High Precision Measurements
- Penning trap - Magneto-Optical Trap (MOT)
Why traps?
laser beam
1 million Na atoms Temperature lt 1 mK

cold atoms
An example for a magneto-optical trap for sodium
at KVI (R.Morgenstern et al.). Here the cold
cloud of sodium atoms is used as a target for low
energy ion scattering experiments (Recoil
momentum spectroscopy, J.W.Turkstra et al. PRL
87, 123202 (2001) ). This technique will be used
in ? decay experiments.
