Description
Plasma haloscopes are a novel method for the detection of the resonant conversion of axions to photons. Matching a tunable plasma frequency to the axion mass, allows for resonant conversion even if translation invariance is unbroken. Using a wire metamaterial one can create an artificial plasma, which is tuneable changing the interwire spacing, allowing for large conversion volumes. This talk will give an overview of the plasma haloscope concept and the ongoing efforts of the ALPHA consortium.
