All the laser beams are then switched off - the missing six orders of phase-space density are gained in complete darkness using evaporative cooling in a magnetic trap. Evaporative cooling is done by continuously removing the high-energy tail of the thermal distribution from the trap.

WebMar 1, 1997 · In our experiments we start with sodium atoms effusing from an oven at a temperature of 600 K (a velocity of 800 m s -1) and a density of about 10 14 cm -3. Over a distance of 0.5 m the atoms are first slowed with a laser beam to a speed of around 30 m s -1. This is slow enough for around 10 10 atoms to be captured in a magneto-optical trap.
