Abstract
Abstract THE PARTLY STABILIZED SUPERCONDUCTIVE MAGNET IS COOLED BY SEPARATING THE HELIUM STREAM INTO TWO PART-FLOWS. ONE PART FLOW IS THROTTLED, HEATED, EXPANDED WHILE DOING WORK, AND THEN DIRECTED BACK INTO THE CIRCUIT DOWNSTREAM OF THE CONSUMER. THE OTHER PART-FLOW IS THROTTLED TO A PRESSURE ABOVE CRITICAL, COOLED, DIRECTED THROUGH A HOLLOW CONDUCTOR FORMING THE MAGNET WHILE THROTTING THE FLOW AND THEN FURTHER THROTTLED IN A VALVE TO FORM A GAS AND LIQUID MIXTURE, HEATED AND THEN RETURNED TO THE COMPRESSOR.
