Abstract

Recent theoretical advancements have made the QCD axion a stronger dark matter candidate, especially in the sub-$\mu$eV range. While cavity haloscopes have made significant progress in excluding QCD axions in the $1-100\ \mu\text{eV} $ region, the $1 \text{ peV}- 1\ \mu\text{eV}$ region remains unexplored. The DMRadio program consists of a series of experiments designed to probe low mass axions. DMRadio-50L uses a 1 T average field toroidal magnet and a high-Q LC-oscillator with target sensitivity to axions of $g_{a\gamma\gamma} < 5 \times 10^{-15}\text{ GeV}^{-1}$between 5 kHz and 5 MHz. DMRadio-m$^3$ consists of a higher frequency LC-oscillator in a 4 T peak field solenoidal magnet with sensitivity to the DFSZ model of QCD axions between 30 MHz and 200 MHz. In this work, we present the status of DMRadio-50L and DMRadio-m$^3.$

Report

In this proceeding authors are presenting the status of DMRadio program, particularly of 50L and m^3, looking for QCD axions. DMRadio-50L is about to be finally assembled in summer 2023 and the design of Radio-m^3 is completed. The manuscript is clearly written and well organised. It is also suitably formatted for publication.
I recommend the manuscript for publication after some minor corrections:

Requested changes

- Fig.1 please explain all colours.
- Is there is a plan to set also limit for the N-body model?
- “testbed … for novel …” three times in the test. Maybe one can find an alternative?
