MAGNETIC MEASUREMENT OF THE NSLS-II BOOSTER DIPOLE WITH COMBINE FUNCTIONS

摘要

The magnetic system of NSLS II Booster is designed, manufactured and tested in BINP, Russia. The booster dipole incorporates quadrupole and sextupole components and has rather tight requirement for the field quality ±2·10~(-4) in the good field region ±2 cm. The magnets provide the booster operation in the energy range from 170 MeV to 3.15 GeV with 2 Hz repetition frequency. This report contains description of the magnetic measurement bench and the results achieved for the DC case; AC magnet test including vacuum chamber influence is described in [1].
