A conceptual design for an actively cooled high-average-power electron-beam absorber (for space power applications)

A conceptual design of an electron-beam absorber system that uses water as both an energy absorber and a cooling medium is presented. This configuration uses an aluminum window to separate the water absorber from a vacuum beamline. Such an arrangement has several desirable features. First, any necessary reconfiguration for an increase or decrease in run time and/or beam power is minimal. Also, the subsystems use current technology. A point design for the window, the absorber tank, and its subsystems is described. >
