Cross-calibration of atomic sensors for pressure metrology
Erik Frieling, Riley A. Stewart, James L. Booth +1
Atomic sensors have shown great promise for density and pressure metrology in the high, ultra-high, and extremely-high vacuum regimes. Specifically, the density of background gas p…
Trapped particle evolution driven by residual gas collisions
Avinash Deshmukh, Riley A. Stewart, Pinrui Shen +2
We present a comprehensive mathematical model and experimental measurements for the evolution of a trapped particle ensemble driven by collisions with a room-temperature background…
Cross-calibration of atomic pressure sensors and deviation from quantum diffractive collision universality for light particles
Pinrui Shen, Erik Frieling, Katherine R. Herperger +6
The total room-temperature, velocity-averaged cross section for atom-atom and atom-molecule collisions is well approximated by a universal function depending only on the magnitude…
Measurement of Rb-Rb van der Waals coefficient via Quantum Diffractive Universality
Riley A. Stewart, Pinrui Shen, James L. Booth +1
Collisions between trapped atoms or trapped molecules with room temperature particles in the surrounding vacuum induce loss of the trapped population at a rate proportional to the…
