| Abstract: | In order to improve the accuracy and efficiency of plasma real time equilibrium reconstruction, a faster parallel code named P-EFIT has taken the place of RT-EFIT. After briefly outlining the hardware and software architecture of the EAST PCS, the integration of the parallel plasma equilibrium reconstruction code P-EFIT into EAST PCS is described. Benchmark tests are carried out to verify the integrated system's correctness using history experimental data. P-EFIT was applied for plasma shape control in EAST operation campaign and the control performance is satisfied. |
