Title: Fast ferroelectric phase shifters for energy recovery linacs

Abstract

Fast phase shifters are described that use a novel barium strontium titanate ceramic that can rapidly change its dielectric constant as an external bias voltage is changed. These phase shifters promise to reduce by ~10 times the power requirements for the rf source needed to drive an energy recovery linac (ERL). Such phase shifters will be coupled with superconducting radiofrequency cavities so as to tune them to compensate for phase instabilities, whether beam-driven or those caused by microphonics. The most promising design is presented, which was successfully cold tested and demonstrated a switching speed of ~30 ns for 77 deg, corresponding to < 0.5 ns per deg of rf phase. As a result, other crucial issues (losses, phase shift values, etc.) are discussed.

Fast 704 MHz Ferroelectric Tuner for Superconducting Cavities

Technical Report Hirshfield, Jay L

The Omega-P SBIR project described in this Report has as its goal the development, test, and evaluation of a fast electrically-controlled L-band tuner for BNL Energy Recovery Linac (ERL) in the Electron Ion Collider (EIC) upgrade of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL). The tuner, that employs an electrically-controlled ferroelectric component, is to allow fast compensation to cavity resonance changes. In ERLs, there are several factors which significantly affect the amount of power required from the wall-plug to provide the RF-power level necessary for the operation. When beam loading is small, the power requirements aremore »« less

Fast high-power microwave ferroelectric phase shifters for accelerator application

Conference Kazakov, S.Yu. ; Shchelkunov, S. V. ; Yakovlev, V. P. ; ... - AIP Conf.Proc.

Measurements are reported for a one-third version of a high-power L-band ferroelectric phase shifter. This phase shifter is designed to allow rapid adjustments of cavity coupling in an accelerator where RF source fluctuations, microphonics, or othe r uncontrolled fluctuations could cause undesired emittance growth. Experimental measurements of phase shift vs externally-applied voltage, insertion loss, and switching speed are presented. An average switching rate of less than 0.5 ns for each degree of RF phase has been measured.

Fast Switching Ferroelectric Materials for Accelerator Applications

Journal Article Kanareykin, A ; Schoessow, P ; Nenasheva, E ; ... - AIP Conference Proceedings

Fast switching (<10 nsec) measurement results on the recently developed BST(M) (barium strontium titanium oxide composition with magnesium-based additions) ferroelectric materials are presented. These materials can be used as the basis for new advanced technology components suitable for high-gradient accelerators. A ferroelectric ceramic has an electric field-dependent dielectric permittivity that can be altered by applying a bias voltage. Ferroelectric materials offer significant benefits for linear collider applications, in particular, for switching and control elements where a very short response time of <10 nsec is required. The measurement results presented here show that the new BST(M) ceramic exhibits a high tunabilitymore »« less

New Low-Loss Ferroelectric Materials for Accelerator Applications

Journal Article Kanareykin, A ; Nenasheva, E ; Karmanenko, S ; ... - AIP Conference Proceedings

We present results on a new ferroelectric material based on bulk low-loss BST (Barium-Strontium Titanium oxides) compounds especially developed for accelerator applications. We have demonstrated suitable nonlinear dielectric properties of this material that make it useful for switching and tuning RF accelerator components. The material exhibits a dielectric constant of 400-500 and tunability factor of 1.2. The best sample of those studied demonstrated a loss factor <4x10-3 at 35 GHz. Ferroelectric rings and substrates are key components required for electrically controlled switches and phase shifters for active pulse compressors for future linear colliders.

Beam Line Design and Beam Physics Study of Energy Recovery Linac Free Electron Laser at Peking University (in Chinese)

Thesis/Dissertation Wang, Guimei

Energy recovering linac (ERL) offers an attractive alternative for generating intense beams of charged particles by approaching the operational efficiency of a storage ring while maintaining the superior beam quality typical of a linear accelerator. In ERLs, the decelerated beam cancels the beam loading effects of the accelerated beam with high repetition rate. Therefore, ERLs can, in principle, accelerate very high average currents with only modest amounts of RF power. So the efficiency of RF power to beam is much higher. Furthermore, the energy of beam to dump is lower, so it will reduce dump radiation. With the successful experimentsmore »« less
