Abstract

The next generation of polarized high energy physics experiments at accelerators employing internal targets requires a significant increase in density of the target. In an atomic beam source electron polarization is obtained from Stern-Gerlach separation by sextupole magnets and then transferred to nuclei by means of RF transitions. The Università di Ferrara and INFN group is developing a new ABS characterized by a high intensity beam, using superconducting sextupoles instead of a permanent magnet system. The field mapping of a NbTi sextupole performed in Ferrara at low temperature and full current is presented. A dedicated test bench was employed for the low temperature field map in the Ferrara laboratory.
