Abstract
The present invention discloses a magnetic probe device. The magnetic probe device includes a magnetic probe body and a signal processing circuit, and an output end of the magnetic probe body is connected with an input end of the signal processing circuit; the signal processing circuit includes a first capacitor, a second capacitor, a Faraday shield and a step-up transformer, and the Faraday shield is fixedly arranged between a primary winding and a secondary winding of the step-up transformer; a center tap is arranged at the primary winding of the step-up transformer, and the center tap is grounded; and a first end of the primary winding is in series connection with the first capacitor, and a second end of the primary winding is in series connection with the second capacitor. The magnetic probe device provided by the present invention can improve the signal-to-noise ratio of a magnetic probe and the measurement accuracy of the magnetic field in plasma.
