摘要：
The corrector magnet for the Large Hadron Collider (LHC) contains a 1.5 tesla dipole for orbit correction and a 8000 T/m(2) sextupole for chromaticity correction. The dipole has for compactness been mounted around the sextupole coil. A full scale prototype of 1.3 m length has been fabricated and tested. The coils were first tested at 4.2 K. It appeared that the training of the impregnated coils could be strongly reduced by increasing the radial pre-compression. The coils were subsequently cooled to the operational temperature between 1.8 and 2 K and the field quality was measured with a harmonic rotating coil. The paper presents the results of these tests and the experience obtained with such a type of combined magnet.
