Design of High-Gain Amplifier for Soft X-Ray Imaging Diagnostic System on J-TEXT Tokamak

Abstract:

Amplifier is a key component of the Soft X-ray imaging diagnostic system and the system is one of the most important diagnostic systems on J-TEXT tokamak. Signal generated by the photodiode is current and it’s too small. A high-gain amplifier enable us to observe the soft x-ray radiation signal in J-TEXT tokamak accurately. So an amplifier based on transimpedance circuit was proposed. Through theoretical calculations and simulations, the designed amplifier can achieve the set goals that are the V/I gain of 10⁶ and the bandwidth of 20KHz. In order to ensure the quality of the signal, interface and shell of the amplifier are designed specially. Finally designed amplifier works properly in the experiment and it can meet the needs of the experiment.
