Buffer Gas Loading Rubidium BEC Atomic Waveguides Hydrogen-Lithium Buffer Gas Loading Theory In The CUA


Goals

  • To develop new techniques for creating and studying ultracold hydrogen and deuterium, employing buffer gas loading with a second species to accelerate cooling
  • To implement these techniques in a new-generation apparatus for studying ultracold hydrogen and deuterium.

Features

  • Buffer gas loading of hydrogen and lithium
  • Accelerated cooling of hydrogen by collisions with lithium
  • Possibility for trapping deuterium
  • Laser ablation source hydrogen, deuterium and lithium
  • Initial cooling in sepherical quadrupole trap
  • Final cooling in linear quadrupole trap (Ioffe-Pritchard trap)
  • New cryogenic apparatus to optimize buffer-gas loading
  • Method avoids need for liquid helium films

Applications

  • Ultraprecise spectroscopy of hydrogen and deuterium
  • Study of H-H, H-D and H-D interactions in ground and excited states
  • Study of quantum degenerate hydrogen and deuterium
