Feasibility Study of a Transversely Polarized Target in PANDA — •Bertalan Feher — Helmholtz-Institut Mainz

PANDA (Antiproton Annihilation at Darmstadt) is a key project at the Facility for Antiproton and Ion Research (FAIR), i. e. an accelerator facility currently under construction at GSI Darmstadt. PANDA is a state of the art detector for antiproton-proton fixed target experiments. A transversely polarized target in PANDA allows the determination of the electromagnetic time-like form factors with unprecedented accuracy and the first extraction of the imaginary part from the latter. The measurement of this will open a new window for investigating the nucleon structure. Since the PANDA spectrometer is based on a longitudinal solenoid field, the target region needs to be shielded in order to have a transverse polarization. A high-temperature type-2 superconducting shield will be used for this purpose. Simulations using a finite element method were performed to calculate the resulting field map.
