The purpose of ATF2 project is to develop and establish a new final focus method, called"
Local Chromaticity Correction (LCC)", which will be used at International Linear Collider …

Aiming to simplify the machine detector interface of the Compact Linear Collider (CLIC), a
new detector model has been designed allowing the last quadrupole QD0 of the final focus …

The KEK accelerator test faciliry (ATF) conducts R&D; on a beam for the Linear Collider. The
damping ring provides a low emittance electron beam and the final focus test beamline …

In circular colliders, as well as in damping rings and synchrotron radiation light sources,
beam halo is one of the critical issues limiting the performance as well as potentially causing …

In future linear colliders, extremely small beam size is required at collision point for high
luminosity. For example, it is of order of nanometer in ILC (International Linear Collider) …

The future machines considered to carry out high precision physics in the TeV energy
regime are electron-positron (e+ e−) linear colliders. Future linear colliders feature …

This paper provides updates on two essential toolsets designed to facilitate the tuning and
commissioning processes of the Future Circular Collider (FCC): relaxed optics and linear …

For future linear colliders, a nanometer-scale beam size at the interaction point (IP) is one of
the most challenging technical aspects. To explore the feasibility of a final focus system with …

The investigation of beam halo transverse distributions is important for the understanding of
beam losses and the control of backgrounds in Future Linear Colliders (FLC). A novel in …

We are aiming to produce an extremely small beam having a vertical beam size of 37nm at
KEK-ATF2. The beam halo surrounding the beam core will make the background for the …
