Despite a cooling problem that has been identified and will be addressed, the system has achieved 300 amp-turns of magnetic flux to date.
Its laboratory setup uses a gaseous helium-cooled 40-meter bismuth calcium copper oxide HTS cable to produce 4100 amp-turns, a magnetic flux that is comparable to the existing copper-based degaussing cables used in military ships.
At present, the Carderock group is adding amp-turns to its system and checking the magnetic performance of the system, according to Fitzpatrick.
