Magnetic Semiconfinement of Neutral Atoms

TL;DR

This paper investigates a magnetic semiconfinement technique for producing highly collimated beams of neutral atoms with spins, considering realistic factors like trap size, magnetic field manipulation, and gravity effects.

Contribution

It introduces a comprehensive analysis of magnetic semiconfinement for neutral atoms, accounting for practical trap and environmental conditions.

Findings

Effective beam collimation achieved under various magnetic configurations.

Gravity influences atomic trajectories and must be considered in trap design.

Manipulation of magnetic fields allows control over atomic beam direction.

Abstract

A mechanism for creating well-collimated beams of neutral particles or atoms with spins is studied. The consideration is accomplished for a general realistic case, taking into account: (i) the finiteness of a cylindrical trap where the atoms to be shot out, are stored; (ii) the possibility of manipulating the trap magnetic fields in order to form different anisotropic field configurations; (iii) the presence of gravity curving atomic trajectories.
