论文摘要
我们介绍了为20英寸低背景的Osiris设施开发的磁性屏蔽的技术设计和特性。在设计中使用了一种无定形合金的丝带,具有极端的磁渗透性,从而提供了相对较少材料的材料质量的材料的质量相对较少的材料的构造,从而使材料的构造具有重要的材料。与筛选地球磁场的其他方法相比,成本效益。
We present the technical design and characteristics of the magnetic shield developed for 20" PMTs of the low-background OSIRIS facility. A ribbon of amorphous alloy with the extreme magnetic permeability was used in its design providing the excellent efficiency in screening the Earth's magnetic field with a relatively small amount of the material. The mass of materials is crucial for the construction of low-background facilities from the point of view of radioactive backgrounds. Using amorphous materials is cost-efficient compared to other methods for screening the Earth's magnetic field.
