| 520 | _ | _ | |a For decades, Lamb-shift polarimeters have been used successfully to measure the nuclearspin polarization of hydrogen and deuterium atomic beams as well as proton and deuteronbeams. In particular, they are used for polarized atomic beam sources, which in turnare used as sources for accelerators or as internal gas targets in collision experiments. Inprevious experiments it has been shown that Lamb-shift polarimeters are also suitablefor measuring the nuclear spin polarization of hydrogen and deuterium molecules andmolecular ions. Since polarized atomic beam sources are largely exhausted in terms oftheir intensity and since nuclear spin-polarized molecules are advantageous in variousapplications, the development of a polarized molecular beam source was started at theBudker Institute for Nuclear Physics in Novosibirsk. It has already been demonstratedthat with a prototype of such a source, parts of the molecular beam can be focused,which is an indirect proof of successful polarization of the beam.In order to confirm this result with a direct polarization measurement and to determinethe degree of polarization, a Lamb-shift polarimeter was build at the research centerJülich, in cooperation of the Peter-Grünberg Institute, the Institute for Nuclear Physicsand the Institute for Laser and Plasma-Physics of the Heinrich-Heine University Düsseldorf.After checking the components and optimizing the magnetic field homogeneity of theSpinfilter in Jülich, the Lamb-shift polarimeter was sent to Novosibirsk and connected tothe source. The functionality of the polarimeter has been shown through first measurementswith atomic beams.In addition, a Lamb-shift polarimeter setup in Jülich was supplemented by a secondSpinfilter and two coils to carry out experiments with Sona transitions in the 2S1/2 stateof hydrogen atoms. It turned out that such a setup is capable of performing spectroscopywith quantum energies in the order of 10 neV. |
