| 520 | _ | _ | |a The capability of a Sona transition unit to induce transitions between the differenthyperfne states of atoms is known from [1], [2] and [5]. The specifc transitionthat is induced depends on the longitudinal and the radial magnetical felds of thetransition unit.Performed simulations of the occupation numbers of different Hydrogen hyperfinesubstates show that also the radial distance of the atomic beam from the beam axisto the edge of the coils seems to be important, because the radial magnetic fieldamplitude is rising from the center of a magnetic coil to the edge.This predicted behavior was proofed by measurements with a new type of a Sonatransition unit that was constructed and build for this thesis. One important resultwas that more particles take part in the hyperfine transitions inside the Sona unitby using radial offsets from the beam axis. This results in larger amplitudes of theoscillation between a high populated and high depolulated state while increasingthe current inside the Sona unit. The measurements show that especially at smallmagnetic fields the amplitudes of the oscillations for one hyperfine state is increasingwith an increasing radial offset from the beam axis.It was also possible to increase the amplitudes of these oscillations of the hyperfinestates from an unpolarized atom beam by using a radial offset. Therefore, it ispossible to polarize an unpolarized particle beam by using - in the laboratoryframe - static magnetic fields. This is an improvement of the known possibilitiesto create a polarized particle beam because of the comparatively easy and cheapway to produce and build these devices instead of other methods. |
