Multi-Level Computer Simulation of the Energy Saver Cooling Provisions

Mathematical models have been developed to describe the detailed temperature distributions within Energy Saver cryoloops as a function of static and ramp loads. The Satellite performance as a function of the Central Helium Liquefier flows, is calculated for a single equipment specification set. The performance of the system over a wide range of parameters results in clearly defined optima and detailed far-from-design predictions. The agreement of experimental test data and the simulation prediction is explored for individual magnets, magnet strings and the Satellite-mode refrigerator.
