The conversion of the CALIFES beamline CTF3 into “CERN Linear Electron Accelerator for Research” (CLEAR) facility was approved in December 2016. primary focus CLEAR is general accelerator R&D and component studies existing possible future applications. This includes high gradient acceleration methods, e.g. CLIC plasma technology, prototyping validation components, HL-LHC upgrade. also provides irradiation test capabilities characterisation electronic components medical A description with...
A prototype 11.994 GHz, traveling-wave accelerating structure for the Compact Linear Collider has been built, using novel technique of assembling from milled halves. The use halves many advantages when compared to a made individual disks. These include potential reduction in cost, because there are fewer parts, as well greater freedom choice joining technology no rf currents across halves' joint. Here we present design and fabrication structure, followed by results high-power test post-test...
The PolariX TDS (Polarizable X-Band Transverse Deflection Structure) is an innovative TDS-design operating in the X-band frequency-range. design gives full control of streaking plane, which can be tuned order to characterize projections beam distribution onto arbitrary transverse axes. This novel feature opens up new opportunities for detailed characterization electron beam. In this paper we present first measurements Polarix at FLASHForward beamline DESY, including three-dimensional...
Abstract The Compact Linear Collider (CLIC) beam-based acceleration baseline uses high-gradient travelling wave accelerating structures at a frequency of 12 GHz. In order to prove the performance these high peak power and short pulse width RF, two klystron-based test facilities will be put in operation this year. first Southern Hemisphere X-band Laboratory for Accelerators Beams (X-LAB) is currently being commissioned University Melbourne, it house half CERN stand XBOX3, which has been...
Longitudinal electron-beam diagnostics play a critical role in the operation and control of x-ray free-electron lasers, which rely on parameters such as current profile, longitudinal phase space, or slice emittance particle distribution. On one hand, femtosecond-scale electron bunches produced at these facilities impose stringent requirements resolution achievable with diagnostics. other, research development novel accelerator technologies beam-driven plasma-wakefield accelerators (PWFA)...
A collaboration between DESY, PSI and CERN has developed built an advanced modular X-band transverse deflection structure (TDS) system with the new feature of providing variable polarization deflecting force. The prototype novel TDS, polarizable (PolariX) was fabricated at following high-precision tuning-free production process for C-band Linac SwissFEL project. Bead-pull rf measurements were also performed to verify, in particular, that dipole fields does not have any rotation along...
