To create a source of metastable helium atoms for atom optics experiments we have developed a bright beam facility for metastable atoms.
We use this facility for two types of experiments;
- Atomic beam experiments: 3 x 1010 atoms / second in a 2 mm2 area, <100 m/s, < 10 mrad divergence;
- Atom trap experiments: 3 x 109 atoms in an 8 mm diameter cloud, with temperature 0.3 – 1.0 mK (corresponding to velocities ~ 1 m/s).
In addition, we have developed a more compact beam line to create a Bose-Einstein condensate of metastable helium atoms in a separate lab which is part of the ARC Centre of Excellence for Quantum-Atom Optics.
