Abstract
A standing wave electron beam accelerator and x-ray source is described. The accelerator has a plurality of on-axis resonant cells having axial apertures electrically coupled to one another by on-axis coupling cells having axial apertures. The accelerator includes a buncher cavity defined in part by an apertured anode and a half cell. The buncher cavity is configured to receive electrons injected through said anode aperture and r.f. focus them into a beam which is projected along the axis through said apertures. An x-ray target is supported in spaced relationship to said accelerator by a support having a smaller diameter than the accelerator.
