Coupling Coil Integration Topics • A revised coupling coil design has been developed by LBNL and ICST at Harbin, China • The coil length has increased from 250 to 285 mm, resulting in a longer coil vacuum vessel • New design affects access to cavity ports (RF, vacuum and diagnostic) and tuner connections • Magnetic forces must be transmitted from the cold mass support cones to the vacuum vessel • A new 3 D CAD model has been developed by LBNL incorporating the ICST coupling coil model Coupling Coil Integration with the RFCC Module Steve Virostek - Lawrence Berkeley National Lab 3
