Improved shielding calculations for the particle beam fusion accelerator PBFA II

Conference ·
OSTI ID:5876015

PBFA II is a 36-module particle beam fusion accelerator at Sandia National Laboratories that became operational in December 1985. A cutaway drawing of the accelerator is shown. The accelerator has about 3.5 times the energy and power of PBFA I, a 36-module accelerator in operation since June 1980. The most significant difference between the two accelerators, however, is the much higher machine voltage on PBFA II (30 MV instead of 2 MV). The 30-MV voltage will facilitate focusing of heavier ions, such as lithium and carbon, to a fusion target. Some shielding considerations are described.
