The neutron's electric dipole moment (EDM) has been a subject of interest at least since the late 1940's when the general question of whether, for example, the strong force was invariant under a parity transformation. This led to the first measurement using a modified nuclear magnetic resonance technique that is still used, in one form or another, to measure the neutron EDM. Today, the physics questions are associated with the time reversal violation implied by the existence of a neutron EDM. In this talk, I will focus on a few of the modified techniques used in experiments at ORNL and the ILL, both in the assembly stage, to push the measurement sensitivity an order of magnitude (or two) below the current limit.
