Nuclear-Spin Dependent Parity Violation in Optically Trapped Polyatomic Molecules

Eric B. Norrgard, Daniel S. Barker, Stephen P. Eckel +3

We investigate using optically trapped linear polyatomic molecules as probes of nuclear spin-dependent parity violation. The presence of closely spaced, opposite-parity -doub…

Challenges to miniaturizing cold atom technology for deployable vacuum metrology

Stephen Eckel, Daniel S. Barker, James A. Fedchak +3

Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of…

Quantum-based vacuum metrology at NIST

Julia Scherschligt, James A. Fedchak, Zeeshan Ahmed +10

The measurement science in realizing and disseminating the unit for pressure in the International System of Units (SI), the pascal (Pa), has been the subject of much interest at th…

Light-induced atomic desorption of lithium

D. S. Barker, E. B. Norrgard, J. Scherschligt +2

We demonstrate loading of a Li magneto-optical trap using light-induced atomic desorption. The magneto-optical trap confines up to approximately ato…

Development of a new UHV/XHV pressure standard (cold atom vacuum standard)

Julia Scherschligt, James A Fedchak, Daniel S Barker +4

The National Institute of Standards and Technology has recently begun a program to develop a primary pressure standard that is based on ultra-cold atoms, covering a pressure range…

A 3D-printed alkali metal dispenser

Eric B. Norrgard, Daniel S. Barker, James A. Fedchak +3

We demonstrate and characterize a source of Li atoms made from direct metal laser sintered titanium. The source's outgassing rate is measured to be \,$\rm{Pa}…
