Experimental Procedure:
The double electron recombination experiment relies on modulating the electron beam using a high-voltage platform. The synchronization between the electrostatic deflection plate power supply and the modulation pulse plays a critical role in maintaining the electron beam trajectory. This experiment builds on the modulated high-voltage platform and upgrades the electrostatic deflection plate power supply for testing.

The experiment uses a FUG high-voltage power supply for the electron gun electrodes and a high-voltage amplifier for modulation. The Aigtek differential amplifier is employed as the power supply for the electrostatic deflection plates. After setting up the experimental platform, the accelerator beam trigger timing is monitored. The FUG power supply generates the electron beam, while a self-developed control device simultaneously drives the modulation voltage and the electrostatic deflection plate power supply voltage (ATA-2161). The synchronization between these voltages and the bipolar synchronization applied to the positive and negative plates of the electrostatic deflection plates is tested.

Experimental Results:

Figure 2: Experimental Results

The test results indicate that the electrostatic deflection plate power supply, utilizing Aigtek’s high-voltage differential amplifier, produces positive and negative pulse voltages that closely track the modulation voltage. This effectively maintains the electron beam trajectory and enables high-precision double electron recombination experiments. The measured electron-ion recombination resonance waveforms align well with theoretical calculations. These findings further validate that Aigtek’s high-voltage differential amplifier achieves precise differential output. This innovation simplifies the synchronization control process, reducing the need for two power supplies to a single unit, thereby lowering costs and minimizing control complexity.
