The Next Linear Collider accelerator proposal at SLAC is developing a high efficiency, highly reliable, and low cost Solid State Induction Modulator for our 500KV, 230A X band klystrons. The induction or fractional turn transformer is most applicable for short pulse width of less than 1.5 microseconds due to the size of the induction cores involved. This paper will cover the techniques SLAC is developing to use the induction modulator in longer pulse operation of up to 15 microseconds. The 3 microsecond SLAC design as will as the proposals for wider pulse application will be discussed.
