Particle Beam Fusion Acceleratr-I (PBFA-I)

Abstract

The first Particle Beam Fusion Accelerator (PBFA-I) has recently completed its operational series of tests. It provided 30 TW into 36 power flow lines terminated in electron beam loads at the accelerator's center. The outputs were 2 MV at 15 MA for a 40 ns pulse which provided 1 MJ of output energy. During the accelerator develcpament, several ways of modifying and reconnecting this modular, few MV output pulsed power were discovered. The data from PBFA-I tests show the flexibility and reliability of pulsed power. This technology base could provide a 100 TW accelerator known as PBFA-II which will be the light ion beam test bed for breakeven experiments for the Department of Energy's Inertial Confinement Fusion Program. Pulsed power technology continues to be flexible and adaptable to a wide variety of basic research problems. It is a cost effective technology for producing large pulsed energy outputs.
