Apparatus and method for entry of charged particles in a particle accelerator and accelerating structure

摘要

The invention relates to a device for entry of charged particles in a particle accelerator, comprising:– a speed modulation in front of the direction, with which a particle beam, which in the device, a velocity modulation can be imposed on, so that, in the further course of a drift path in the particle beam along a density modulation is achieved and, thus, part chen packets can be produced, and– a beam deflector, which the speed modulation in front of the direction is connected downstream of and can be arranged in front of an entrance window of a particle accelerator, and with which during the drift path of the particle beam a transverse deflection of the particle beam can be generated,– a control apparatus for controlling the extent of the transverse deflection, as a result of which the set of magnetic particles, accelerated by the following particle accelerator can be controlled.Furthermore, the invention relates to an accelerating structure with a device of this type, and a corresponding, with the device can be carried out a method for intensity controlled entry of charged particles in a particle accelerator.
