Pulsed ironfree inflectors for particle injection and extraction in cyclic accelerators

The layout of beam extraction from a cyclic accelerator using a pulsed septum magnet is presented. The magnetic field pulse duration is about 10 μs; the amplitude is about 1 T. The conceptual design of the septum and the power-supply circuit are described. The power-supply pulse generator provides a current of about 100 kA in the current loop with an inductance of 1 μH.
