Modeling and dimensioning of High Voltage pulse transformers for klystron modulators

In linear particle accelerators, klystrons operating in synchronized pulsed mode are used for RF power production and their power supply is provided by modulators that are high voltage and high power pulse generators. One solid state topology of klystron modulator is using a monolithic High Voltage pulse transformer. Future electron-positron linear colliders like the Compact Linear Collider (CLIC) will need a huge number of klystron modulators with tight dynamical specifications and high efficiency for minimizing their power consumption. With such new complex specifications, the feasibility of the modulator topology needs the development of an accurate methodology for the design of High Power & High Voltage Pulse Transformers. This paper presents the first development steps of an optimal design environment of these devices in terms of modeling & dimensioning tools and its applications.
