REMARKS ON CONTAMINATION OF LIQUID HELIUM WHEN COOLING SUPERCONDUCTING GENERATORS.

Author(s) : KOFLER H.

Summary

RELIABILITY IN SERVICE IS THE ESSENTIAL CHALLENGE FOR A SUPERCONDUCTING GENERATOR OPERATING THOUSANDS OF HOURS. THE COOLING CIRCUIT IS A KEY TO THIS RELIABILITY. ON ITS WAY FROM THE REFRIGERATOR TO THE ROTOR OF THE GENERATOR AND BACK, THE REFRIGERANT PASSES ALONG SEVERAL SOURCES WHERE CONTAMINATION MAY OCCUR. THE PAPER DESCRIBES A SIMPLE EXPERIMENTAL SET UP WHICH IS INTENDED TO DETECT THE AMOUNT OF CONTAMINATION PRESENT AT THE OUTLET OF THE GENERATOR COOLING CIRCUIT. SEVERAL STEPS OF THE START UP AND OPERATIONS OF THE GENERATOR ARE MONITORED WITH RESPECT TO CONTAMINATION.
