Abstract:Exploding foil initiators (EFIs) offer several safety and timing advantages over other means of initiating high explosives. In order to increase the knowledge about the barrel diameter on sensitivity of HNS‐IV, several samples with different barrel diameter were investigated. Mean threshold voltage, and flyer velocity were measured and compared. Meanwhile, we present the flyer images with restricted condition of EFIs during flight by X‐ray phase contrast imaging system at the 45 TW laser facility at China Acad… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
