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,...
Abstract Two new absorbing materials were developed as collimator inserts to fulfil the requirements of HL-LHC higher brightness beams: molybdenum-carbide graphite (MoGr) and copper-diamond (CuCD). These tested under intense beam impacts at CERN HiRadMat facility in 2015, when full jaw prototypes irradiated. Additional tests performed 2017 on another series material samples, including also improved grades MoGr CuCD, different coating solutions. This paper summarizes main results two...
Abstract The ever-expanding requirements of high-power targets and accelerator equipment has highlighted the need for facilities capable accommodating experiments with a diverse range objectives. HiRadMat, High Radiation to Materials testing facility at CERN has, throughout operation, established itself as global user going beyond its initial design goals. Pulsed high energy, intensity, proton beams have been delivered ranging from materials testing, detector's prototype validation,...
The addition of silicon ions to hydroxyapatite (HA) provides a more inorganic bone-like chemical composition compared stoichiometric HA. It is known aid the bioactivity material and improve rates osseointegration, osteoconduction bone mineralisation. literature, however, lacks detailed information regarding each step aqueous precipitation procedure produce silicon-substituted HA (Si-HA). current work utilised Raman spectroscopy at stage method determine how silicate incorporated into...
Various graphite targets with a tantalum core were exposed to 440 GeV pulsed proton beams at the HiRadMat facility CERN. The dynamic response was investigated by monitoring surface velocity of samples laser Doppler vibrometry. study comprises different grades, such as polycrystalline, expanded and carbon-fiber reinforced graphite, low-density graphitic foams, all candidates for beam-intercepting devices in high-power accelerators. purpose is concentrate large energy deposition this...
HiRadMat is a unique user facility providing controlled test environment for accelerator experiments investigating the effects of high energy, intensity proton beam.HiRadMat uses 440 GeV/c beam fastly-extracted from CERN SPS and can currently provide maximum pulse 3.5 × 10 13 protons.Initially designed to explore damage thresholds components which experienced thermal shocks induced by high-brightness beams, has continued advance into new areas research.This contribution will focus on...
