Abstract
The invention concerns an electron gun for the production of an electron beam designed primarily for welding workpieces and including, in a frame, the mechanical facilities required for holding in a coaxial position and electrically insulating a cathode, a filament, a wehnelt and an anode. Gun featured by the fact that the cathode is held by mechanical systems in the coaxial position via several rods made of conductive material, one end of these rods being rigidly fixed with respect to the frame, the other end being applied against the outer wall of the disc shaped cathode, thus forming a positioning clamp for said cathode. The structure allows for the efficient cooling of the internal parts of the gun.
Claims12
An electron gun for the generation of high power density electron beams adapted to the welding of workpieces comprising:
- means for holding in coaxial position and electrically insulated from one another replacable filament, a wehnelt and anode;
- multiple heat and electricity conducting rod means for maintaining the said cathode in coaxial position, one end of each said rod means being rigidly with respect to the said holding means, the other end of each rod means being applied against the outer side wall of the said replacable cathode so as to form a positioning clamp for the said cathode.
A gun according to claimin whichthesaidfasteneers which pass through the end plate are provided with radiator fins protruding inside the hollow portion of the said insulator so that air circulated around the radiator fins may act to remove heat from the fins.
