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…

On operation and control of CW magnetrons for superconducting accelerators
G. Kazakevich, R. P. Johnson, I. Gonin +3
CW magnetrons, developed for industrial RF heaters, were suggested to feed RF cavities of superconducting accelerators due to higher efficiency and lower cost of RF power than prov…

A Precision Gyroscope from the Helicity of Light
Michael A. Fedderke, Roni Harnik, David E. Kaplan +4
We describe a gyroscope that measures rotation based on the effects of the rotation on the polarization of light. Rotation induces a differential phase shift in the propagation of…
