A high-voltage double-pulse induction acceleration component structure

Abstract

The invention discloses a high-voltage and double-pulse induction acceleration assembly structure. A Blumlein line A is connected with an acceleration cavity A and an acceleration cavity B through four first high-voltage cables with the same length; a Blumlein line B is connected with a water medium high-voltage delay line through two second high-voltage cables which are connected in parallel; an output end of the water medium high-voltage delay line is further connected with the acceleration cavity A and the acceleration cavity B through four third high-voltage cables with the same length. Compared with a structure comprising a plurality of pulse formation lines, and a primary power supply and a triggering power supply which are matched with the pulse formation lines, the structure of the double-pulse structure disclosed by the invention is greatly simplified; in a charging process of the Blumlein line A and the Blumlein line B, a charging leakage current pulse with a time quantity microsecond is generated; polarities of the current pulse and main pulse current are opposite; magnetic cores of the acceleration cavity A and the acceleration cavity B are reset when the current pulse passes through the acceleration cavities, so that the problem that the resetting is difficult is solved.

Description

technical field [0001] The invention relates to a multi-pulse accelerating electric field generation technology, in particular to a high-voltage double-pulse induction acceleration component structure. Background technique [0002] The induction acceleration component composed of the induction cavity and the corresponding pulse power system is the basic unit of the linear induction accelerator. The high-voltage short pulse generated by the pulse power system excites the magnetic core in the induction acceleration cavity, and the pulse electric field is induced on the acceleration gap to realize Acceleration of intense electron beams. The pulse high voltage fed into the acceleration cavity usually needs to reach more than 200kV. Due to the limitation of the switching capacity, it can only be generated by the pulse forming line at present. After the forming line is discharged, it needs a long switch insulation recovery time and charging time, so it can only work in Very low r...
