| Abstract: | A dedicated equipment to suppress the secondary electron emission was developed. Ion surface treatment of the oxygen-free copper plates and multistage depressed collectors （MDCs） were studied using it. The results show that the secondary electron emission ratio was reduced significantly after the treatment. The efficiency of the MDC and total TWT were effectively improved. |
