Abstract
A rotor for a superconducting generator with improved thermal transient response is disclosed and claimed. In particular, a cylindrical radiation shield disposed about said rotor is given the twin-functions of protecting the rotor from radiant heat from the ambiance, as well as warming the coolant during abnormal operating conditions to ensure minimal damage from thermal transients. Thermohydraulic stabilization of the coolant flow through axial passages in the shield is achieved by the use of risers located within the flow path at the discharge end of the shield.
