ATF experiment under repair

At the end of May 1991, an electrical short caused extensive damage to one of the large helical windings of the Advanced Toroidal Facility (ATF). The ATF is currently being repaired to preserve the option of restarting the program. In addition, the ATF group hopes to double the plasma heating on the ATF and to extend operation to the long-pulse, steady-state regime for which the device was designed.
