Abstract :
The Efremov Institute and DESY have designed in collaboration high performance normal conducting septum half-quadrupole magnets for the HERA luminosity upgrade. These magnets of the type GM have a length of 3.4 m. The 85 mm thick vertical mirror plate is cut out near the origin to provide a septum of 5 mm thickness. By this way a virtually field free space allows the passage of the separate e-beam very close to the high gradient field region.
