DRAFT<br />
For magnets with less stringent field quality requirements (e.g. correctors and steerer magnets<br />
whose field has only to be known in the range of a percent) it is sufficient to monitor the production<br />
randomly by measuring only one or few magnets (see also section 2.4.A5.1). The different measurement<br />
methods foreseen for the different magnets are summarized in Table 2.4.41. The curvature<br />
of the used search coils for the dipoles is given in Table 2.4.42 and the radius of the rotating coil is<br />
given in Table 2.4.43.<br />
Matching Magnet Length<br />
For machines with only a few dipoles and quadrupoles (e.g. 24 pieces) the length of the magnets<br />
has to be matched. For this purpose laminations are inserted at the end of the yoke. The field of the<br />
magnet has to be remeasured after this operation.<br />
