The B-Factory is a primary component of the BaBar experiment being conducted at the Stanford Linear Accelerator Center, in collaboration with Lawrence Berkeley Laboratory and Lawrence Livermore National Laboratory, the purpose of which is to study the natural explanation for CP violation by the complex phase in the CKM matrix.
The B-Factory achieved its first collisions in July 1998, and the system went active in May 1999. It is powered by the PEP-II positron-electron linear collider. The accelerator is run asymmetrically, with the High Energy Ring, reusing the tunnel and dipole magnets of the old PEP machine, providing the electron beam at 9.0 GeV, and the comparitively new Low Energy Ring providing the positron beam at 3.1 GeV. Both rings use room temperature RF, with cooper cavities and waveguides. About 4 nanoseconds elapse between the head-on collisions of each bunch of particles.
