The Polarized Internal Gas Target of ANKE

Since 2005 the ANKE spectrometer is equipped with a polarized internal target (PIT). It consists of a polarized atomic beam source (ABS) following the Stern-Gerlach experiment to produce a polarized atomic beam, a huge target chamber including a storage cell and a Lamb-shift polarimeter to control and tune the polarization. Therefore, at ANKE double-polarized experiments, i.e. with polarized beam and target, are now possible for nuclear and hadron physics and will allow to measure spin-correlation coefficients.

The ISTC Chamber

Polarized Molecules

In a collaboration of the St. Petersburg Nuclear Physics Institute, the University of Cologne and the IKP an apparatus for the investigation and optimization of storage-cell targets was developed. This device is able to measure the polarization of hydrogen and deuterium atoms and their molecules after the recombination on a surface. During the last measurements a material was found that allows the full polarization conservation during the recombination process. Therefore, the production of highly polarized hydrogen molecules is now possible. More: Polarized Molecules …

Lamb-shift polarimeter used at the Institute for Nuclear Physics

A Lamb-Shift Polarimeter for Novosibirsk

To measure the nuclear polarization of such molecular hydrogen and deuterium beams a Lamb-shift polarimeter (LSP) has proven to be an unique tool. First of all the atoms and molecules are ionized by electron bombardment inside a strong magnetic field to preserve the nuclear spin. More: A Lamb-Shift Polarimeter for Novosibirsk …
