摘　　要：在230Me V超导回旋加速器调束的过程中,需要对束流的大小形状和对中情况进行测量分析,束流测量装置可以满足上述要求。本装置利用径向靶和包络靶可以测量半径150mm到850mm范围内的束流,采用了双X型圈密封结构,大大缩短了径向空间,密封性能好。直线驱动装置运动平稳可靠,靶杆带动靶头运动精度高,可为后续的束流测量装置的设计提供参考依据。In the process of beam adjustment of 230 MeV superconducting cyclotron, it is necessary to measure and analyze the intensity, shape and alignment of the beam. The beam measuring device can meet the above requirements. In this device, the radial probe and envelope probe can be used to measure the beam current in the range of R150 mm to R850 mm. The double X-ring sealing structure is adopted, which greatly shortens the radial space and has good sealing performance. The linear driving device is stable and reliable, and the probe pole drives the head of radial probe with high precision. Our work may provide reference for the design of the beam measuring device.
