A new lattice design for the NLC positron pre-damping ring

PDF Version Also Available for Download.

Description

The positron source for the Next Linear Collider (NLC) will produce a beam larger than the acceptance of the main damping rings, which are optimized for low extracted emittance. A pre-damping ring, with large acceptance, is therefore needed to reduce the emittance of the beam from the source, so it can be accepted by the main damping ring with minimal particle loss. Previous designs, based on a racetrack structure with TME cells in the arcs, have proven difficult to tune for the required dynamic aperture, in part because of the low symmetry. We report here on a new design, with ... continued below

Description

The positron source for the Next Linear Collider (NLC) will produce a beam larger than the acceptance of the main damping rings, which are optimized for low extracted emittance. A pre-damping ring, with large acceptance, is therefore needed to reduce the emittance of the beam from the source, so it can be accepted by the main damping ring with minimal particle loss. Previous designs, based on a racetrack structure with TME cells in the arcs, have proven difficult to tune for the required dynamic aperture, in part because of the low symmetry. We report here on a new design, with a 10-fold symmetric DBA structure, which meets the principal parameter specifications, and has much greater tuning flexibility.
