ATF2

What is it?

ATF2 is an international project to build and operate a test facility for the final focus system that is envisaged at ILC. The primary project goal is to establish the hardware and beam handling technologies pertaining to transverse focussing of the electron beams to nearly 40nm.

The emphasis of the effort will be on repeatable, stable operation of this beam manipulation to the level which can be readily applied to physics runs of ILC.

ATF2 will be built on KEK Tsukuba campus as an extension of the existing ATF. The ATF, which has a world record of the normalized emittance (the smaller, the better) of 3 x 10^-8 m, will provide the beam with ATF2.

How is it proceeding?

A two-volume set of the design proposal report have been published in 2005 and 2006. Construction of components has started in 2005, and an initial beam operation is expected in 2008.
