Radiation aspects of the B-Factory at SLAC
Conference
·
OSTI ID:491610
The B-Factor is a high-energy physics project at SLAC that studies the phenomenon of CP violation from collisions between two stored beams; high energy electrons (HER, maximum 12-GeV) and low energy positrons (LER, maximum 4-GeV). Both the HER and LER are located in an underground tunnel of 2,200-m-long circumference with a maximum stored current of 3 A. The injector consists of the existing SLAC 2-mile-long LINAC with two extraction and transport lines for both rings. Radiation aspects of the machine are addressed in the context of machine protection and personnel protection. Specific illustrations (e.g., the estimations of neutron, photon and synchrotron radiation environment in the ring tunnel and the radiation levels outside a typical Interaction Region, etc.) are given to show a few natures of the radiation issues for the B-Factory and to reflect the appropriate SLAC policies on radiation safety.
