The theory and operation of a device that makes the beam in the Cosmotron come onto a target in about 5 &mgr;sec instead of the usual 3 msec are described. The magnetic field in a two‐turn coil, pulsed with a condenser bank, deflects the internal beam enough to throw the beam onto a target during the rise time of the perturbing field. The system has an inductance of 2 &mgr;h and a capacitance of 11 &mgr;f, giving a ringing frequency of 34 kc, a peak current of 47 000 amp at 20 kv and a peak field of 1100 gauss. The ejector can also be used to put only a small fraction of the beam onto a target, permitting the rest of the beam to continue on the normal accelerating cycle.
