摘要
利用3维电磁场计算程序MAFIA对CSR注入引出静电偏转板的物理结构进行了理论设计。该偏转板高压电极材料采用表面经过阳极氧化处理的锻铝板材,倒角半径为20mm,电极半宽度60mm,其几何形状能够同时满足电场均匀性、耐压性及机械强度的要求,切割板电极采用半钨丝半钽板的结构,入口厚度不大于0.1mm。在设计基础上制造了偏转板模型,并对之进行了真空模拟试验,结果证明该高压静电偏转板的设计方案是合理的,基本满足物理实验要求。
The injection and extraction deflectors of CSR are made of wrought aluminium with surface anodic oxidation. From the results of MAFIA calculation, the fillet radius and the width of the high voltage electrode are set to 20mm and 60mm respectively, in order to have enough homogeneous electric field region and to improve its withstand voltage. Half of the cutting electrode is a set of tungsten filaments which has a diameter of 0.1mm, and the other half is beaten tantalum. A deflector model was built and tested under the simulated running condition. The experimental result is in accord with theoretical analysis.
