A Hybrid Analog-digital Long Pulse Integrator for EAST Tokamak

摘要：

A prototype hybrid analog-digital integrator has been developed to be compatible with the long pulse plasma discharges on the Experimental Advanced Superconductor Tokamak (EAST), in which an analog integrator is used to integrate the input signal, and the digital processor is in charge of the integration drift. The integration drift is similarly linear and stable in controlled temperature, so its slope can be calculated and used to deduct the linear drift from the integration drift, which can reduce the drift. While the leakage of integration capacitor is not taken into account for it is so small during 1000s integration. The test results show that the processed integration drift is less than 0.4ms during 1000 s integration, which will meet the accuracy of magnetic diagnostics (MDs) in EAST Tokamak experimental campaigns.
