Abstract :
The SLC (SLAC Linear Collider) damping ring extraction kicker magnets require that the magnetic field, 58 ns before extraction, be less than 0.1% of the extraction field. The kicker thyratrons inherently generate prepulse currents of greater than 2%. A kicker prepulse canceler system was developed, which generates a 2.5-kV, 40-ns-wide pulse with 8-ns risetime into 12.5 Omega in such a manner as to cancel the kicker thyratrons´ prepulse current. The prepulse canceler has a drift of less than 5 ns and has a jitter of less than 50 ps RMS.<>
