Half-and-half HFCG with double-end initiation

TL;DR

This paper presents a novel helical flux compression generator design with double-end initiation, significantly increasing power output and reducing pulse rise time compared to conventional single-end designs.

Contribution

The paper introduces a new design approach for helical FCGs with double-end initiation, achieving higher power and faster pulse rise times.

Findings

Power increased by 60% with double-end initiation

Pulse rise time shortened by 83%

Switched current increased by 35% using an electro-explosive switch

Abstract

Design of helical flux compression generator with double-end initiation is described. The developed design approach makes it possible to increase the power in the load by 60\% and shorten the rise time of the pulse by 83\% in comparison with a conventional helical FCG that is made in the same dimensions but with the single-end initiation of explosive. When using an electro-explosive opening switch, the developed FCG allows one to increase the switched current by 35\%.
