Abstract

The QTG quadrupole magnets will be a part of the CERN Neutrino to Gran Sasso (CNGS) transfer line. 23 QTG magnets will be used as lattice and matching quadrupoles. They are being produced in the framework of a German in-kind contribution via DESY to CNGS. The QTG magnets have a maximum gradient of 40 T/m at the 530 A excitation current and are manufactured from laminated steel cores. The yoke length is 2.2 m and the inscribed radius is 22.5 mm. The excitation coils are made of vacuum impregnated hollow copper conductor. The main design aspects and the results of the acceptance tests including mechanical, electrical and magnetic field measurements are described.
