Cylindrical Cavity Simulation for Searching Axions

Abstract

The axion is an excellent candidate for cold dark matter. In 1983, Sikivie [1] proposed the scheme to detect axions using a resonant cavity inside a high magnetic field. In order to detect axions in his scheme, we need to scan a range of resonant frequencies of the cavity where the converted photon signal gets enhanced. This poster presents the ways to design a frequency tuning system with conducting and dielectric materials inside the cavity. The simulation software package COMSOL Multiphysics was used to evaluate the effects on the Q-factor and the form factor with different configurations and materials.
