aCORN: A precision measurement of the electron-antineutrino correlation in neutron decay

The aCORN experiment uses a unique method to determine the electron-antineutrino correlation (``a" coefficient) in neutron decay from an asymmetry between fast and slow recoil proton groups. High precision proton spectroscopy, which has limited previous experiments to the 5\% uncertainty level, is not needed. aCORN is now running on the NG-6 neutron physics end position at the NIST Center for Neutron Research (NCNR). The goal of the current run is 2\%. In late 2013 aCORN will be moved to the new high-flux NG-C end position at the NCNR for a second run with a goal of 0.5\%. A brief status report will be presented.
