At the heart of the new MESA accelerator in Mainz lies this 21-ton superconducting magnet. It will enable precision studies of a fundamental parameter of the #StandardModel, and explore nuclear forces critical to understanding #NeutronStars #PrecisionPhysics #NuclearPhysics

Feasibility study demonstrates quantum logic spectroscopy achieves 10 kHz precision on He+ 1S-2S transition (40.81 eV) using trapped ions and frequency combs, enabling tests of QED and improved fundamental constant measurements.
