    Description
At the Paul Scherrer Institut an international collaboration searches for a permanent electric dipole moment of the neutron, which is a sensitive probe for physics beyond the Standard Model. This experiment requires very sensitive magnetometers to correct for systematic errors related to magnetic field fluctuations. We present progress on a co-magnetometer which detects the spin precession frequency of 199-Hg atoms in the same volume as the neutrons. 204-Hg discharge lamps, used so far, are replaced by a new laser system, which results in higher sensitivity of the magnetometer. This work is supported by the SNF under grant 200020_144473.
