内容記述 |
In order to save flux consumption and lessen engineering requirements, the achievable toroidal loop voltagetends to be lowered in modern tokamaks. In such devices, careful optimization of the plasma startup scenariois often required to achieve a successful tokamak discharge. The PLATO tokamak, which is recently built atKyushu University, also faces challenges in the plasma startup. PLATO employs an air-cored central solenoidthat limits the loop voltage and creates stray magnetic fields. In addition, only simple capacitor banks withmodest maximum charging voltages are available for the generation of the poloidal magnetic and toroidalelectric fields in the initial operation. To realize the breakdown and plasma current ramp-up under thoseconstraints, the configuration of coils and capacitor bank settings has been optimized to produce sufficient loopvoltage while minimizing the stray field inside the vacuum chamber at the onset of the discharge. Throughthis optimization, a tokamak discharge with a plasma current of 30 kA and a pulse duration of 20 ms hasbeen achieved. |
