The work of this thesis has been dedicated to the interaction region of the new generation experiments using internal storage cell . The items addressed concern both the gas polarized target and the tracking magnet, that are strictly connected. The gas target consist of the combination of a polarized atomic source, and a storage cell coaxial with the beam. In the atomic source, a system of small sextupoles polarizes and focalizes the atoms, that are injected in the storage cell. The cell is immersed in a holding magnetic field that assures longitudinal or transverse polarization. The field of the tracking magnet, surrounding the interaction region, must be null where the cell is located, to keep the polarization in the cell.

Abstract

The work of this thesis has been dedicated to the interaction region of the new generation experiments using internal storage cell . The items addressed concern both the gas polarized target and the tracking magnet, that are strictly connected. The gas target consist of the combination of a polarized atomic source, and a storage cell coaxial with the beam. In the atomic source, a system of small sextupoles polarizes and focalizes the atoms, that are injected in the storage cell. The cell is immersed in a holding magnetic field that assures longitudinal or transverse polarization. The field of the tracking magnet, surrounding the interaction region, must be null where the cell is located, to keep the polarization in the cell.
