Fast Extraction Kicker for the Accelerator Test Facility
We present the results of a study for the design of a fastextraction kicker to be installed in the Accelerator Test Facility ringat KEK. This activity is carried on in the framework of the ATF2 project,which will be built on the KEK Tsukuba campus as an extension of theexisting ATF, taking advantage of the world s smallest normalizedemittance achieved there. ATF2's primary goal is to operate as a testfacility and establish the hardware and beam handling technologiesenvisaged for the International Linear Collider. In particular, the fastextraction kicker object of the present paper is an important componentof the ILC damping rings, since its rise and fall time define the minimumdistance between bunches and ultimately the damping rings length itself.Building on the initial results presented at EPAC '06, we report on thepresent status of the kicker design and define the minimumcharacteristics for pulsers and other subsystems. In addition to theoriginal scheme with multiple stripline modules producing a totaldeflection of 5 mrad, we also investigated a scheme with a single kickermodule for a reduced deflection of 1 mrad placed inside a closed orbitbump, which takes the electron closer to the extractionseptum.
