Abstract

A full-scale model of the 1.25-m-long MDSBV (Magnet Decapole Sextupole Bending Vertical) correction magnet for the Large Hadron Collider (LHC) has been constructed and is currently being tested. The model contains the desired dipole and sextupole but not the decapole, which was decided upon later. The magnet was built in a very compact way by placing the dipole coil around the sextupole coil. The two coils were vacuum impregnated and prestressed by shrink--fitted aluminum rings. The design took into account the high positional accuracy requirements for the coils and incorporated manufacturing techniques which are compatible with mass production methods, as approximately 800 of these magnets will be required for the LHC. The model is being tested in liquid helium at a temperature of 4.2 K and will be tested later at 2.0 K. The authors describe the construction, the experience gained during assembly, and the test conditions, and give the first test results
