Probe-assisted Depopulation Pumping in Low-pressure Alkali-metal Vapor Cells for Magnetometry

M. E. Limes, J. Smoot, J. Perez +4

For precision atomic magnetometry, inert buffer gas is included in alkali-metal vapor cells to significantly broaden hyperfine transitions, which facilitates optical pumping and re…

Femtotesla nearly quantum-noise-limited pulsed gradiometer at Earth-scale fields

V. G. Lucivero, W. Lee, M. V. Romalis +3

We describe a finite fields magnetic gradiometer using an intense pulsed laser to polarize a Rb atomic ensemble and a compact VCSEL probe laser to detect paramagnetic Farada…

Heading errors in all-optical alkali-vapor magnetometers in geomagnetic fields

W. Lee, V. G. Lucivero, M. V. Romalis +3

Alkali-metal atomic magnetometers suffer from heading errors in geomagnetic fields as the measured magnetic field depends on the orientation of the sensor with respect to the field…

Femtotesla direct magnetic gradiometer using a single multipass cell

V. G. Lucivero, W. Lee, N. Dural +1

We describe a direct gradiometer using optical pumping with opposite circular polarization in two Rb atomic ensembles within a single multipass cell. A far-detuned probe las…

Portable magnetometry for detection of biomagnetism in ambient environments

M. E. Limes, E. L. Foley, T. W. Kornack +6

We present a method of optical magnetometry with parts-per-billion resolution that is able to detect biomagnetic signals generated from the human brain and heart in Earth's ambient…

Fluctuation signatures of rotation reversals and non-local transport events in KSTAR L-mode plasmas

Yuejiang Shi

Experiments of electron cyclotron resonance heating (ECH) power scan in KSTAR tokamak clearly demonstrate that both the cut-off density for non-local heat transport (NLT) and the t…
