First Look into the Potential of the Proton Spin in a Quasi-Frozen Spin Lattice as an Axion Detector

The work presents preliminary results of a theoretical analysis and modeling of proton spin sensitivity in a quasi-frozen spin lattice, used as a broadband axion antenna, with an emphasis on the constraints from the axion field local phase coherence time and the polarized beam spin coherence time. Three major topics include: axion field resonance conditions; the proposal to use (quasi-)frozen spin technologies to improve the axion field local phase coherence time; the impact of sextupole fields used to improve the beam spin coherence time.
