The experimental setup employs a dielectric haloscope consisting of three sapphire disks and a mirror to resonantly enhance the axion-induced microwave signal within the magnetic dipole field provided by the 1.6 T Morpurgo magnet at CERN. Over 14.5 days of data collection, no axion signal was detected. A 95 LB - PUB:(DE-HGF)16 DO - DOI:10.1103/c749-419q UR - https://bib-pubdb1.desy.de/record/639228 ER -
