2.4.2.2 Quadrupole Magnets
Table 2.4.14 lists the specifications of the quadrupole magnets used in the Super-FRS. The table is
subdivided into the radiation resistant quadrupole magnets needed for the 1 st dipole stage of the
Pre-Separator and the superferric quadrupole magnets for the 2 nd dipole stage of the Pre-Separator,
the Main-Separator, and the Energy-Buncher. Although all magnets will be operated in a DC mode
the iron design has to be built by laminations since the Bρ setting of the Super-FRS has to be
changed frequently according to the experimental requirements.
