Summary

BEFORE STARTING THE COOL-DOWN TO 4.2K A PURIFICATION PROCESS MUST BE DONE BY CIRCULATING A HELIUM GAS THROUGH A PURIFIER USING A CRYOGENIC ADSORBER. FOR THE DESIGN OF THIS CRYOGENIC ADSORBER, THERE IS NEEDED TO KNOW THE AMOUNTS OF EVOLVED GAS AND COMPONENTS FROM THE SUPERCONDUCTING GENERATORS. THIS PAPER PRESENTS A NEW METHOD OF ANALYZING TRACE-LEVEL IMPURITIES AND THE TEST RESULTS OF TIME DEPENDENT GAS EVOLVING RATES WITH THE USE OF SUPERCONDUCTING GENERATOR, HESPER 1.
