摘要

摘要: 直流高压加速器离子源系统需在兆伏级高压平台运行，有线通信介质如光纤在紧凑型使用工况下由于耐压局限性而存在击穿风险。为此，设计并研制了一种基于无线光通信（WOC）的离子源控制与采集系统样机，针对2.5 MV直流高压加速器中电感耦合等离子体（ICP）离子源系统中的高压电源、射频电源和质量流量计所需的模拟量控制与采集要求，采用差分输入模数转换（ADC）对控制与采集原始信号进行采样，经数字处理后通过无线光通信传输；无线光信号通过光电转换，再经数模转换（DAC）和放大电路重构原始信号。通过搭建离线测试平台，验证所设计的无线光系统能够稳定控制直流高压加速器离子源系统相关设备。实验测试结果表明，该无线光系统满足硼中子俘获治疗（BNCT）项目的技术要求，具备在2.5 MV直流高压加速器离子源系统中应用的可行性。

Abstract: Background
The ion source system for DC high-voltage accelerators operates at megavolt-level high-potential platforms, where wired communication media such as optical fibers face the risk of dielectric breakdown in compact applications due to voltage withstand constraints.
Purpose
To address this, a prototype of ion source control and acquisition system based on wireless optical communication (WOC) is designed.
Methods
For the analog control and acquisition requirements of high-voltage power supplies, RF power sources, and mass flow controllers in the 2.5 MV DC high-voltage accelerator’s inductively coupled plasma (ICP) ion source system, differential-input analog-to-digital conversion (ADC) is adopted to sample raw control and acquisition signals. After digital processing, signals are transmitted via WOC. The optical signals are converted via photoelectric conversion, then reconstructed into original analog signals through digital-to-analog conversion (DAC) and amplification circuits. In this design, a ZYNQ-based digital processing platform coordinates the acquisition, transmission, and reconstruction processes, which enables ADC/DAC data interaction and stable Ethernet optical communication, ensuring the overall integrity of the wireless optical control system.
Results
An offline test platform verified that the designed WOC system can stably control the relevant equipment in the DC high-voltage accelerator ion source system. The transmission accuracy remained within the 1.5% deviation requirement, and the link operated reliably over long durations.
Conclusions
Experimental results indicate that the WOC system meets the technical requirements of the BNCT project and is feasible for application in the 2.5 MV DC high-voltage accelerator ion source system.
