项目摘要

Investigators were sent to major accelerator facilities in the world in order to collect information on the multi-purpose operation of beam lines. Main subjects investigated were super-cyclic operation of beam lines, fast computer control system, beam line elements of fast extracted beam, neutrino generation by the fast beam, and accumulation rings for secondary particles. Especially the magnetic horn system and the beam monitor system of the fast beam were investigated in order to apply new technology to our neutrino beam line under construction at KEK.The design work of the multi-purpose beam lines/experimental area was performed at the latter half of the investigation. The actual target of the design work was ;(1)Beam lines and experimental area for 50GeV Proton Synchrotron of the Japan Hadron Facility [JHF] project.Beam lines/Experimental areas for high Intensity protons, polarized particles, heavy-ion beams, were designed with the actual operation modes of super-cyclic operation including the co-existence of slow and fast extractions in one machine cycle, antiproton production, accumulation, and cooling, deceleration with fast beam. The neutrino beam line was also designed in order to apply immediately to ;(2) New Neutrino beam line under construction at the KEK-PS.The beam intensity monitors employed in the neutrino beam line at KEK were designed and constructed with new technology investigated in the present work. In addition, the new neutrino beam line constructed at KEK can accept both fast. and slow beams. Such beam lines that accept both beams have never been realized. This is a very good example of the immediate feed back of our investigation to the actual construction of the realistic facility.

调查人员被派往世界各地的主要加速器设施，以收集有关束流线多用途操作的信息。主要研究内容包括束流线的超循环操作、快速计算机控制系统、快速提取束流的束流线元、快速束流产生的中微子、二次粒子的积累环等。为了将新技术应用到KEK正在建设的中微子束流线中，重点研究了磁喇叭系统和快束的束流监测系统。多用途波束线/实验区的设计工作在调查的后半段进行。设计工作的实际目标是；(1)日本强子设施[JHF]项目50GeV质子同步加速器束流线和实验区。设计了高强度质子、极化粒子、重离子束流的束流线/实验区，采用了一个机器周期内快慢萃取共存、反质子产生、积累、冷却、快束减速等超循环操作的实际操作模式。中微子束线的设计也是为了立即适用于；(2) KEK-PS正在建设新的中微子束流线。本文采用新技术对KEK中微子束流线的束流强度监测仪进行了设计和制造。此外，在KEK建造的新中微子束线可以快速接受这两种中微子。还有慢光束。这种同时接受两束光束的波束线从未被实现过。这是一个很好的例子，说明我们的调查对实际设施的实际建设有直接的反馈。
