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.

“Kaon工厂束线设计研究”的主要研究工作是在世界上几个有特色的加速器设施上进行的。本财政年度的主要课题是：(1)辐射防护原理；(2)使用高强度加速器的核/粒子物理的发展趋势；(3)Kaon束线技术的前沿。我们特别邀请了加拿大TRIUMF实验室的两名束线专家来推动Kaon计划。不幸的是，Kaon去年被加拿大政府拒绝，Kaon工厂光束线上积累的技术现在正在消失。我们认为TRIUMF技术应该被我们所遵循，并应该被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财年最紧迫的计划。我们发现，在任何加速器设施中，辐射防护限值都在变得越来越严格。然而，实验人员对高强度光束的要求正在变得越来越强烈！由于实验区的辐射屏蔽较差，几个加速器设备无法将全强度束流引出到实验区。这一事实建议我们在比目前水平更苛刻的辐射防护条件下设计新的束线。
