New final focus system for the SLAC Linear Collider

The final focus system of the SLC (Stanford Linear Collider) has been upgraded by replacing the final quadrupole magnets with higher-gradient superconducting magnets positioned closer to the interaction point. The parameters of the new system have been chosen to be compatible with the SLD detector with a minimum of changes to other final focus components. Commissioning plans for the new system are also presented. >
