Description

  • Content Description: A 22.5 {mu}H, 22.5 m{Omega} transformer septum magnet must be pulsed at a 60 Hz rate to inject beam from a 450 MeV positron linac into a positron accumulator ring (PAR) and to extract beam from it. Of the 60 pulses per second the first 24 are used for injection and the 30th for extraction. The 25th through the 29th are not used. This pattern is repeated continuously. A design study was performed of the power supply proposed in the APS Title I design. This supply produces a pulse that is approximately a half-sine-wave with a base width of approximately 1/3 ms; its peak current is adjustable from 3.5kA to 4.7kA and is repeatable within {+-}0.05%. The septum steel is reset by a half-sine pulse of reverse polarity a few milliseconds after the forward current pulse. No beam is present during reset. The use of the transformer design minimizes the cost of the capacitors used for energy storage.
