| Abstract: | The principle of magnetic measurements on the concentric coils of HL-2A tokamak, and the design of concentric circles system are introduced, including identification of the area difference for the coils and integral circuit design. Through an effective compensation for stray magnetic field, concentric circles diamagnetic measurement system can get a higher signal-to-noise ratio, and therefore reliable plasma diamagnetic signal in complex discharge conditions can be obtained. |
