초록
This study was progressed to value of Bi2212 tubes uniformity depend on cooling conditions. The tube from 150 mm in length, 30 mm in O.D., 20 mm in I.D., 5 mm in thickness was combined with electrodes by 3 sections. The tube from 60, 70 mm in length, 30, 50 mm in O.D., 20.4, 40.4 mm in I.D., 4.8 mm in thickness was in controled of cooling rate by a heat exchanger. Bi2212 tubes were fabricated by Centrifugal Forming Process (CFP) and they were annealed at
