TI - The axion dark-matter eXperiment: Results and plans IS - DESY-PROC-2011-04 CY - Hamburg PB - Deutsches Elektronen-Synchrotron, DESY M1 - PUBDB-2016-01074 M1 - DESY-PROC-2011-04 SP - 47-50 PY - 2011 AB - The axion affects issues of the origin of CP symmetry in the strong interactions and the composition of the dark matter of the universe. Current constraints limit its mass to 1 μeV-10 meV, with the low end of this range (1-10 μeV) especially significant for dark-matter axions. Axions may be detected by their coupling to photons in a resonant cavity in a strong magnetic field. The Axion Dark-Matter eXperiment (ADMX) recently completed Phase I of an upgrade to its detector, incorporating SQUID electronics in the receiver front end and conducting a year-long data run. Phase II of the upgrade will install a high-capacity dilution refrigerator to cool the SQUID and cavity to ∼ 100 mK.
