Commercial High Current Ignitron Development
نویسنده
چکیده
Our overall goal is to develop and qualify devices capable of repetitively switching high peak currents (>1 MA) and large quantities of charge (>500 C). In 1988 we designed and tested a hollow-anode ignitron at levels of up 925 kA and 280 C per shot[1]. This level is three times that previously achieved with standard, commercially available tubes[2]. Our latest designs, developed with the cooperation of industry, incorporate a hollow anode into an industrial ignitron. Prototypes have recently achieved levels of 770 kA and 270 C per shot.

Powered oscillator using ignitron switches.
A 10-MVA-scale resonant oscillator, powered by a pulse-forming network and switched with a pair of commutating mercury ignitrons, was developed for the MST reversed-field pinch plasma-confinement experiment. A novel feature of this circuit is its commutation mechanism, wherein each turning on of one ignitron causes a reverse voltage transient that turns off the other. Two of these oscillators a...

متن کاملMotivations for RLVS and TAVs
In this section, we examine the space launch needs of U.S. military, civil, and commercial space sectors. The potential development and operating costs for a small fleet of military TAVs are reviewed and compared with the costs associated with a small expendable launch vehicle. The potential development costs for commercial RLVs are also briefly reviewed. Next, we examine U.S. launch policy and...
متن کاملPotential for Integration of Commercial and Military Technologies
To achieve the benefits of CMI, advocates call for a relaxation of the regulatory restrictions that segregate weapon system acquisition from common commercial market practice and impose a regulatory cost premium on items purchased by the government. They base their arguments on two types of assumptions. First, they assume that an extensive “dual-use” overlap between commercial and military proc...
