Separators for SLAC B-Factory

In order to separate the beams during injection, a closed vertical bump will be introduced in the B-Factory High Energy Ring (HER) using four dedicated, pulsed magnets. measurements. The design field in the magnets is B₀ = 660 G; the field integrals of the magnets are nominally: (Integral) Hdl = 0.0450 T.m; (Integral) Hdl = 0.0420 T.m; (Integral) Hdl = 0.0756 T.m; (Integral) HDL = 0.0832 T.m The magnet apertures are 15 cm horizontal along the field direction and 10 cm in the vertical direction. The beams will be separated with a rise time of about 200 ms at the end of a coast and brought back into collision within about 1 ms. The magnets have been made and tested successfully at BINP and at SLAC. The whole system including pulsed power supply and shunts were also tested successfully.
