Abstract
The Light Ion Fusion Target Development Facility (TDF) is expected to test approximately ten targets per day having yields in the 50 to 800 MJ range. This large number of high yield micro-explosions creates design problems in the TDF that are not present in PBFA-I and PBFA-II. The TDF would be the first light ion facility where radioactivity in the target debris and induced in the facility itself constitute a biological hazard. It must have a first wall and a target diagnostics package that can survive repeated mechanical and thermal pulses from the target microexplosions. In addition, the repetition rate is much higher than for present day light ion beam drivers. A preliminary conceptual design for the TDF including a reaction chamber, biological shield, target diagnostics package and driver that addresses these and other problems is presented.
