Abstract

The injector for the BESSY storage ring is an 800 MeV synchrotron with a 20 MeV microtron as preinjector mainly manufactured by Scanditronix AB. The synchrotron was designed as a separated function machine. The bending magnets, the focussing and the defocussing quadrupoles are powered by three independent Whitecircuits. These circuits are phase-locked to each other via a microprocessor. The repetition rate of the synchrotron is 10 c/sec. The max. extracted current measured at 570 MeV was 12 mA/50 ns. The emittance was ε _x 1.6 × 10 ^-6 πm rad, ε _y = 0.25 × 10 ^-6 πm rad. The energy was changed to 776 MeV in August 1982. The extracted current was 7 mA/50 ns.
