摘　　要：目的为避免医科达加速器离子泵高温损坏,及时发现工作异常,设计一种离子泵监护装置。方法选取我院小儿康根据枪靶端离子泵的工作特性和结构特点,设计一种有效的监护方法,并将各监护部件集成于监控箱内,安装在加速器机架的合适位置。结果经过应用检验,该装置实现了离子泵工作温度的实时显示、超温报警及断电保护功能,达到预设目标。结论离子泵监护装置安装简单可靠,能有效地保护离子泵,弥补了加速器设计的缺陷,避免了经济损失。Objective In order to avoid the high temperature damage of the Elekta accelerator ion pump and detect the abnormal work in time, a monitoring device of ion pump was designed. Methods According to the working characteristics and structural characteristics of the ion pump at the gun target, an effective monitoring method was designed. The monitoring components were integrated into the monitoring box and installed in the proper position of the accelerator frame. Results After application test, the device could realize real-time display of working temperature of ion pumps, over temperature alarm, and power failure protection function, suggesting the achievement of the preset target. Conclusion The ion pump monitoring device is simple and reliable, which can effectively protect the ion pump, make up for the defects of accelerator design, and avoid economic loss.
