EML bnrrel kngthPreacceleraior barrel Ien.eL 425 3 m ImAbstract -A small-bore hypervelocity Electromagnetic Imincher laboratory research facility has been developed which has launched a 2-g projectile to it velocity in excess of 3.5 knilsec. This turn-key laboratory includes a 1 cm, square bore railgun with a helium gas preaccelerator; a modular 328 kJ capacitor bank; a fiber-optically linked PIX-based control system with a graphical operator interface; it CAMAC-based diih acquisition system with current, magnetic, and prqjectile position diagnostics; and a flight range which provides in-flight velocity measurements and safely stops and contains the prqjectile. The control system is designed to fire the preaccelerator and upon receipt of an optical trigger signal, fire the capacitor bank modules simiiltaneoiisly or in a staggered mode.During initial testing at GA, armature separation and ~ti~lling were observed which limited the overall performance of the system. Changes in pulse S h i I I X and bore iIli1teriitls significantly improved the performance of the system. This paper includes a discussion of the system, methods used to minimize armature separation and improve performance, and test results.
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.
