ELECTRON BEAM SYSTEM

摘要

Apparatus for electron beam treatment of three-dimensional parts that includes cavities in a shielded rotating drum that preferably includes additional rotation mechanism for rotating parts within cavities in said drum. Radiation associated with the electron beam emitter is substantially shielded by the combination of the drum and the additional radiation shielding. The rotating drum is preferably made of at least four sections axially stacked, and its shielding properties are enhanced by including lead filled holes drilled in the sections.

主权项

1. An apparatus for electron beam treatment of three-dimensional parts comprising:
an electron beam emitter; a rotatable drum constituting a radiation shield for said electron beam emitter and having a generally cylindrical surface and two ends wherein said surface has a cavity on its generally cylindrical surface, with said cavity sized to fit a three-dimensional part to be treated; additional radiation shielding surrounding said electron beam emitter except for a portion of said rotatable drum, whereby the electron beam emitter is substantially shielded by the combination of the drum itself and the additional radiation shielding; and, wherein said rotatable drum is rotatable about a first axis from a loading position free of substantial radiation while said electron beam emitter is operating, to an irradiation position in which the parts are subject to the output of said electron beam emitter; and also including a part rotating mechanism having its axis of rotation positioned differently than the axis of rotation of said rotatable drum.
