Chromaticity corrections in the SLC final focus system

The current technique of measuring the IP (interaction point) chromaticities in the SLC final focus system is presented. A semiempirical correction scheme has been successfully implemented to control the IP chromaticities, as characterized by the waist position dependence on the beam energy to better than 0.5 cm/100 MeV. Several outstanding issues needing further improvement are identified, and possible courses of efforts in the near future are discussed.<
