项目摘要

The R/D works towards the super-cyclic operation of accelerator-beamline system were investigated in CERN,FNAL,BNL and many other laboratories in the world. The most advanced thchnologies were found in CERN.FNAL is now successufully sharing its accelerator complex between fixed target antiproton production/accumulation and proton-antiproton collider experiments. BNL operates its historic AGS accelerator as a heavy-ion machine as well as a high intensity proton machine. Unfortunately many long-lived laboratories which accumulated a lot of experiences of the multi-funcitiional accelerator operations were shut down and/or being shut down! These laboratories were urgently investigated before the technologies and experiences were scattered and lost. The investigation of laboratories in former Soviet Union countries were also urgent since those laboratories are now forced to be terminated.The investigated results were open to the public at many workshops and symposiums on the beam monitors, experimental methods, and accelerator technology. It should be noted that our investigation was a sort of propaganda of the possible multi functional operation of the KEK-PS as an intense neutrino source. The new neutrino facility of the KEK-PS and the completion of the SUPER KAMIOKA neutrino detector fascinated physicists and forced them to organizing a new collaboration of the long baseline neutrino oscillation experiment using the KEK-PS and the SUPER KAMIOKA.On the other hand, many laboratories are interested in the high energy light ion beam of the KEK-PS and are proposing collaboration on the nuclear beam project. Then we will start the design study of the super-cyclic operation system of the KEK-PS beam chnnel, which will make the investigation results more definite. This design study is very important for our future JHF 50 GeV-PS as well as our present KEK-PS.

在欧洲核子研究中心（CERN）、芬兰国家实验室（FNAL）、英国国家实验室（BNL）等多个国际实验室开展了加速器-束线系统超循环运行的研究与开发工作。最先进的技术是在欧洲核子研究中心发现的。FNAL现在成功地在固定目标反质子产生/积累和质子-反质子对撞机实验之间共享其加速器复合体。BNL将其历史悠久的AGS加速器作为重离子机器和高强度质子机器运行。不幸的是，许多积累了大量多功能加速器操作经验的长寿实验室被关闭和/或被关闭！在技术和经验散失之前，对这些实验室进行了紧急调查。对前苏联国家的实验室进行调查也很紧迫，因为这些实验室现在已被迫关闭。研究结果在许多关于束流监测器、实验方法和加速器技术的研讨会上向公众开放。应该指出的是，我们的研究是一种宣传KEK-PS作为强中微子源的可能的多功能操作。KEK-PS的新中微子设备和SUPER KAMIOKA中微子探测器的完成吸引了物理学家，并迫使他们组织使用KEK-PS和SUPER KAMIOKA的长基线中微子振荡实验的新合作。另一方面，许多实验室对KEK-PS的高能光离子束很感兴趣，并提议在核束项目上进行合作。然后，我们将开始KEK-PS波束通道超循环操作系统的设计研究，这将使研究结果更加明确。这一设计研究对未来的JHF 50 GeV-PS以及目前的KEK-PS具有重要意义。
