Superconducting Magnet Group in KEK for
LHC Low-beta Quadrupole at Interaction Regions

In the framework of the collaboration program between CERN and KEK for the Large Hadron Collider (LHC), KEK is responsible for production of eighteen superconducting quadrupole magnets (MQXA) include spares for the low-beta triplets at four beam interaction regions. After the developments of five 1 meter long magnets and two prototype magnets, the production of MQXA has been started in 2001.
