PBFA-II energy storage system configuration and characteristics

摘要: PBFA-II is the second thirty-six module particle beam accelerator built by Sandia for ICF fusion feasibility studies. Each of machine designed to deliver 2.8 terawatts a central experimental chamber. The total power delivered (100 terawatts) expected permit ignition scaling studies beginning in 1986. energy storage system consists 6.0 MV, 400 kJ Marx generators set an annular oil tank at outer periphery accelerator. In order properly drive machine's downline pulse-forming section and load, generator must erect with first-to-last spread less than 40 nsec. triggered chain pulse amplifiers, low voltage trigger from main control culminating 540 kV, 80 nsec risetime pulses individual generators. then erects 110 kA, 5.3 1.0 ..mu..sec charge section. At this time, entire has been assembled initial testing begun on charging, firing, arming systems. Performance characteristics, as well operating point procedure, are being determinedmore » each support systems, preparation upcoming tests generators.« less
