随着粒子加速器技术的发展,超导高频腔的性能稳定性成为了提升加速器效率和束流品质的关键因素。旨在探讨超导高频腔动态功率补偿的设计和实现方法,以提高超导加速器的运行稳定性和可靠性。通过分析超导腔失效对加速器性能的影响,提出了一种动态功率补偿策略通过实时监测超导腔的腔压,并利用Python拟合的腔压-腔耗关系曲线计算腔耗,动态调整超导腔底部加热器电源功率以补偿腔体损耗,从而提高超导腔老炼的成功率和效率,以减少失效对束流品质的影响,同时降低了腔体损坏风险节省了调试成本。研究结果表明,该动态功率补偿系统能够显著提高超导高频腔的稳定性和加速器的运行效率。
With the development of particle accelerator technology,the performance stability of superconducting high frequency cavity has become a key factor to improve accelerator efficiency and beam quality.In this paper,the design and implementation of dynamic power compensation for high frequency superconducting cavity are discussed to improve the operating stability and reliability of superconducting accelerator.By analyzing the influence of the failure of superconducting cavity on the performance of the accelerator,a dynamic power compensation strategy was proposed.The cavity pressure of the superconducting cavity was monitored in real time,and the cavity loss was calculated using the cavity pressure-cavity loss curve fitted by Python.The power of the heater at the bottom of the superconducting cavity was dynamically adjusted to compensate for the cavity loss,thus improving the success rate and efficiency of the aging of the superconducting cavity.It reduces the influence of failure on beam quality,reduces the risk of cavity damage and saves the debugging cost.The results show that the dynamic power compensation system can significantly improve the stability of the superconducting high frequency cavity and the operating efficiency of the accelerator.
