The Large Hadron electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) energy and intensity frontier particle physics. Exploiting recovery technology, it collides a novel, intense beam with proton or ion from High Luminosity--Large (HL-LHC). accelerator interaction region are for concurrent electron-proton proton-proton operation. This report represents an update Conceptual Design Report (CDR) LHeC, published in 2012. It comprises new results on parton...
This document summarizes the work of Accelerator Working Group (AWG) International Scoping Study (ISS) a Future Neutrino Factory and Superbeam Facility. The main goal activity was to reach consensus on baseline design for complex, including proton driver parameters, choice target, front-end design, acceleration system decay ring geometry. Another explore commonality, if any, between those or Beta Beam facility. In general, requirements either latter facilities are less stringent than...
The construction of a 4 GeV superconducting proton linac (the SPL) is now part the long term plan CERN, and Linac4, its low-energy front end, has begun. For mid-2012 existing conceptual design SPL to be refined transformed into project proposal. As first step, basic parameters like rf frequency, accelerating gradient, operating temperature cavities have been reassessed, taking account experience accumulated in world during recent years, especially for Spallation Neutron Source (SNS) Oakridge...
Abstract The FCC-ee machines present a huge challenge for the RF systems, which need to be adapted very diverse beam conditions going from moderate energy and high current Z machine low ttbar. This inverse scaling results naturally fixed budget synchrotron radiation, SRF cavities compensate. A global solution was elaborated FCC Conceptual Design Report (Abada in Eur Phys J Spec Top 228):261–623, 2019), is referred here as baseline. Recently, further studies have led new optimized baseline,...
The Neutrino Factory is a new concept for an accelerator that produces high-intensity, high-energy beam of electron and muon neutrinos – the ultimate tool neutrino oscillation studies only machine conceived up today could help detect CP violation leptons. basic production from decay muons. Due to their short lifetime, these muons have be accelerated very fast. Several techniques, like high-intenstiy proton linac, high-power targets, ionization cooling or recirculating linacs are required....
Higher order modes (HOMs) can severely limit the operation of superconducting cavities in a linear accelerator with high beam current, duty factor, and complex pulse structure. The full HOM spectrum has to be analyzed identify potentially dangerous already during design phase define their damping requirements. For this purpose dedicated simulation code higher mode dynamics (SMD) focused on beam-HOM interaction was developed, taking into account important effects like frequency spread, input...

The particle-core model for a continuous cylindrical beam is used to describe the motion of single particles oscillating in uniform linear focusing channel. Using random variation forces, deployed as proof principle occurrence large particle radii without presence initial mismatch core. Multiparticle simulations periodic 3D transport channel are then qualify and quantify effects realistic accelerator lattice.
Superconducting rf (SRF) cavities are traditionally fabricated from superconducting material sheets or made of copper coated with material, followed by trim machining and electron-beam welding. An alternative technique to traditional shaping methods, such as deep-drawing spinning, is electrohydraulic forming (EHF). In EHF, half-cells obtained through ultrahigh-speed deformation blank sheets, using shockwaves induced in water a pulsed electrical discharge. With respect highly dynamic process...
Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at interaction point (IP). A first demonstration experiment of with hadron beams was successfully carried out high energy protons. This breakthrough result is fundamental achieve physics goals LHC (HL-LHC) and circular collider (FCC). The expected peak gain (related collision rate) 65% for HL-LHC even greater FCC. Novel experiments proton in CERN's Super Proton...
The ISIS spallation neutron source has been running successfully for more than 15 years and at 160 kW remains the most powerful of its kind in world. With machines due to operate or near megawatt level under construction United States Japan expected come on line within next decade, advances Europe have not progressed same rate. A positive decision European Spallation Source (ESS) looks unlikely one is led consider feasibility alternative options. An upgrade such possibility. current...
