Estimating emittance growth is important for evaluation of performance of linear accelerators, especially where stable and low emittance beam is required, such as linear colliders. Usually, estimation of emittance growth is performed using tracking s

In linear accelerators, the transverse beam orbit is induced by tilts of accelerating cavities (deviation of accelerating field direction from designed beam direction) and transverse offset of quadrupole magnets. Estimating induced orbit and emittanc

We derive completely integrated formulas for emittance growth times due to intrabeam scattering for charged particle beams in the high energy limit, including the effect of lattice parameters that vary around the accelerator ring. Using accelerator l

We present the measurement results of electron beam emittance in the Accelerator Test Facility damping ring operated in multibunch modes. The measurements were carried out with an upgraded laser wire beam profile monitor. The monitor has now a vertic

For damping rings of future linear colliders, extremely low vertical emittance will be required. In an electron circular accelerator, the dominant sources of the vertical emittance are the vertical dispersion in arc sections and the x-y orbit couplin

We describe in this paper a measurement of vertical emittance in the Accelerator Test Facility (ATF) damping ring at KEK with a laser wire beam profile monitor. This monitor is based on the Compton scattering process of electrons with a laser light t

A calculation method of emittance growth of an electron beam due to intrabeam scattering is described. The 3 degrees of freedom are equally treated in the beam rest frame, and the couplings between them are included in a natural way. This formalism i

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 (ATF2) provides studies on small beam of nanometer level by utilizing a

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 a high chromaticity level, comparable to that of the Comp
