A meeting is being held at Oak Ridge National Laboratory (ORNL) on October 20 and 21, 2022, to introduce the ALPHA (Axion Longitudinal Plasma HAloscope) experiment currently in the R&D and preliminary design stage.

The ALPHA experiment is based on the concept of using a metamaterial resonator in lieu of a conventional microwave cavity, capable of reaching much higher frequencies in a large volume format, corresponding to predictions for the mass of the post-inflation axion.  Theoretical and experimental work by the ALPHA R&D consortium over the past three years has been very encouraging, and has prepared for the transition to a full-scale experiment. ORNL is in the process of procuring a large volume 13-Tesla magnet from the Helmholtz-Zentrum Berlin, developed by the National High Magnetic Field Laboratory in Tallahassee, for use in this experiment.
