Description
The hollow electron beam is injected by a cathode immersed in the magnetic field generated by a set of solenoids. The sum of these components is called electron gun and its geometry evolved over time in order to guarantee sufficient performance in terms of electron density, hollow beam dimensions and gun compactness.
The energy carried by the electrons is dissipated in a dump system in charge of receiving up to 50 kW (conservative value) of power and transfer them to a water cooling system. Feasibility studies of the dump have been performed in order to identify a proper design philosophy and highlight the critical aspects.
