Abstract: | A NbTi 7 T superconducting magnet with a 338 mm bore system was rebuilt and the first expe-riment was carried out in Jan. 2009. The balancing-bridge method used for the quench detection system is analyzed and an improvement of the principle of balancing-bridge conformation is given. The inductances of the coils are calculated to estimate the proportion of the bridge arms. The appropriate parameters are selected for the balancing-bridge. |
