Abstract:
An electron beam device for producing ion beams, comprising:an electron beam source configured to produce an electron beam; a trap core inline with the electron beam, including a compression magnet configured to compress the electron beam; a first cooling contact in thermal communication with the trap core; a refrigerator system configured to cool the trap core by cooling the cooling contact; a first thermally conductive, solid link between the first cooling contact and the refrigerator system; a collection magnet inline with the electron beam, the collection magnet located downstream of the compression magnet; an outer cold shield substantially surrounding the electron beam source, trap core, and collection magnet; a second cooling contact configured to cool the outer cold shield; and a second thermally conductive, solid link between the outer cold shield and the refrigerator system, wherein the first and second cooling contacts are configured to have a layered construction comprising alternating layers of a rigid, thermally conductive layer and a malleable, thermally conductive medium, the layered construction of both the first and second cooling contacts comprising alternating layers of copper and indium.
