Time-like electromagnetic form factors of the proton can be experimentally accessible through the annihilation process of antiproton-proton into lepton pair. A transversely polarized proton target at the future PANDA experiment allows us to access the relative phase between the electric and the magnetic form factors of the proton. The first step to achieve the transverse target polarization is to study the feasibility of shielding the target region from the external 2 T longitudinal magnetic field generated by the PANDA solenoid. BSCCO-2212, a new high-temperature superconductor material, has been identified as a possible candidate to be used for shielding this external magnetic field. Tests with BSCCO-2212 at 4 K have taken place at the Helmholtz-Institut Mainz, and the first preliminary results will be reported here.
