The magnet system for the BESSY II injector synchrotron

Injector for the 3/sup rd/ generation synchrotron light source BESSY II is a 1.9 GeV full energy 10 cps rapid cycling synchrotron. The 96 m circumference FODO lattice consists of 16 cells having one H-type dipole and the F and D quadrupole magnets on a common girder. A complete pre-series cell has been manufactured by the Budker Institute of Nuclear Physics (BINP), Novosibirsk. Detailed investigations of the field quality were performed at BINP as well as at BESSY.
