A JFT-2M Tokamak auxiliary subsystem consists of a vacuum pumping system, a gas injection system, a leak detection system, a water cooling system, a glow discharge system, a boronization system, and a baking system. Control system of each part except for the baking system was replaced to new one, which utilizes a personal computer (PC), from FY 2000 to FY2002. The controllability of the system and the number of data, which can be recorded, was remarkably improved compared to the old system. This system has enough controllability for various operation condition of JFT-2M, and allows early finding and recovering of troubles. The general view of Tokamak auxiliary subsystem and detailed description of the function of the new control system are given in this report. It should be noted that this report describes detail of the operational procedure especially for He glow discharge system and the boron coating system, and thus, it can be used as an operation instruction.
