Stanford group weighs in

[Historical report created from GSU BEC Homepage:]

"The following news is just in from Stanford University.

Brian Anderson, a graduate student in the research group of Mark Kasevich, observed BEC on June 28, 1997 at Stanford University.

The condensation parameters were as follows:

  • Number of atoms at transition: ~ 10,000
  • Transition temperature: ~ 300 nK
  • Species: 87Rb, |F MF> = |2 2>
  • Trap type: TOP (10 kHz)
  • Trap axial frequency: ~ 1 kHz
  • Loading: Vapor cell
  • Loading time: 150 sec
  • Evaporation time: 24 sec

Update [May 1998]: At the 1998 DAMOP meeting, the Kasevich group reported the reconstruction of the apparatus and the generation of BEC at Yale University, attaining 103 - 104 condensate atoms."
