A vapor-cooled lead system that used six pairs of leads in twelve separate dewars was built for the International Fusion Superconducting Magnet Test Facility (IFSMTF). Each of these leads was cooled by helium vapor from a reservoir separate from the pool-boiling or force-flow coil. Satisfactory acceptance tests were performed on the early production runs of the leads. Inconsistent and anomalously high heat losses were observed on the two pairs of lead assemblies used in the partial-array test. Subsequent tests on the leads and their associated dewars confirmed satisfactory performance of the lead and dewar and offered an explanation for the excessive losses during the partial-array test.
