Radiological dose calculations for the particle beam fusion accelerator upgrade (PBFA-U)
- Univ. of Wisconsin, Madison, WI (United States)
PBFA-U is a proposed upgrade version Particle Beam Fusion Accelerator (PBFA-II) facility currently operating at Sandia National Laboratory. PBFA-U is an ignition facility which is to be used for performing research on light ion beam driven inertial confinement fusion. The facility will explode targets inside a 1 m radius chamber. Targets at the center of the chamber are imploded by energetic light ions (4.5 MJ). The new facility is expected to operate for 10 years during which three different types of experiments are proposed; beam diagnostic gas filled and cryogenic target implosion. Beam diagnostic shots are expected during the first 5 years of operation at a rate of 500 shots/year. No neutrons are produced during these shots. However, each shot produces 320 kJ of bremsstrahlung radiation which is produced by energetic electrons in the diode region. Shots on the gas-filled targets during the following 3 years of operation would result in a fusion neutron yield of 20 kJ per shot. The proposed operation schedule for the gas-filled targets also assumes 500 shots/year. Shots on the cryogenic targets (fusion shots) are performed during the final 2 years of operation at a rate of 250 shots/year. Each shot would result in a fusion neutron yield of 20 MJ. Similar to the beam diagnostic shots, shots on gas-filled and cryogenic targets results in a production of 320 kJ of Bremsstrahlung radiation. {gamma}-rays from the Bremsstrahlung radiation results in emitting photoneutrons from the diode structure.
