Abstract

A device to control an electron beam for the generation of x-ray radiation, has an electron emitter to generate an electron beam, to which emitter an emitter voltage can be applied, a diaphragm, at least two control elements associated with the diaphragm to affect the electron beam, and switching arrangement with which at least two different electrical voltages can be applied to the at least two control elements. The same electrical voltage is applied to each of the at least two control elements. Upon switching the voltage, an electrical circuit that delays the setting of the respective voltage at the one control element is associated with the connection line of the one control element with the switching arrangement to switch over the voltage. The invention moreover concerns an operating method for the device and an x-ray tube provided with the device.
