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-time extraction of the imaginary part from the latter. The measurement of this will open a new window for investigating the nucleon structure.

A transversely polarized target in PANDA implies that the longitudinal magnetic flux density applied by the PANDA-solenoid has to be shielded. A numerical simulation of the shielding with a Bi-2212 superconducting tube was performed.
