Abstract

A significant advance in magnetic field management in a fully assembled superconducting radiofrequency cryomodule has been achieved and is reported here. Demagnetization of the entire cryomodule after assembly is a crucial step toward the goal of average magnetic flux density less than 0.5 mT at the location of the superconducting radio frequency cavities. An explanation of the physics of demagnetization and experimental results are presented.
