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上的主要加速器设施，以收集关于束线多用途操作的信息。主要研究内容包括束线的超循环运行、快速计算机控制系统、快引出束的束线元件、快束产生中微子以及次级粒子的积累环。为了将新技术应用于正在建设的快中子束流线，重点研究了磁喇叭系统和快束流监测系统，并在研究的后半部分进行了多用途束流线/实验区的设计工作。设计工作的实际目标是：（1）日本强子装置（JHF）50 GeV质子同步加速器的束流线和实验区：强流质子、极化粒子、重离子束的束流线/实验区设计采用了一个机器周期内慢、快引出共存、反质子产生、积累、以及冷却、快速束流减速。中微子束线的设计也是为了立即应用于：（2）新的中微子束线正在建设中的KEK-PS。在KEK的中微子束线中使用的束流强度监测器的设计和建造的新技术在本工作中的研究。此外，KEK建造的新中微子束线可以快速接受两者。慢光束这种接受两个光束的光束线从未实现过。这是一个很好的例子，我们的调查立即反馈到现实设施的实际建设。
