Laser-trigger system design for PBFA II

摘要: A revolutionary design for triggering a multitude of high-voltage gas switches is in the process being implemented and tested at Sandia National Laboratories. This new laser system PBFA II consists five major subsystems. The first subsystem KrF which injects as much 4 J uv radiation into optical train. second train consisting over 300 components that split beam 36 equal beamlets are respectively directed trigger section PBFA-II switches. third, alignment system, provides convenient, reliable, low-cost method sensing degree with respect to fourth mechanical assembly supporting containing low vibration, environmentally controlled manner. fifth control diagnostics. These subsystems act concert provide low-maintenance repeatable, repeatable performance, will fire 36, 5.5-MW, total firing spread last ns.
