Abstract: A particle therapy system includes an ECR ion source for production of charged ions, which are accelerated in an accelerator unit that follows the ECR ion source. The accelerator unit accelerates the charged ions to an energy that is used for irradiation, where the magnetic fields of the ECR ion source are matched to operation of the ECR ion source for lightweight ions, such that the ECR ion source is operated in the afterglow mode. In the afterglow mode, an afterglow beam pulse is emitted from the ECR ion source after a microwave resonance pulse has been switched off. The current level of the afterglow beam pulse is higher than a current that is emitted from the ECR ion source during use of the microwave resonance pulse.

Abstract: An electron gun includes a sealed chamber under vacuum. A cathode having an emitting face is placed inside the chamber. An anode forms a sealed window, formed facing the emitting face in one of the walls of the chamber. The anode is capable of allowing electrons emitted by the emitting face to pass through. A biasing apparatus sets up a voltage between the anode and the cathode, capable of accelerating these electrons towards the anode, the electrons thus accelerated forming a beam that passes through the anode. The anode and the emitting face each have a curvature, the curvature of the anode making it capable of resisting a pressure difference between the inside and the outside of the chamber and being designed to cooperate with the curvature of the emitting face to focus the electron beam outside the chamber.
