Vacuum breakdown characteristics for long gap and large surface area electrodes under uniform electric field condition were investigated. Sample electrodes have different surface conditions which are machined by a diamond cutting tool or normal cutting tool. Another electrode is processed by the chemical polishing method. These electrode surfaces are analyzed by the XPS (X-ray Photoelectron Spectroscopy). We obtained the influence of the surface condition on the vacuum breakdown characteristics for large sized electrode and long gap distance. And the area effect on thebreakdown voltage for the copper electrode gap in vacuum was investigated.

研究了均匀电场条件下长间隙大表面积电极的真空击穿特性。样品电极具有不同的表面条件，其由金刚石切削刀具或普通切削刀具加工。另一个电极用化学抛光法加工。通过XPS（X射线光电子能谱）分析这些电极表面。得到了大尺寸电极和长间隙距离下表面条件对真空击穿特性的影响。研究了真空中铜电极间隙面积对击穿电压的影响.
