Abstract: Background

Accuracy and consistency of the excitation current are very important for high intensity heavy-ion accelerators. Usually, the long-term operation of magnetic field power supply, aging and zero drift of devices, ambient temperature, electromagnetic interference and other factors will lead to the decline of the current accuracy of some power supplies, thence affecting the consistency of current, which has a greater impact on the debugging efficiency and beam quality of high intensity heavy-ion accelerators.

Purpose

This study aims to improve and ensure the debugging efficiency and beam quality of high intensity heavy-ion accelerators.

Methods

An on-line calibration method for accelerator power supply was proposed by using system of chip (SOC). The factors affecting current accuracy are discussed and analyzed. The calibration principle was introduced and the method was implemented on Cyclone V SOC platform. Finally, experimental test was carried out to verify this calibration method. [Results &

Conclusions

The experimental results verify the effectiveness of the method that can effectively ensure the accuracy of the digital power supply of the accelerator, and provide technical support for the construction of the "12th Five-Year Plan" high intensity heavy-ion accelerator facility (HIAF).
