Simulating rotationally inelastic collisions using a Direct Simulation Monte Carlo method
O. Schullian, J. Loreau, N. Vaeck +4
A new approach to simulating rotational cooling using a direct simulation Monte Carlo (DSMC) method is described and applied to the rotational cooling of ammonia seeded into a heli…
A chopper system for shortening the duration of pulsed supersonic beams seeded with NO or Br2 down to 13 microseconds
Jessica Lam, Chris Rennick, Tim Softley
A chopper wheel construct is used to shorten the duration of a molecular beam to 13 microseconds. Molecular beams seeded with NO or with Br2 and an initial pulse width of greater o…
Resonant charge transfer of hydrogen Rydberg atoms incident at a Cu(100) projected band-gap surface
J. A. Gibbard, M. Dethlefsen, M. Kohlhoff +4
The charge transfer (ionization) of hydrogen Rydberg atoms (principal quantum number ) incident at a Cu(100) surface is investigated. Unlike fully metallic surfaces, where…
Coulomb crystal mass spectrometry in a digital ion trap
Nabanita Deb, Laura L. Pollum, Alexander D. Smith +4
We present a mass spectrometric technique for identifying the masses and relative abundances of Coulomb-crystallized ions held in a linear Paul trap. A digital radiofrequency wavef…
Collisional trap losses of cold, magnetically-trapped Br atoms
J. Lam, C. J. Rennick, T. P. Softley
Near-threshold photodissociation of Br from a supersonic beam produces slow bromine atoms that are trapped in the magnetic field minimum formed between two opposing permanent m…
On the formation and decay of a molecular ultracold plasma
N. Saquet, J. P. Morrison, M. Schulz-Weiling +4
Double-resonant photoexcitation of nitric oxide in a molecular beam creates a dense ensemble of Rydberg states, which evolves to form a plasma of free electrons trapped in…
Charge, density and electron temperature in a molecular ultracold plasma
C. J. Rennick, J. P. Morrison, J. Ortega-Arroyo +3
A Rydberg gas of NO entrained in a supersonic molecular beam releases electrons as it evolves to form an ultracold plasma. The size of this signal, compared with that extracted by…
The very slow expansion of an ultracold plasma formed in a seeded supersonic molecular beam of NO
J. P. Morrison, C. J. Rennick, E. R. Grant
The double-resonant laser excitation of nitric oxide, cooled to 1 K in a seeded supersonic molecular beam, yields a gas of molecules cm in a single selected…
Evolution from a molecular Rydberg gas to an ultracold plasma in a seeded supersonic expansion of NO
J. P. Morrison, C. J. Rennick, J. S. Keller +1
We report the spontaneous formation of a plasma from a gas of cold Rydberg molecules. Double-resonant laser excitation promotes nitric oxide, cooled to 1 K in a seeded supersonic m…
