| 概要 | Operation of the S-1 device in a high-current-density (jne2×10-14 A m) regime has created high-electron-temperature spheromaks (50 eVTe130 eV). The mechanisms and causes of the periodic relaxation events often observed in these hotter plasmas were made clear. A relationship between the MHD relaxation cycle and confinement was revealed for the first time. Resistive loss at the outer edge causes a departure from the initial force-free minimum-energy Taylor state to an MHD profile unstable to low-n ideal MHD modes; a relaxation event then returns the configuration to a Taylor state. © 1988 The American Physical Society. |
