A family of novel graphite-based composites reinforced with a dispersion molybdenum carbide particles, very high thermal and electrical properties, has been recently developed at CERN, in collaboration Brevetti Bizz (IT), for applications particle accelerators. These materials, produced by spark plasma sintering, assisted liquid phase, have extensively investigated characterized. The influence the initial constituents, together sintering parameters, studied view optimizing thermo-physical...
The international particle physics community considers a Muon Collider (MC) as possible option for the successor of Large Hadron (LHC) at CERN. An collaboration has recently been set up to produce conceptual design study Collider. One main challenges is need an ultra-high magnetic field solenoid final cooling muons. This magnet must have bore aperture about 5 cm and 1% homogeneity over 0.5 m length. CERN exploring possibility developing such by only using stack Rare-earth Barium Copper Oxide...
We describe the magnet challenges for a Muon Collider, an exciting option considered future of particle physics at energy frontier. Starting from comprehensive work performed by US Accelerator Program, we have reviewed performance specifications dictated beam and operating conditions to satisfy accelerator needs. Among many magnets that make up muon collider, identified four systems represent well envelope challenges: target capture solenoid, final cooling dipoles collider dipoles. These...
The rapid interaction of highly energetic particle beams with matter induces dynamic responses in the impacted component. If beam pulse is sufficiently intense, extreme conditions can be reached, such as very high pressures, changes material density, phase transitions, intense stress waves, fragmentation and explosions. Even at lower intensities longer time-scales, significant effects may induced, vibrations, large oscillations, permanent deformation components. These lectures provide an...
The Large Hadron Collider (LHC) is one of the largest scientific instruments ever built. Since opening up a new energy frontier for exploration in 2010, it has gathered global user community working fundamental particle physics and hadronic matter at extreme temperature density. To sustain extend its discovery potential, LHC will undergo major upgrade 2020s. This increase rate collisions by factor five beyond original design value integrated luminosity ten. configuration, known as High...
The introduction at CERN of new extremely energetic particle accelerators, such as the high-luminosity large hadron collider (HL-LHC) or proposed future circular (FCC), will increase energy stored in circulating beams by almost a factor two (from 360 to 680 MJ) and more than 20 (up 8500 MJ), respectively. In this scenario, it is paramount assess dynamic thermomechanical response materials presently used, being developed for use, beam intercepting devices (such collimators, targets, dumps,...
The High-Luminosity Large Hadron Collider (HL-LHC) project aims at extending the operability of LHC by another decade and increasing more than a factor ten integrated luminosity that will have collected end Run 3. This require doubling beam intensity reducing transverse size compared to those design. higher brightness poses new challenges for machine safety, due large energy 700 MJ stored in beams, stability, mainly collimator contribution total coupling impedance. A rich research program...
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges producing collisions at high luminosity and 10 TeV centre mass are being investigated by recently-formed International Muon Collider Collaboration. This Review summarises status recent advances on colliders design, physics detector studies. aim to provide global perspective field outline directions future work.
The problem of collimation and beam cleaning is one the most challenging aspects LHC project. A system must be designed, built, installed commissioned with parameters that extend present state-of-the-art by 2-3 orders magnitude. Problems include robustness, efficiency, impedance operational aspects. strong design effort has been performed at CERN over last two years. adopted phased approach described. Robust precisely controllable collimators have designed. Several prototype built tested...
In view of High Luminosity LHC (HL-LHC) upgrades, collimator materials may become a limit to the machine performance: high RF impedance Carbon-Carbon composites used for primary and secondary collimators can lead beam instabilities, while Tungsten alloy adopted in tertiary exhibits low robustness case beam-induced accidents. An R&D program has been pursued develop new overcoming such limitations. Molybdenum-Graphite, addition its outstanding thermal conductivity, be coated with pure...
Abstract During 2022, a dedicated study was undertaken at CERN, together with the FCC Feasibility Study collaborators, to propose robust configuration for FCC-ee arc half-cell. The proposed layout considers integration aspects of elements in cross section, both booster and collider, as well related powering, cooling ventilation, supporting alignment, optics, instrumentation, handling installation. interfaces between straight sections have also been analysed. This paper summarizes main...

The functional specification of the LHC Collimators requires, for start-up machine and initial luminosity runs (Phase 1), a collimation system with maximum robustness against abnormal beam operating conditions. most severe cases to be considered in mechanical design are asynchronous dump at 7TeV 450GeV injection error. To ensure that collimator jaws survive such accident scenarios, low-Z materials were chosen, driving towards Graphite or Carbon reinforced composites. Furthermore, in-depth...
