DRIFT TUBE FOR LINEAR ACCELERATOR (LINAC) WITH FOUR-POLE PERMANENT MAGNETS WITHOUT WELDED CAPS

摘要

A method for producing a drift tube for a linear accelerator, the method comprising the steps of: providing a cap for the drift tube composed of oxygen-free electrolytic pure copper; pressure-inserting the surface of the cap for the drift tube into a core of the drift tube composed, likewise, of oxygen-free electrolytic copper, such that the contact is hermetically sealed; electrodepositing copper onto the seal; and forming a continuous copper sealing strip that completely fills the voids between the core and the cap of the drift tube. The method dispenses with the need for welding and allows the use of oxygen-free copper.
