Design and Implementation of a High-Voltage Fast Switching Positron Beam Cluster Signal System

In order to improve the focusing efficiency of the slow positron beam device, it is necessary to provide a wide Voltage amplitude and high slew rate focusing modulation waveform for the focusing device in the device. In this article, a high-voltage fast conversion operational amplifier is used as the core amplification device to design an amplification system to amplify the beam modulation waveform generated by the signal generator. The design principle and implementation method of the entire system are introduced, and the PCB diagram of the amplification circuit is provided. The performance of the amplification circuit built based on the high-voltage fast conversion operational amplifier is tested. The experimental results show that the high-voltage fast conversion operational amplifier can be used as an amplification stage for the beamforming modulation waveform generated by the signal generator. The amplified output of the actual waveform is provided to the collimator for beam compression, which has significant effects.
