Measurement and correction of charged particle beam optics have been a major concern
since the advent of strong focusing synchrotron accelerators. Traditionally, particle colliders …

This review paper describes the energy-upgraded Continuous Electron Beam Accelerator
Facility (CEBAF) accelerator. This superconducting linac has achieved 12 GeV beam energy …

The LHC is currently operating with a proton energy of 4 TeV and β* functions at the ATLAS
and CMS interaction points of 0.6 m. This is close to the design value at 7 TeV (β*= 0.55 m) …

Coherent transition radiation (CTR) in the THz regime is an important diagnostic tool for
analyzing the temporal structure of the ultrashort electron bunches needed in ultraviolet and …

Optics stability during all phases of operation is crucial for the LHC. Tools and procedures
have been developed for rapid checks of beta beating, dispersion, and linear coupling, as …

The integrated luminosity, a key figure of merit for any particle-physics collider, is closely
linked to the peak luminosity and to the beam lifetime. The instantaneous peak luminosity of …

An accelerator-driven subcritical system (ADS) program was launched in China in 2011,
which aims to design and build an ADS demonstration facility with the capability of more …

Monte Carlo shower simulations are essential for understanding and predicting the
consequences of beam losses in high-energy proton and ion colliders. Shower simulations …

The Metrology Light Source is a recently constructed 630 MeV electron storage ring,
operating as a synchrotron radiation source for the THz to extreme UV spectral range. It is …

The China initiative Accelerator-Driven subcritical System (CiADS) project aims to design
and build the world's first accelerator-driven subcritical system demonstration facility. The …
