摘要：
The power supply circuit attached to RELAX was upgraded to vary the magnitudes of the toroidal field on a single machine. The circuit enables dual operation-tokamak and reversed field pinch (RFP)-through a switch. Consequently, the upgraded circuit enables RELAX to operate within a wide range of safety factor profiles, encompassing tokamak and RFP plasmas. This upgrade enables the production of two distinct toroidal plasmas with comparable plasma currents, providing an opportunity to conduct systematic studies on the effect of magnetic shear in relatively low-density regions, where the two-fluid effect still represents a certain lack of mutual understanding.
