Description
An improved detection scheme for a light-shining-through-wall (LSW) experiment for axion-like particle searches is introduced. Extremely intense photon fluxes (from 100 kW to 1MW) from sources at frequencies in the sub-THz range are sent in an intense magnetic field where a photon to axion-like particle conversion is possible. A single photon detector in this frequency domain based on a superconducting phase transition edge sensor is proposed. High quality factor Fabry-Perot cavities in the microwave domain (Q ≈ 104-105), both on the photon-axion conversion and photon regeneration side are used to increase the sensitivity.
The present exclusion limits based on laboratory experiments for axion-like particles searches might be improved by at least four orders of magnitude for axion masses ≤ 0.01 meV.
