Abstract:

To reconstruct the HL-2A plasma boundary, current filaments (CF) codewith the filament current model is written.Computed results based on the external magnetic measurements show that the CF code can accurately identify the limiter plasma,and the diverted plasma with its X point position. The time ofthe appearance and disappearance ofthe strike point at the target is in agreement with the signals measured by the static electric probes. Using an ordinary PC (Pentium 2.4GHz, 800MHz data bus), the calculation time of the plasma parameters is less than 1ms.
