文摘With the calculation and measuring experiment methods,the effect of vacuum chamber materials' magnetic permeability on field distribution in a dipole magnet is discussed.The results show that when the relative magnetic permeability of chamber materialμ_r≠1,it will affect the field uniformity.Once the high field uniformity is required, the material property and size of vacuum chamber in a dipole magnet have to be taken into account carefully.
