Magnetic measurement data of the injector synchrotron dipole magnets for the 7-GeV Advanced Photon Source.

摘要

The magnetic measurement data of the first 34 of the required 68 production magnets for the injector synchrotron are summarized. The magnetic measurement method of the field strength and field shape relative to a reference magnet is described. The standard deviation of the integrated field strength for the 34 magnets is 3.3 (times) 10(sup (minus)4) and the variation of the integrated field with transverse displacement of (+-)25 mm is less than 2.5 (times) 10(sup (minus)4).
