Abstract
A linear beam tube has multiple heat pipes formed integrally in the cavity wall between the beam collector and external air cooling fins. The heat pipes use sintered copper pellets on the walls of the pipes as wicks to facilitate the return flow of liquid condensed at the fins. Circumferential channels connect the heat pipes at each end to reduce vapor lock effects. Vapor surface area enhancement rods are used at the heat source to increase the transfer rates of heat into the fluid.
