Abstract
We report on the first axion search results from the Cryogenic Dark Matter Search (CDMS) experiment at the Soudan Underground Laboratory. An energy threshold of 2 keV for electron-recoil events allows a search for possible solar axion conversion into photons or local galactic axion conversion into electrons in the germanium crystal detectors. The solar axion search sets an upper limit on the Primakov coupling g_(aγγ) of 2.4×10^(-9) GeV^(-1) at the 95% confidence level for an axion mass less than 0.1 keV/c^2. This limit benefits from the first precise measurement of the absolute crystal plane orientations in this type of experiment. The galactic axion search analysis sets a world-leading experimental upper limit on the axioelectric coupling g_(ae[overbar]e) of 1.4×10^(-12) at the 90% confidence level for an axion mass of 2.5 keV/c^2.

© 2009 American Physical Society. Received 5 March 2009; published 1 October 2009. This experiment would not have been possible without the contributions of numerous engineers and technicians; we would like to especially thank Larry Novak, Richard Schmitt, and Astrid Tomada. We thank the CAST and Tokyo helioscope collaborations for providing us with their axion limits. The direction measurement of the true north in the Soudan Underground Laboratory relied on the help from the Fermilab Alignment Group. Special thanks to Virgil Bocean.
