3He gas handling system and RF discharge for optical pumping

Abstract

Axions are hypothetical pseudo scalar particles that appear in the solution of the strong CP problem. Axions can also be a dark-matter candidate if their mass is in light regime. Many of these haloscope experiments to detect axions are based on this assumption. In addition, Moody and Wilczek postulated an interaction between monopole and dipole masses that can be mediated by axions at macroscopic scale [1]. We propose new experiment that can detect axions by measuring by pseudo-magnetic field induced between monopole and dipole. For this experiment, we have developed 3He polarization system using metastable exchange optical pumping (MEOP) technique.
