The proposed Compact Linear Collider (CLIC) is a multi-TeV electron-positron collider for particle physics based on an innovative two-beam acceleration concept. A high-intensity drive beam powers the main of high-frequency (30 GHz) linac with gradient 150 MV/m, by means transfer structure sections. aim CLIC Test Facility (CTF3) to make exhaustive tests parameters and prove technical feasibility. One points particular interest demonstration bunch train compression combination in Delay Loop...
The longitudinal density monitor (LDM) is primarily intended for the measurement of particle population in nominally empty rf buckets. These so-called satellite or ghost bunches can cause problems machine protection as well influencing luminosity calibration LHC. high dynamic range system allows with little 0.01% main bunch at same time characterization bunches. LDM a single-photon counting using visible synchrotron light. photon detector silicon avalanche photodiode operated Geiger mode,...
The AWAKE project at CERN is planned to study proton driven plasma wakefield acceleration. beam from the SPS will be used in order drive wakefields a 10 m long Rubidium cell. In first phase of this experiment, scheduled 2016, self-modulation studied detail, while second an external electron injected into probe acceleration process. installation former CNGS experimental area and required optics flexibility define tight boundary conditions fulfilled by line design. transport low energy (10-20...
Recently we have shown that the asymmetric lateral coherence of betatron radiation is characterized by peculiar properties are evidenced with analysis factor radiation.We extend such results to emitted ultra-relativistic proton beams in a 2-periods undulator.Results 2-dimensional simulation show real substantially improves resolving power, thus transverse beam non-uniformities and size can be measured at large distance.
This paper describes the several phases which led, from conceptual design, prototyping, construction and tests with beam, to installation operation of BRAN (Beam RAte Neutrals) relative luminosity monitors for LHC. The detectors have been operating since 2009 contribute, optimize maintain accelerator performance in two high interaction regions (IR), IR1 (ATLAS) IR5 (CMS). devices are gas ionization chambers installed inside a neutral particle absorber 140 m away Interaction Points monitor...
Charged particle beam diagnostics is a key task in modern and future accelerator installations. The diagnostic tools are practically the ``eyes'' of operators. precision resolution equipment crucial to define performance accelerator. Transition diffraction radiation (TR DR) widely used for electron parameter monitoring. However, those devices determined by how well production, transport detection these types understood. This paper reports on simulations TR DR spatial-spectral characteristics...
A noninvasive, compact laserwire system has been developed to measure the transverse emittance of an ${\mathrm{H}}^{\ensuremath{-}}$ beam and demonstrated at new LINAC4 injector for LHC CERN. Light from a low power, pulsed laser source is conveyed via fiber collide with beam, fraction which neutralized then intercepted by downstream diamond detector. Scanning focused across measuring distribution photo-neutralized particles enables be reconstructed. The vertical phase-space 3 MeV during...
In future high intensity, energy accelerators it must be ensured that particle losses are minimized, as activation of the vacuum chambers or other components makes maintenance and upgrade work time consuming costly.It is imperative to have a clear understanding mechanisms can lead halo formation possibility test available theoretical models with an adequate experimental setup.Measurements based on optical transition radiation (OTR) well-established technique for measurements transverse beam...
