Abstract
A superconducting magnet coil system with high resistance to quench events includes a first coil portion (1) with a first superconducting material and a second coil portion (2) with a second superconducting material. The first superconducting material has a higher critical temperature than the second superconducting material. The first and the second coil portions are bridged by a common quench protection element (6) and together with the quench protection element form a first loop. The magnet coil system also includes a third coil portion (3) which is part of a second electrical loop with a second quench protection element (8, 8′, 8″)as well as a heating element (9) which is supplied with a heating voltage in response to a quench of the third coil portion. Among the series connected coil portions (1, 2) only the second coil portion is in thermal contact with the first heating element (9).
