介绍了合肥电子储存环新凸轨注入系统中将采用的超高真空陶瓷镀钛真空室的研制状况。对穿过真空室镀膜的脉冲磁场特性进行了理论分析与计算。讨论了不同的镀膜厚度及方式对脉冲磁场均匀性的影响，用跟踪程序计算了注入过程磁场径向不均匀性对束流轨道的扰动，给出了涡流引起的磁场径向不均匀性最大允许值。
The research status of ultra-high vacuum ceramic titanium-coated vacuum chamber to be used in the new convex rail injection system of Hefei electronic storage ring is introduced. The characteristics of pulsed magnetic field passing through vacuum chamber coating were theoretically analyzed and calculated. The effects of different coating thickness and mode on the uniformity of pulsed magnetic field are discussed. The tracking program is used to calculate the perturbation of the beam trajectory due to the radial inhomogeneity of the magnetic field during the injection. The maximum allowable radial unevenness of the magnetic field caused by eddy current is given value.
