the measured time-resolved actual value; and modulating a second electron beam generated by means of the electron source in accordance with the at least one adjusted pulse parameter for a second radio frequency pulse duration in order to genera
