Accelerator Test Facility 2

atf2 beamline

 

The Accelerator Test Facility 2 (ATF2) is an extension of the ATF damping ring facility at KEK, in Tsukuba, Japan. It is a scaled prototype of final focus system required for either the International Linear Collider or Compact linear collider. The aim of the ATF2 collaboration is to produce an electron beam focus of 35 nm, which is stabilised to a few nm. This will prove that the beam measurement and manipulation techniques planned for future linear colliders will be applicable to the full scale machine. 

The John Adams Institute at Royal Holloway has been significantly involved in two projects at ATF2, Beam Position Monitors (BPMs) and a micron scale laser-wire (LW). The BPM system has been running in a production since October 2009 and the laser-wire is currently being commissioned. BDSIM the Geant4 based simulation tools developed within the JAI are also being used to model the backgrounds at the ATF2 and specifically for the laser-wire Compton signal.

More generally the ATF2 is a fantastic training accelerator, with excellent opportunities for graduate students to develop skills in accelerator science but also operation.
