Abstract

749,567. Discharge apparatus. HERAEUS GES., W. C. Jan. 11, 1954 [Jan. 9, 1953], No. 745/54. Class 39 (1). An apparatus for bombarding matter with a high energy electron or ion beam has a highvacuum beam generating chamber 1, a working chamber 7 at atmospheric pressure and a series of intermediate chambers 5, 6 at successively increasing pressures, the chamber 6 being at a pressure at least equal to that in the working chamber and filled with an indifferent gas or a gas participating in a reaction in the working chamber. Chambers 1, 5 are connected to pumps. Chamber 6 is open to the atmosphere at 12. The apertures in the chamber partitions 13, 14, 15 are 0.5 to a few mms. in diameter. The partitions may be funnel-shaped and designed to act as electrostatic or magnetic lenses. They may be provided with cooling arrangements. The partitions may be of metal, glass, quartz or ceramic. The apertures may be provided in diaphragms which are mounted in the partitions. Beam deflecting arrangements may be provided in the chamber 6. In a modification gas withdrawn by the pump 11 from the chamber 5 is fed back to the chamber 6. Gas lost to the chamber 1 and withdrawn by the pump 10 is made up by the controlled admission of gas into the chamber 5 from a supply container. The Specification refers to a variety of applications for the apparatus including the generation of X-rays, light or sound, the boring of holes in solid bodies and the carrying out of chemical reactions.
