Summary

THE TRANSIENT STABILITY OF A NIOBIUM-TITANIUM CABLE-IN-CONDUIT CONDUCTOR COOLED WITH SUPERCRITICAL HELIUM WAS INVESTIGATED. DATA WERE GATHERED FOR ZERO AND NONZERO IMPOSED FLOW RATES. ANALYSIS WAS CARRIED OUT BY DERIVING A HEAT TRANSFER COEFFICIENT HAVING BOTH TRANSIENT AND QUASI-STEADY-STATE COMPONENTS. RESULTS INDICATE THAT THE THEORETICAL HEAT TRANSFER COEFFICIENTS ARE INADEQUATE AND EMPHASIS SHOULD BE PLACED ON THE RATE OF COOLING BETWEEN THE CONDUCTOR AND THE HELIUM RATHER THAN ON THE HELIUM HEAT CAPACITY ; AN IMPOSED FLOW RATE OF LIMITED MAGNITUDE HAS THE GREATEST EFFECT IN THE REGION OF MULTIPLE STABILITY ; AN INCREASE IN THE CONDUCTOR SURF ACE AREA BRINGS ABOUT AN INCREASE IN BOTH THE STABILITY MARGIN AND THE LIMITING CURRENT.
