Development of the new integrator system controller on the EAST Tokamak

In order to meet with the requirements of the experiments on EAST Tokamak, and improve the maintainability and testability of the integrator system, a new integrator system controller is developed, The controller uses an ARM micro-controller and the lightweight IP protocol stack to realize the network control of the integrator system. The provided parameter setting instructions are able to remote set and fetch the amplifiers' gain parameters, and the provided control instructions provide functions including: initialization, standard signal integration, pulse signal integration, integration hold, calibration and probe test, Compared with the original design, the new controller simplifies the design of hardware and software, and improves the system performance, usability, maintainability and testability, Through laboratory and EAST field test, the integrator system controller is stable and available to meet with the requirements of EAST experiments.
