Schematic of the superconducting solenoid and its positioning within the SRF gun cryomodule.

Caption

The superconducting solenoid is installed approximately 0.7 m downstream from the cavity end inside the SRF gun cryomodule. This configuration balances magnetic shielding of the cavity with the need to minimize beam emittance. Spherical aberration and multipole field effects from solenoid misalignment limit the achievable emittance reduction, especially at high bunch charges.
