Accelerator Research & Coordination at Argonne
Rich history beginning with ZGS, continuing to IPNS, ATLAS, and APS, accumulating leading expertise in accelerator physics and enabling technology An effort to coordinate accelerator research at various Argonne divisions was initiated by CARA in 2002 For more effective coordination, Argonne Accelerator Institute was launched in March 2006 Several new projects under study – APS2, RIA/Exotic Beam Facility, VCNS, ILC

Opportunities for Large Accelerator Projects in the Chicago Region
Argonne: operating the APS, currently the brightest xray facility, working towards APS2 Fermilab: operating Tevatron, currently the highest energy machine, probable site for ILC Strong Argonne-Fermilab collaboration is mutually beneficial; they are within 35 minutes commuting distance MOU between Argonne and Fermilab for collaboration on accelerator research signed on April 21, 2006 Governor Blagojevich proclaimed April 21 as Particle Accelerator Day in Illinois

EP for ILC SCRF Cavities at Argonne
Electro-polishing is the ILC baseline process for SCRF cavities specified for performance at accelerating gradient=35 MV/m and Q=1010 The ATLAS group at Argonne is nation’s foremost expert in EP through their pioneering development of low beta SCRF structures Argonne is constructing a pre-production EP facility at the new Argonne-Fermilab Joint Surface Processing Facility
