Energy Storage Options for Shiva Upgrade
Abstract
The Shiva Glass Laser at LLL will use 20-25 MJ of Capacitive energy storage. An improved laser system is proposed that will increase this energy requirement by a factor of ten: 25 MJ for Faraday rotators, and 150 MJ for flashlamps. This paper discusses alternative options to capacitors for driving both types of loads. Included are homopolar generators that discharge in ~ 0.1 sec that will drive Faraday rotators directly. Similar generators can be used to drive inductive stores for flashlamp power. The features of the flashlamp system include a wide distribution of 10kJ load elements, and a half-millisecond discharge time requirement. The possibilities of providing open-switching for inductive storage and of driving many flashlamps in parallel are discussed.
