30GHz RF脉冲展宽器(英文)

30GHz RF Pulse Stretcher

RF脉冲展宽器用来把高功率窄脉冲变换为较低功率的长脉冲,CLIC实验装置CTFⅡ中的功率提取结构已经可以提供功率达280MW,脉宽16ns的30GHz RF脉冲,为了用它来研究加速结构的最高表面场强和脉宽的关系,设计了30GHz RF脉冲展宽器,完成了系统设计,微波部件的设计及加工,系统的调试,最后安装在CTFⅡ上,并成功进行了高功率实验。

RF Pulse stretcher is an antiphrasis of RF pulse compressor. It is used to convert short high power RF pulse to long low power RF pulse. The Power Extraction and Transfer Structure (PETS) in CTFⅡ(Compact Linear Collider Test Facility Phase two) can provide 280MW 16ns pulse. It is desirable to use it to get longer pulse to study the pulse length dependence of maximum achievable surface gradient in one of the 30GHz copper accelerating structures. The 30GHz RF pulse stretcher was designed, manufactured, tuned, installed and successfully operated in CTF D .
