Abstract:
1. An X-ray source comprising: a waveguide having at least one sidewall and a cavity extending therethrough; at least one electron emitter positioned on an inner surface of a first sidewall of the waveguide for generating at least one electron beam; at least one an angled opening extending through a second sidewall, the at least one angled opening forming at least one pathway through the second sidewall, wherein the at least one pathway has two opposed sides; at least one stationary target positioned on an inner surface of one of the two opposed sides of the at least one pathway, the at least one stationary target receiving the at least one electron beam for generating X-rays; and a conduit coupled through the at least one sidewall of the waveguide providing microwaves from a microwave generator into the cavity of the waveguide, the microwaves generating an electric field for accelerating the at least one electron beam toward the at least one stationary target; wherein the second sidewall is opposite the first sidewall; and wherein the two opposed sides of the at least one pathway each having at least one cooling channel adjacent thereto and extending through the second sidewall.
