Description
The basic design of a reliable vacuum system for the HL-2A tokamak is presented. It consists of the main pumping system, pumping divertor and glow discharge cleaning (GDC) system. The main pumping system provides the pumping capability for the high vacuum of chamber, outgassing by baking and GDC. The pumping divertor initially realizes the pumping and control of edge particles in tokamak discharge. The GDC system ensures the good wall condition of the device. The preliminary operation and the data obtained with these systems are also presented. The base pressure is 4.6 x 10-6 Pa, in the preliminary physical experiment operation of the HL-2A tokamak, and the total leak and outgassing rates of vacuum chamber is below 1.8 x 10-5 Pa·m3·s-1 in 12 hours.
