Abstract
The purpose of the research is to define the most adequate manufacturing process for the dump of a linear deuteron accelerator. The deuteron beam can be pulsed as well as continuous with energies up to 9MeV. The maximum beam power is 1.12MW corresponding to a beam current of 125mA.The requirements on the surface on which the deuterons will be stopped are quite demanding and the length and slenderness of the cone poses a considerable difficulty in the manufacturing process.The design of the beam dump is based on a copper cone 2500mm long, 300mm aperture and 5 to 6.5mm thickness.Basically only two technologies were found feasible for the manufacturing of the cone: Electroforming and Electron Beam Welding (EBW).The article shows the main results found when manufacturing different prototypes.
