Solid state modulator applications in linear accelerators

The next generation of linear colliders will require an order of magnitude leap in pulsed power to millions of volts at thousands of amperes, delivered at much higher efficiency than is presently available. The current technology base of thyratrons, PFNs, etc., is inherently limited in scaling to meet these new requirements. Diversified Technologies Inc. (DTI), has had tremendous success since 1993 in the application of high voltage IGBT devices to large, high-voltage and high-current modulator systems. DTI has sold commercial solid-state modulators capable of 20 to 160 kV and 150 to 2000 A for customer applications ranging from RF tube testing to ion-implantation. This technology is rapidly becoming the preferred alternative to conventional vacuum tube modulators and switches for future accelerator designs
