Reliability History and Improvements to the ANL 50 MEV H- Accelerator

L. I. Donley, V. F. Stipp, F. R. Brumwell, G. E. McMichael

摘要:

H加速器由750 keV的Cockcroft Walton预加速器和50 MeV的Alvarez型直线加速器组成.加速器自1961年以来一直在运行。自1981年以来,它一直被用作强脉冲中子源(IPNS)的注入器,这是一个用于中子散射的国家用户设施。直线加速器每脉冲提供约3.5x1012个H-离子,每秒30次(30 Hz),用于向450 MeV快速循环同步加速器(RCS)进行多圈注入。IPNS目前每年运行约4 000小时,按计划运行对于满足用户群体的需求至关重要。多年来,IPNS注入器/RCS的平均可靠性达到了95%,这在很大程度上得益于预加速器/直线加速器的平均可靠性接近99%。为了保持和提高系统的可靠性,记录需要显示每个子系统对总停机时间的贡献。源和直线加速器子系统的可靠性的历史,并已作出改进,以提高可靠性,将被描述。还将讨论在至少另外十年的运行中保持或提高这种可靠性的计划。

英文摘要:

The H- Accelerator consists of a 750 keV Cockcroft Walton preaccelerator and an Alvarez type 50 MeV linac. The accelerator has been in operation since 1961. Since 1981, it has been used as the injector for the Intense Pulsed Neutron Source (IPNS), a national user facility for neutron scattering. The linac delivers about 3.5x1012 H- ions per pulse, 30 times per second (30 Hz), for multi-turn injection to a 450 MeV Rapid Cycling Synchrotron (RCS). IPNS presently operates about 4,000 hours per year, and operating when scheduled is critical to meeting the needs of the user community. For many years the IPNS injector/RCS has achieved an average reliability of 95%, helped in large part by the preaccelerator/linac which has averaged nearly 99%. To maintain and improve system reliability, records need to show what each subsystem contributes to the total down time. The history of source and linac subsystem reliability, and improvements that have been made to improve reliability, will be described. Plans to maintain or enhance this reliability for at least another ten years of operation, will also be discussed.
