TL;DR: The axion-photon coupling strength of the CERN Axion Solar Telescope (CAST) was shown to be at least 0.02$ eV in the first vacuum phase (2003-2004) with low-background x-ray detectors and a new xray telescope as mentioned in this paper.

TL;DR: In this paper, the authors reported results from CAST with evacuated magnet bores (phase I), setting limits on lower mass axions, and they also reported results of CAST Phase II, where the magnetbores were filled with 4He gas (phase II) of variable pressure.
