Bose-Einstein Condensation in Sodium

Ketterle graph

Figure 1
"Observations of BEC in sodium atoms achieved in the MIT group. The left-hand side shows shadow images, where the density of the condensate is seen to grow with decreasing temperature from left to right. The right-hand diagram show cuts through the density as the condensate develops." The figure is from [1].

Ketterle notes

Figure 2
"One page of the lab book during the night of September 29, 1995, when BEC was first observed at MIT. The hand writing is by Klaasjan van Druten. At 5:50 a.m., we had installed a new acousto-optical modulator to switch off the optical plug (Ar ion laser beam). Fifteen minutes later, we had the first definitive evidence for BEC in sodium." The figure is from [2].
