CM-AMO Seminar | Optical Magnetometry: Quantum Sensing and Absolute Magnetometry Challenges the Standard Model

Tim Chupp (U-M Physics)

Sensitive and accurate detection of time dependent magnetic fields has myriad applications from fundamental physics to astronomy to medicine to geophysics and, of course, to defense. Motivated by two experiments that challenge the Standard Model of Elementary particle physics, we have developed new approaches to magnetometry using optically pumped 3He applied from Tesla to microTesla. For the recently announced new measurement of the muon magnetic moment anomaly at Fermilab, an absolute 3He NMR magnetometer accurate to 30 ppb was introduced into the calibration chain of the 1.45 T magnetic field of the storage ring. For experiments under development to extend sensitivity to the neutron electric dipole moment, 3He magnetometers provide "read out" by micro-fabricated rubidium optical magnetometers. I'll describe the motivations and our continuing efforts to develop and improve these sensors.
