- 요약Searches for the electron electric dipole moment (eEDM) sensitively probe for physics beyond the Standard Model that are time-reversal violating interactions. The ACME Collaboration increased the eEDM sensitivity by a factor of 100 six years ago, and a recent measurement by the JILA eEDM group increased the sensitivity by an additional factor of 2.5, to |de| 4.1x10−30 e·cm. The third generation of the Advanced Cold Molecule Electron EDM experiment (ACME III) aims to enhance the sensitivity to the electron EDM by more than an additional order of magnitude. A critical challenge in ACME III is the precise control of the magnetic fields and gradients that significantly influence both systematic and statistical uncertainties. The described design, construction and performance of a magnetic shield and field coil achieves a residual magnetic field below 10 µG and field uniformity better than 1 µG/cm as of this writing, without residual magnetization building up caused by magnetic fields that must be produced and reversed in the shielded volume. This apparatus, combined with a longer coherence time and an increased signal, position ACME III to probe new physics at energy scales of tens of TeV, comparable and even well above the reach of the Large Hadron Collider (LHC).
