New High-Dispersion Beamlines at the Bevalac for the Production, Purification and Transport of Radioactive BEAMS

摘要

The external particle beam transport area of the Lawrence Berkeley Laboratory's Bevalac was redesigned so that radioactive beams may be more efficiently analyzed and transported. Using a variety of relativistic heavy ions available at the Bevalac, radioactive beams can be formed at the first external focus point of the accelerator by the process of nuclear fragmentation. The large cross-section and small deflection of the projectile fragments leads to high production and delivery efficiency for these beams. The production, purification, and delivery of radioactive beams of /sup 20,21/F and sup 39 Ca are reported. (ERA citation 12:035494)
