摘要

摘要: 为了研究靶前高功率束流的物理特性，欧洲散裂中子源计划研制一套靶前多丝束流剖面监测器及束晕监测器样机，样机的在线测试将在日本质子加速器研究设施的3 GeV质子束传输束线上进行。针对此束线现场安装管道狭小、监测器样机传动机构行程大的特点，提出一种适用于小通道的多点定位多丝束流剖面探头，将其与束晕探头集成在一个样机上，结构紧凑，可实现双探头的独立驱动。使用ANSYS workbench对探头及传动杆进行了变形分析，完成了样机的研制，通过丝间距光学影像测量、真空检漏、小孔通过性测试及通断检测，确保了样机的可靠性。

Abstract: In order to study the physical characteristics of high power beam in front of target, the European spallation neutron source plans to develop two beam diagnostic prototypes, including a multi-wire beam profile monitor and a beam halo monitor. Online testing of the prototypes will be conducted on the 3 GeV proton beam transmission line (3NBT) at J-PARC of Japan. In view of the small installation pipe on dump of 3NBT, and the drive mechanism of the prototype should have a large stroke, a multi-wire beam profile monitor of multipoint position suitable for small pipe is proposed, which is integrated with beam halo probe in one prototype. The prototype has compact structure and can realize independent drive of two monitors. The deformation of the monitors and their transmission rods has been analyzed by using ANSYS Workbench. The development of the prototype is completed. To ensure the reliability of the prototype, the off-line testing, such as optical image measurement of wire spacing, vacuum leak detecting, small aperture pass testing and on-off testing has been completed.
