In a reversed field pinch (RFP), a thick metal shell has to be closely fitted to a plasma for stability requirement. In optimizing the design of an equilibrium control system, the shell causes several problems, such as the production of the error magnetic field (Bg-err) at insulating gaps of the shell and shielding of the fast varying vertical field which actively controls the plasma position. To solve these problems, the equilibrium control system in the nuclear fusion experimental machine TPE-1RM15 (major radius 0.7m, minor radius 0.135m) is designed to have a thick copper shell with 25mm thickness, fast varying vertical field of 110mT (Bcv), quasi-stationary vertical field of 20mT (Bdcv), pulsed vertical field produced inside the shell (Bpv) and local compensating field at shell gaps (Bsdc). The shell provides main equlibrium vertical field, Bcv compensates Bg-err, Bdcv controls the plasma position, Bpv cancels the Bdcv at initial plasma breakdown and Bsdc provides additional compensating field for Bg-err. Experimental results with the system show that the compensation of Bg-err is essential for setting up and maintenace of RFP configuration and that plasma resistance decreases from 470 to 280μΩ with the equilibrium position control in the order of mm.
