Author(s) : YUCEL S., ALEXANDER N., HONIG A.
Type of article: Article
Summary
A NOVEL HELIUM-GAS-FILLED COAXIAL INSERT SEALED WITH CERAMIC FEEDTHROUGHS, WHICH THERMALLY GROUNDS THE SUPERCONDUCTING NIOBIUM INNER CONDUCTOR OF A COAXIAL TRANSMISSION LINE AT THE 1.3 K POT OF A DILUTION REFRIGERATOR, IS DESCRIBED. TWO LINES ARE USED TO ACCESS A CW NMR SYSTEM INCORPORATED IN AN OXFORD INSTRUMENTS MODEL 200 TOP-LOADING DILUTION REFRIGERATOR, RESULTING IN A RISE OF THE BASE TEMPERATURE FROM 10 UP TO 12 MILLIK. THE THERMAL IMPEDANCE OF THE INSERT WITH AND WITHOUT HELIUM IS ANALYZED BETWEEN 1.5 AND 6 K.
