Interaction of degenerate higher order modes in periodic SRF accelerating structures
Vyacheslav Yakovlev, Sergey Belomestnykh, Timergali Khabiboulline +1
The paper considers the effect of degenerate higher-order mode (HOM) interaction, which may lead to the formation of trapped modes with high shunt impedance. Methods for eliminatin…
Cryogenic RF characterization of the MAGO cavity for high-frequency gravitational-wave detection
Can Dokuyucu, Bianca Giaccone, Tom Krokotsch +13
Superconducting radio-frequency (SRF) cavities are promising resonant sensors for gravitational-wave detection in the kHz-MHz frequency range. We report the cryogenic RF characteri…
Detection of high-frequency gravitational waves using SRF cavities
M. Wenskat, B. Giaccone, J. Branlard +21
Today, apart from some isolated R&D efforts, there are no gravitational wave (GW) experiments, yet which explore a large part of the vast frequency range above the LIGO/Virgo band.…
Improved Dark Photon Sensitivity from the Dark SRF Experiment
Saarik Kalia, Zhen Liu, Bianca Giaccone +15
We report the refined dark-photon exclusion bound from Dark SRF's pathfinder run. Our new result is driven by improved theoretical modeling of frequency instability in high-quality…
Excellent performance of 650 MHz single-cell niobium cavity after electropolishing
V. Chouhan, D. Bice, A. Cravatta +6
Electropolishing process and cathodes have undergone modification and optimization for both low- and high-beta 650 MHz five-cell niobium cavities for PIP-II. Cavities treated with…
