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 3D CAD model has been developed by LBNL
  incorporating the ICST coupling coil model
