A model is presented for a nuclear demagnetization cooling system in which the metallic refrigerant is distributed over a region where the magnetic field varies by a large amount. A method employing "quasi-steady-state" approximations is used to solve the problem in the framework of finite difference procedures. The predictions from the model are used to establish a number of design parameters in cryostats for studies of superfluid 3He and ultra-low-temperature metals physics.
