DMRadio-Core: A new approach for GUT-scale axion searches
Year: 2026
Type: article
Abstract: Searches for QCD axions with masses in the n eV / c 2 mass range are strongly motivated by new physics at the grand unified theory (GUT) scale and by well-motivated preinflationary axion symmetry breaking scales. This parameter space is challenging to probe due to the small axion-photon couplings, which typically require large, high-field magnets with substantial stored energy. In this paper, we propose a new experimental geometry based on a narrow-bore, segmented solenoid that optimizes the collection of the axion-induced signal using LC resonators outside the high-field region of the magnet bore. This alternative optimization significantly reduces the required stored magnetic energy while preserving sensitivity, thus enabling a near-term experiment in the 30–200 MHz ( 120 − 830 n eV / c 2 ) range, with a cost-effective, staged scaling to a GUT-scale experiment in the 100 kHz–30 MHz ( 0.4 − 120 n eV / c 2 ) range.
