The main research works on the "design study of the beam lines for the Kaon factory" were carried out at several characteristic accelerator facilities in the world. The main subjects of this fiscal year were investigating ;(1) principles of the radiation protection,(2) trends of nuclear/particle physics using high intensity accelerators,(3) frontier of kaon beam line technology.Especially we invited two beam line experts from Canadian TRIUMF laboratory which promoted the KAON project. Unfortunately KAON was rejected by Canadian government last year and the accumulated technologies on the beam lines of the kaon factory are dissipating now. We thought that the technology of TRIUMF should be followed by us and should be applied to our future high intensity project such as Japanese Hadron Facility. Thus it was the most urgent program in the fiscal year 1994.We found that the the radiation protection limits are becoming strict in any accelerator facility. However the requests from experimenters on the high intensity beams are becoming strong! Several accelerator facility can not extract full intensity beam to the experimental area because of the poor radiation shielding there. This fact suggests us to design new beam lines under more severe condition of the radiation protection compared to the present level.

“K介子工厂束流线设计研究”的主要研究工作是在世界上几个有特色的加速器装置上进行的。本财年的主要研究课题为：（1）辐射防护原理，（2）使用强流加速器的核/粒子物理发展趋势，（3）K介子束线技术前沿，特别邀请了推动KAON项目的加拿大TRIUMF实验室的两位束线专家。不幸的是，去年KAON被加拿大政府拒绝，现在KAON工厂在光束线上积累的技术正在消失。我们认为，TRIUMF的技术应该被我们所效仿，并应用于我们未来的高强度项目，如日本强子装置。因此，这是1994财政年度最紧迫的计划。我们发现，辐射防护限值在任何加速器设施都变得越来越严格。然而，实验工作者对高强度光束的要求越来越高！由于实验区的辐射屏蔽条件较差，一些加速器装置不能将全部强度的束流引出到实验区。这一事实表明，我们设计新的光束线在更严格的条件下的辐射防护相比，目前的水平。
