AbstractManufacturing cost of the metal based Power Extraction and Transfer Structure (PETS), one of the core components to of Compact Linear Collider (CLIC), is one of the major concerns to build the next generation high energy physics machine, CLIC. We propose a research program to study the possibility to replace the current metal based PETS with its dielectric counterpart, which will significantly reduce the cost if it successes. A quartz based PETS testing structures will be built, instrumented, and cold tested preparatory to high power measurements in Phase II. The overall objective for the proposed Phase I program is the design, development, and fabrication of a 11.424 GHz dielectric based RF power extractor, which is a scaled version of 12 GHz extractor in order to perform the high power rf test first using SLAC 11.424 GHz high power rf source before moving toward a real beam test of the 12 GHz version. Phase I will culminate in the rf bench test of the 11.424 GHz dielectric structure and matching section. Applications and benefits: The power extractors presented here may lead to a good alternative to PETS, a key component for the CLIC machine. Besides applications for high energy physics, the high power rf source can find a variety of applications in the microwave industry, communications, and radar systems.
