A 3KG Kicker Magnet System for the Tevatron Beam Abort System

We report on the design of the prototype kicker magnet system to be used in the abort channel of the Tevatron at Fermilab. The magnet has a peak field of 3kG, a 10-90% rise time of 1.5¿s, and the field is greater than 90% of peak for 21¿sec. The kicker magnetic energy is stored in a capacitor and resonantly discharged into the magnet inductance. When the magnet is completely charged a thyratron-ignitron combination is used to clip the recharge of the capacitor and circulate the current in the magnet.
