Improved shielding calculations for the Particle Beam Fusion Accelerator PBFA II
The Sandia National Laboratories Particle Beam Fusion Accelerator PBFA II is expected to produce significant bremsstrahlung on every shot during 30 MV operation. Shielding specific electronic components from the intense bremsstrahlung environment is an important consideration. The authors describe new 3-D Monte Carlo electron-photon transport simulations of the PBFA-II facility that include a more efficient version of the next-event-estimator calculation and final design information for accelerator components within the vacuum chamber. The improved bremsstrahlung shielding analysis is compared with pin diode and thermoluminescent dosimetry measurements obtained during the first four months of accelerator testing.
