Description
The P2 experiment aims for a high precision measurement of the parity violating asymmetry in the elastic scattering of polarized electrons off unpolarized nuclei. The expected data will be interpreted as a determination of the weak mixing angle, one of the fundamental parameters of the Standard Model, with a precision competitive with measurements at LEP or LHC. The experiment includes a large superconducting solenoid magnet with a free aperture of 2.4 meters and magnetic field of 0.8 Tesla for a total weight of 20 tons.
The superconducting magnetic system including the cryostat, cryogenic service turret, power supplies and quench protection was built by SIGMAPHI and delivered to Johannes Gutenberg University of Mainz in November 2024. The paper presents the design, manufacturing and testing of the superconducting magnet.
