%X Abstract—The electron beam of the European XFEL will beaccelerated to an energy up to 17 GeV in a linear acceleratorwhich is divided into 101 modules. Each module will be equippedwith eight superconducting cavities and a superconductingmagnet package. That package consists of a main superferricquadrupole and two nested corrector dipoles, horizontal andvertical, enclosed in a stainless steel vessel. Conduction cooledcurrent leads are used.Up to four prototypes were produced between 2005 and 2009.Some problems were detected which may complicate the seriesproduction, mainly that the wire diameter was too small for thewinding process, the solid iron yoke was too expensive to bemachined and the magnetization effects on the magnet transferfunction were too high. Therefore, it was decided to revisit thedesign to ease fabrication. The new magnet design is presented inthis paper. The fabrication process and test results of theprototype are reported as well.Finally, the helium vessel around the magnet needs to satisfythe European Standard for Pressure Vessels, namely PED97/23/EC. This paper also describes the modifications necessaryin the original design to achieve that specification.
