For achieving the high luminosity required at the International Linear Collider (ILC), it is critical to focus the beams to nanometer size with the ILC Beam Delivery System (BDS), and to maintain the beam collision with a nanometer-scale stability.
To establish the technologies associated with this ultra-high precision beam handling, it has been proposed to the ILC community at the 1st ILC Workshop to implement an ILC-like final focus optics in an extension of the existing extraction beamline of ATF at KEK. The ATF is considered to be the best platform for this exercise, since it provides an adequate ultra-low emittance electron beam in a manner dedicated to the development of ILC.
The two major goals for this facility, called ATF2, are :
As is evident from the ATF MoU, the construction and operation of ATF2 will be executed under the leadership of the Deputy and Sub-Deputy for the ATF2 project within the framework of the ATF International Collaboration.
The scientific justification for the ATF2 project and its technical design have been described in Volume 1 of the ATF2 Proposal. In Volume 2, we have presented specifics of the construction plans and the group organization to execute the research programs at ATF2.
The ATF2 Proposal Volume 1 & 2 can be downloaded from here.
Please visit the ATF web sites for more detailed information. Since the ATF2 project has been discussed at the ILC-Asia WG4 meetings before the ATF Internatinal Collaboration was (re)organized, detailed information can be found in the minutes.
