Single-impulse magnetic focusing of launched cold atoms.

Pritchard, M. J. and Arnold, A. S. and Smith, D. A. and Hughes, I. G. (2004) 'Single-impulse magnetic focusing of launched cold atoms.', Journal of physics B : atomic, molecular and optical physics., 37 (22). pp. 4435-4450.

Abstract

We have theoretically investigated the focusing of a launched cloud of cold atoms. Time-dependent spatially-varying magnetic fields are used to impart impulses leading to a three-dimensional focus of the launched cloud. We discuss possible coil arrangements for a new focusing regime: isotropic 3D focusing of atoms with a single-impulse magnetic lens. We investigate focusing aberrations and find that, for typical experimental parameters, the widely used assumption of a purely harmonic lens is often inaccurate. The baseball lens offers the best possibility for isotropically focusing a cloud of weak-field-seeking atoms in 3D.
