Design study of 45-mm bore dipole magnet for 11 to 12 tesla field

PDF Version Also Available for Download.

Description

Two designs of 45mm bore dipole magnets are described about their magnetic characteristics. The first one has a 25mm thick collar with overall diameter of 520 mm. The other one has a 9-mm thin spacer with the overall diameter of 434 mm. Both of them have good field regions of 10{sup -4}, 28 mm wide horizontally and 24 mm wide vertically. With further adjustment of higher harmonics, the good field region can be horizontally increased to 33 mm. With the installation of a beam screen, the estimated vacuum space available for the beam operation is 33 mm wide horizontally and ... continued below

Description

Two designs of 45mm bore dipole magnets are described about their magnetic characteristics. The first one has a 25mm thick collar with overall diameter of 520 mm. The other one has a 9-mm thin spacer with the overall diameter of 434 mm. Both of them have good field regions of 10{sup -4}, 28 mm wide horizontally and 24 mm wide vertically. With further adjustment of higher harmonics, the good field region can be horizontally increased to 33 mm. With the installation of a beam screen, the estimated vacuum space available for the beam operation is 33 mm wide horizontally and 22 mm wide vertically. If we assume that the total degradation of short sample data is 18.5%, the maximum central field values at quench current will be between 11.3 and 11.5 T.
