Unconventional wound glass capacitor component for Power Modulator in RF Accelerator

Radio frequency (RF) technology is a key technology common to all high energy accelerators. RF sources with improved efficiency and accelerating structures with increased accelerating gradient are important for keeping the cost down for future machines. Energy storage components represent a significant part of the cost, volume, and weight of the RF power modulators and high energy density components are highly desirable. We propose to develop advanced wound capacitors with a specialty flexible ultrathin glass with high dielectric constant, low dielectric loss, high thermal stability, and high breakdown strength. The capacitors will combine ultrahigh energy density, high energy efficiency, and low-cost commercial manufacturability. Prototype energy storage device will be designed and fabricated in the nine- month Phase I project. The device will meet the Technology Readiness Level (TRL) of 4. The prototype device will be evaluated based on the specifications of the RF power modulator. Commercial Applications and Other Benefits: The high energy density energy storage device can also be used in other pulsed power systems such as medical defibrillators, military directed energy weapons, and power conditioning systems such as hybrid electric vehicles and smart grids.
