X射线束位置监测器是为SPring-8插入装置束线设计和安装的。这些监视器正用于光子束诊断。SPring-8标准波荡器输出的光束总功率为11 kW，功率密度为470 kW/mrad ~ 2。每台监视器都有四个CVD金刚石刀片，上面涂有金属，用于探测器头。我们已经介绍了三种类型的监视器，以匹配SPring-8中的各种插入设备。标准型或固定叶片型主要用于标准真空波荡器光束线。水平叶片驱动方式和四叶片驱动方式分别用于具有宽功率分布的摇摆器和双螺旋波荡器的光束线，以及用于具有不对称功率分布的8字形波荡器。本文详细介绍了这些监测器的设计和结构，以及用于光子束诊断的束流测试。
The X-ray beam position monitors had been designed and installed for SPring-8 insertion device beamlines. These monitors are being utilized for photon beam diagnostics. The beam from the standard undulator in SPring-8 has the total power of 11kW and the power density of 470kW/mrad2, typically. Each monitor has four CVD diamond blades coated with metal for detector heads. We have already introduced three styles of monitors to match various insertion devices in SPring-8. A standard style, or a fixed-blade style, is used mainly for a standard in-vacuum undulator beamlines. A horizontal-blade-drive style and a four-blade-drive style are used for beamlines of a wiggler and a twin helical undulator that have wide power distributions, and for figure-8 undulators that have asymmetric power distributions, respectively. This report describes the design and the structure of these monitors and the beam-tests for the photon beam diagnostics in detail.
