摘　　要：计算机广泛应用于加速器系统的每个子设备当中,控制系统的运行和患者的治疗,成为加速器系统的一个重要组成部分,然而,任何一台计算机出现故障,加速器系统均将不能正常工作。本文研究使用GHOST技术备份加速器计算机软件系统和硬盘来保障加速器的安全运行。实践证明,使用GHOST技术降低了加速器系统的故障维护时间和维修成本,为提高加速器的工作效率发挥了重要作用。As an important part of the accelerator system, accelerator computers are widely used in each sub-equipment of the accelerator system for control of system operation and patients＇ treatment. However, failure of any one accelerator computer would result in malfunctioned accelerator system. In this paper, the use of GHOST technology for backup of the software system and hard disk of an accelerator computer was studied to ensure the safe operation of the accelerator. This practice proved that the use of GHOST technology reduced the maintenance time and costs of the accelerator system, and played an important role in improving work efficiency of the accelerator.
