Abstract

Development of the LHC low-β insertion quadrupole magnet is in progress at KEK since 1995 as a cooperative program between CERN and KEK. Five 1-m short model magnets have been fabricated and three of them have been tested. From the various test results of the first two models, the coil configuration was further optimized to reduce the higher magnetic field harmonic coefficients. The cold test of the third model showed satisfactory performances of the field harmonics. After this R & D work, we are on a stage for fabrication of two prototype magnets which have the same scale as the production magnets. The status of the R & D for the LHC low-beta insertion quadrupole magnet at KEK is described.
