Title:
ARC-SHAPED MULTI-FOCAL POINT FIXED ANODE GATE CONTROLLED RAY SOURCE
Document Type and Number:
WIPO Patent Application WO/2019/129008
Kind Code:
A1
Abstract:
Provided is an arc-shaped multi-focal point fixed anode gate controlled ray source, comprising an arc-shaped ray source housing, a ray tube bracket, a plurality of fixed anode reflected ray tubes and a plurality of gate controlled switches, wherein the plurality of fixed anode reflected ray tubes are fixed on the arc-shaped ray source housing by means of the ray tube bracket, and the focal points of the plurality of fixed anode reflected ray tubes are distributed on the same distribution circle; and the plurality of gate controlled switches are correspondingly connected to the plurality of fixed anode reflected ray tubes. By splicing the plurality of arc-shaped multi-focal point fixed anode gate controlled ray sources into an integral ring structure, the focal points of all the fixed anode reflected ray tubes therein can be distributed on the same distribution circle. The above-mentioned arc-shaped multi-focal point fixed anode gate controlled ray source is simple in structure and lower in cost, can generate a ray of sufficient strength, and has a sufficient number of focal points distributed in a circumferential direction.
