| Research Abstract |
To study the characteristics of breakdowns in different materials under a high RF field, a high-gradient experiment was proposed with using narrow waveguides which are reduced the height and the width in order to obtain a field of around 140 MV/m at 50 MW power. The breakdown rate, the sustainable electric field and the surface observation after high-gradient experiment were conducted on the two waveguide of copper (OFC) and stainless-steel (AISI-316L). The breakdown rate of the copper waveguide was found to be larger than that of the stainless-steel waveguide and they have different property corresponding to the electric fields and the pulse widths.
