The Cosmic Axion Spin Precession Experiment (CASPEr) is a direct
Axion Like Particle (ALP) search. We use techniques analogous to Continuous Wave (CW)
Nuclear Magnetic Resonance to set limits on the axion-nucleon coupling.
The axion field can exert a torque on nuclear spins either by the axion wind
effect or by inducing a time-varying Electric Dipole Moment (EDM) in the nucleon.
We here report on the progress of the construction of the CASPEr-wind apparatus,
and discuss anticipated sensitivity.
