A Slow Extracted Beam for the Cornell 2 GeV Synchrotron

The electron beam at the Cornell 2 GeV synchrotron has been extracted using independently controlled quadrupole and octupole magnets. The septum used has sufficient bend to avoid the synchrotron fringe field. The extracted beam has a divergence of less than 0.5 mrad., a size of 2 mm x 2 mm, a momentum spread less than 0.25% and an intensity greater than 109 electron/pulse (30 pulses/second. The beam is stable, easy to obtain and parasitic operation is possible.
