Summary EPICS has been adopted for the control system development of ITER Fast Controller prototype based on PXI/PCIe technology. The TF Coil Power Supply System use case has been chosen to be implemented for the ITER Fast Controller prototype. The Fast Controller prototype will be used as the test tools for ITER mini-CODAC and PSH. 4/15/201516
