Abstract

A large size Bi-2223 HTS magnet coil were manufactured and tested. The HTS coil comprises 45 double pancakes which are grouped into 5 sets. Each set has 9 pancakes connected in series and the 5 sets are connected in parallel to form the coil. The coil has a diameter of 2.1 meters and total turns of 2520. The I_c of the coil is 350 A at 77 K. During and after manufacture of the HTS coil, a series of tests were conducted to examine the performance of the HTS coil. In this paper, the manufacture procedure, parameters of the coil, and test results will be presented.
