摘要
In order to study the technology on cyclotron design,and to carry out researches on the crucial parts including the main magnet,beam diagnostics and engineering technology to accomplish the experimental verification of the 100MeV high intensity cyclotron and to pave the way for further increasing the current of the proton beam,a series of work has been done in succession since 2004,which highlights the research,design and fabrication of some of the critical parts.The technical requirement for each part has been reached consecutively.At present,all the work has been integrated into a set of comprehensive device,CRM Cyclotron,which is actually a test stand for high intensity cyclotron development.This report will lay emphasis on the following:the CRM Cyclotron design and fabrication of relevant equipment,magnetic field mapping and shimming,10—15mA H- ion source,experimental research on RF cavity and injection system,beam commissioning on the internal target system,etc.
为了试验研究强流回旋加速器的整机设计技术,主磁铁、束流诊断等关键部件的设计与加工工艺技术,以完成100MeV回旋的设计验证,并为今后逐步提高流强创造试验条件,自2004年以来,陆续研究、设计、加工了一些关键部件,先后实验研究达到了单项技术指标;目前,已集成为一套强流回旋加速器的综合试验装置.本文报告该试验装置的设计与设备制造情况、磁场测量与垫补结果、10—15mA负氢离子源、高频腔和注入系统实验研究、内靶束流调试等工作.
