Assignee:

Hitachi Zosen Corporation - Suminoe-Ku

International Classification:

A61L 2/08
B65B 55/08

US Classification:

422 22, 2504923, 2504931, 2504921, 31511181, 31511191

Abstract:

Improved electron beam sterilization apparatus and shielding techniques for use in are provided. A controller modulates an electron beam when sterilizing an interior to an object to ensure that adequate dose is received. Sterilization carousels are configured with input/discharge feeds to reduce the possibility of humans being exposed to dangerous levels of radiation. The system reduces the amount of shielding required to thereby lower cost of installation.

Filed:

Jul 29, 1991

Appl. No.:

7/737240

Inventors:

Tzvi Avnery - Winchester MA
Arthur W. Sommerstein - Lynn MA
Rolfe W. Graham - Woburn MA

Assignee:

Energy Sciences Inc. - Wilmington MA

International Classification:

H01J 2946
H01J 2956

US Classification:

315 14

Abstract:

A novel electron beam apparatus and technique wherein a plurality of longitudinally extending heated filaments is employed, each similarly offset laterally of a central longitudinal axis, but with successive filaments alternately disposed on opposite sides of said axis and cooperating with a first low velocity accelerating stage comprising staggered grid slots and openings, and a high velocity second accelerating stage to provide long uniform longitudinal electron beams.
