A Coreless Approaches for ON/OFF Marx Type Modulators

Summary form only given. SLAC was first to report using ON/OFF switches in Marx type modulator [1]. The development of Marx type modulator was bounded with the NLC need [2]. The high energy physics runs based on the ILC concept where longer modulator pulse width is required. The SLAC idea of coreless modulators was useful for other applications and accelerator technologies. The discussed conception is presented as a continuation of the earlier published articles. Several types of the Marx ON/OFF type modulators are under consideration. This article describes the new coreless approach, based on the solid state ON/OFF Marx´s topology. Further integration of the ON/OFF Marx type modulator and its power supply is proposed. Two topologies are under consideration. The first scheme is an integration of DC/DC converters with ON/OFF Marx. The second topology is based on the usage of AC network directly with ON/OFF Marx scheme. An AC high voltage network feeds individual Marx´s cells through the inductive and diode assemblies.
