PyLCP: A python package for computing laser cooling physics
S. Eckel, D. S. Barker, E. B. Norrgard +1
We present a python object-oriented computer program for simulating various aspects of laser cooling physics. Our software is designed to be both easy to use and adaptable, allowin…
Quantum Blackbody Thermometry
Eric B. Norrgard, Stephen P. Eckel, Christopher L. Holloway +1
Blackbody radiation (BBR) sources are calculable radiation sources that are frequently used in radiometry, temperature dissemination, and remote sensing. Despite their ubiquity, bl…
Outgassing rate comparison of seven geometrically similar vacuum chambers of different materials and heat treatments
James A. Fedchak, Julia K. Scherschligt, Sefer Avdiaj +5
We have measured the water and hydrogen outgassing rates of seven vacuum chambers of identical geometry but constructed of different materials and heat treatments. Chambers of five…
Phonon redshift and Hubble friction in an expanding BEC
Stephen Eckel, Ted Jacobson
We revisit the theoretical analysis of an expanding ring-shaped Bose-Einstein condensate. Starting from the action and integrating over dimensions orthogonal to the phonon's direct…
A Bitter-type electromagnet for complex atomic trapping and manipulation
J. L. Siegel, D. S. Barker, J. Fedchak +2
We create a pair of symmetric Bitter-type electromagnet assemblies capable of producing multiple field configurations including uniform magnetic fields, spherical quadruple traps,…
Confinement of an alkaline-earth element in a grating magneto-optical trap
A. Sitaram, P. K. Elgee, G. K. Campbell +3
We demonstrate a compact magneto-optical trap (MOT) of alkaline-earth atoms using a nanofabricated diffraction grating chip. A single input laser beam, resonant with the broad …
