The cryostat is designed to test 3 jacketed superconducting RF cavities in a horizontal configuration in a single cool-down run at 2 K. A 2-year program is currently underway to test ESS high-beta cavities. Upon completion of this program, the facility will undertake a testing program for PIP-II HB650 cavities. In the current configuration, a solution combining passive and active magnetic shielding has been validated for the ESS requirement of field attenuation to the level of <1 uT, although continuous field measurements are not provided. This paper reports the implementation of passive and active shielding, along with simulation and experimental measurements thereof.
