The Search for Axion Dark Matter

Dec 1 2015

The Cosmic Axion Spin Precession Experiment (CASPEr) has received funding for phase 1 from the Heising-Simons and Simons Foundations.  CASPEr is designed to detect axion dark matter over a broad range of masses that are unreachable by other techniques.  Proposed by physicists at SITP and collaborators, CASPEr uses the technologies of nuclear magnetic resonance (NMR) and high precision magnetometry to probe axions arising from the highest energies, around fundamental scales such as the grand unification (GUT), string, and Planck scales.  CASPEr is now under construction at Boston University and Johannes Gutenberg University in Mainz.
