Today we published a new paper in Physical Review Applied, on an innovative, tunable magnetic shielding system. With the tuned system, we suppress external magnetic field disturbances by up to a factor of 225 ± 15. Together with other developments, this will enable future antiproton-to-proton charge-to-mass ratio comparisons with fourfold reduced frequency fluctuations and antiproton magnetic moment determinations with about tenfold reduced uncertainty.
