中文摘要:
      高功率输入耦合器是为自由电子激光装置的超导腔传输微波功率的部件。为了提高传输性能,需要在耦合器上镀铜膜。本文基于两种不同镀铜膜工艺实验,通过线性扫描、粗糙度、XRD和残余电阻率(RRR)对比分析在常温(25 ℃)以及200 ℃、400 ℃、600 ℃和910 ℃等四中不同温度退火后镀铜膜的性能变化,确定出适合特殊环境条件下高功率输入耦合器波纹管内壁镀铜膜工艺。将这一工艺应用于1.3 GHz高功率输入耦合器镀铜膜。结果表明,铜膜与耦合器内表面的结合力、高低温适应性和微波能量传输效率都能很好地满足实际应用的要求。

英文摘要:
      An The fundamental power input coupler is a component of the free electron laser device, which transmits microwave power to the superconducting cavity. In order to improve the transmission performance, the coupler needs to be coated with copper film. In this paper, the coupler was plated with copper film by electroless plating and electroplating, respectively. Though the linear scanning, roughness, X-ray diffraction and residual resistivity ratio, the performance changes of the copper films prepared by these two copper plating methods at room temperature (25 ℃) and after vacuum annealing temperatures (200 ℃, 400 ℃, 600 ℃ and 910 ℃) were investigated. Furthermore, the copper plating technology for the inner surface of bellows of the coupler was determined, and this process was applied to the 1.3 GHz fundamental power input coupler. The results show that the bonding force between the copper film and the inner surface of the coupler and the efficiency of microwave energy transmission can meet the requirements of practical application.
