Magnetic shielding for a transversely polarized target in the longitudinal field of the PANDA solenoid — •Bertold Fröhlich1, Samer Ahmed1, Alaa Dbeyssi1, María Carmen Mora Espí1, Kathrin Gerz1, Dexu Lin1, Frank Maas1, Ana Peñuelas Martinez1, Cristina Morales1, Yadi Wang1, and Patricia Aguar Bartolome21Helmholtz Institut Mainz — 2Institut für Kernphysik Johannes Gutenberg-Universität Mainz

A transversely polarized target in PANDA would allow for the first time access to the imaginary part of the time like electromagnetic proton form factors, namely the phase angle in the imaginary plane between electric and magnetic form factors. Moreover it would allow for a number of other target single spin asymmetries revealing nucleon structure observables connected with the transverse spin structure of the proton.

As a first step for achieving a transverse target polarization, the target region has to be shielded against the 2 T longitudinal magnetic flux from the solenoid of the PANDA spectrometer. We present experimental results on intense magnetic flux shielding using a BSCCO-2212 high temperature superconducting hollow cylinder at liquid helium temperature.
