Abstract：
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 CTFⅡ .
