Precision Multi-Mode Microwave Spectroscopy of Paramagnetic and Rare-Earth Ion Spin Defects in Single Crystal Calcium Tungstate
Elrina Hartman, Michael E Tobar, Ben T McAllister +2
We present experimental observations of dilute ion spin ensemble defects in a low-loss single crystal cylindrical sample of CaWO cooled to mK in temperature. Crystal field…
Exclusion of ALP Cogenesis Dark Matter in a Mass Window Above 100 eV
Aaron Quiskamp, Ben T. McAllister, Paul Altin +3
We report the results of Phase 1b of The ORGAN Experiment, a microwave cavity haloscope searching for dark matter axions in the eV mass range. The search excludes…
Tunable Rectangular Resonant Cavities for Axion Haloscopes
Ben T. McAllister, Aaron P. Quiskamp, Michael E. Tobar
Axions are a compelling dark matter candidate, and one of the primary techniques employed to search for them is the axion haloscope, in which a resonant cavity is deployed inside a…
Low Frequency (100-600 MHz) Searches with Axion Cavity Haloscopes
S. Chakrabarty, J. R. Gleason, Y. Han +44
We investigate reentrant and dielectric loaded cavities for the purpose of extending the range of axion cavity haloscopes to lower masses, below the range where the Axion Dark Matt…
Searching for Low-Mass Axions using Resonant Upconversion
Catriona A. Thomson, Maxim Goryachev, Ben T. McAllister +3
We present new results of a room temperature resonant AC haloscope, which searches for axions via photon upconversion. Traditional haloscopes require a strong applied DC magnetic b…
