A Tunable Metamaterial Prototype Resonator for ALPHA

Oral-In-person

Abstract

The University of California, Berkeley, is prototyping a metamaterial resonator for ALPHA (Axion Longitudinal Plasma HAloscope) to search for post-inflationary axions, which are motivated by recent theoretical predictions. The metamaterial resonator consists of a lattice of thin copper rods. The plasma frequency of the metamaterial resonator can be tuned by moving the rods in unison using a reciprocal motion tuner. The resonator can be tuned from roughly 12 - 17 GHz. In this talk, I will describe the simulation and initial results of the prototype
