2.4.2.4 Steerers<br />

The total beam path of the <strong>Super</strong>-FRS is more than 170 m. Therefore means to correct the beam<br />

position in y-direction is mandatory. Altogether six pairs of y-steerers will be installed in the three<br />

branches of <strong>Super</strong>-FRS. The steerers will be rather short and will be implemented as superconducting<br />

dipole correction coils located between two successive quadrupole magnets.The main<br />

requirements to the <strong>Super</strong>-FRS y-steerers are summarized in Table 2.4.18.<br />
