Design of new resonant haloscopes in the search for the darkmatter axion: a review of the first steps in the RADES collaboration

TL;DR

This review summarizes the RADES collaboration's first five years of developing resonant haloscopes with multi-cavity designs to enhance dark matter axion detection sensitivity, including design evolution, data acquisition, and initial experimental results.

Contribution

It provides a comprehensive overview of innovative multi-cavity haloscope designs and their development for improved axion detection in dipole and solenoid magnets.

Findings

Initial designs increased haloscope volume and sensitivity.

Successful first experimental run conducted.

Future plans for both dipole and solenoid magnet experiments.

Abstract

Within the increasing interest in the dark matter axion detection through haloscopes, in which different international groups are currently involved, the RADES group was established in 2016 with the goal of developing very sensitive detection systems to be operated in dipole magnets. This review deals with the work developed by this collaboration during its first five years, from the first designs, based on the multi-cavity concept, aiming to increase the haloscope volume and, so, to improve its sensitivity, their evolution, the data acquisition design, and, finally, the first experimental run. Moreover, the envisaged work within RADES, for both dipole and solenoid magnets, in the short and medium term is also presented.
