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 field less than 5x10-7 Tesla. An explanation of the basic physics of demagnetization as well as experimental results are presented.
