Abstract

KEK has completed 13 of the 18 MQXA quadrupole magnets supplied for the LHC interaction region. The field measurements at room temperature were performed before and after the cold test. The multipole components by the warm measurements showed a good correlation with those by the cold measurements. It is concluded that field quality of the magnets can be evaluated by the warm measurements.
