Abstract
A pressure control system for the cryogen pressure vessel of a helium cooled superconducting magnet assembly including a helium gas recondenser to return liquid helium to the helium supply including a temperature sensor proximate to the recondenser to provide a control signal for maintaining a preselected temperature of said recondenser in order to maintain a preselected pressure within said helium vessel above the pressure outside the vessel and further including an indication of the thermal conductance across the interface between the recondenser and the cryocooler which cools the recondenser.
