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

The compact linear accelerator for research and applications (CLARA) is an ultrabright
electron beam test facility being developed at STFC Daresbury Laboratory. The ultimate aim …

In this paper, we systematically study the echo-enabled harmonic generation (EEHG) free
electron laser (FEL). The EEHG FEL uses two modulators in combination with two …

The CERN Large Hadron Collider (LHC) is designed to collide proton beams of
unprecedented energy, in order to extend the frontiers of high-energy particle physics …

The photoinjector test facility at DESY, Zeuthen site (PITZ), was built to develop and optimize
photoelectron sources for superconducting linacs for high-brilliance, short-wavelength free …

MAX IV will be Sweden's next-generation high-performance synchrotron radiation source.
The project has recently been granted funding and construction is scheduled to begin in …

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 …

Since 2015 the LHC has been operating at 6.5 TeV. In 2016 the β-functions at the interaction
points of ATLAS and CMS were squeezed to 0.4 m. This is below the design β*= 0.55 m at 7 …

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 …

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 …
