A novel scheme for the focusing of high-energy leptons in future linear colliders was
proposed in 2001 [P. Raimondi and A. Seryi, Phys. Rev. Lett. 86, 3779 (2001)]. This scheme …

We present recent achievements in the application of optical diffraction radiation (ODR) to
the measurement of the transverse beam size of a 1.3 GeV micrometer-size electron beam …

A high-resolution, low-latency beam position monitor (BPM) system has been developed for
use in particle accelerators and beam lines that operate with trains of particle bunches with …

We developed an electron beam size monitor for nanometer scaled beam sizes. It uses a
laser interference fringe for a scattering target with the electron beam. The target beam size …

A high-resolution, intratrain position feedback system has been developed to achieve and
maintain collisions at the proposed future electron-positron International Linear Collider …

We report the design, operation, and performance of a high-resolution, low-latency, bunch-
by-bunch feedback system for nanobeam stabilization. The system employs novel, ultralow …

A high-precision intra-bunch-train beam orbit feedback correction system has been
developed and tested in the ATF2 beamline of the Accelerator Test Facility at the High …

To achieve the design luminosity at future linear colliders, control of beam stability at the sub-
nanometre level at the interaction point will be necessary. Any source of beam motion which …

The main physics programme of the International Linear Collider (ILC) requires a
measurement of the beam energy at the interaction point with an accuracy of 10-4 or better …

Abstract The Accelerator Test Facility 2 (ATF2) in KEK, Japan, is a prototype scaled
demonstrator system for the final focus required for a future high energy lepton linear …
