  1. 54. Observation of channeling for 6500 GeV/c protons in the crystal assisted collimation setup for LHC
    Dr Walter Scandale (ROMA1)
    28/09/2016, 11:20
    Two high-accuracy goniometers equipped with two bent silicon crystals were installed in the betatron cleaning insertion of the CERN Large Hadron Collider (LHC) during its long shutdown. First beam tests were recently performed at the LHC with 450 GeV/c and 6500 GeV/c stored proton beams to investigate the feasibility of beam halo collimation assisted by bent crystals. For the first time...

  2. 63. Crystal assisted extraction of proton beam from the new FCC injector synchrotron installed within the SPS tunnel

    Oral presentation
    We explore an idea of the use of new superconducting synchrotron placed in the SPS tunnel as the FCC proton injector. The maximum output proton energy will depend on available dipole magnets and can be estimated in the range (1.5 − 3.5) TeV with dipoles from 7 T to 16 T, respectively. The extraction scheme is based on the usage of bent crystal deflectors that could provide beam extraction...

  3. 76. Bent crystals for beam extraction from the LHC
    Andrea Mazzolari (FE)
    28/09/2016, 12:05
    One of the goals of the CRYSBEAM project is to perform a feasibility study of design and manufacturing of bent crystals with a geometry optimised for extraction of the proton or the lead ions beams circulating in the LHC. In the frame of the UA9 experiment, aiming at collimation of the LHC circulating beam by means of channeling in bent crystals, steering of a 6.5 TeV proton beam at an angle...

  4. 22. Measurements of multiple scattering of high energy protons in bent silicon crystals
    Dr Alexander Taratin (Joint Institute for Nuclear Research)
    28/09/2016, 12:20
    The ordered positions of atoms in crystals give a reason to study multiple scattering of high energy charged particles within them. In addition, the accurate representation of multiple scattering of high-energy protons in a bent crystal is important for studies of crystal assisted collimation at the SPS and the LHC. Multiple scattering of 400 GeV/c protons in bent silicon crystals was measured...

  5. 45. Steering efficiency and dechanneling of a Sub-GeV Electron Beam as a Function of Curvature and Energy
    Dr Davide De Salvador (Padova University & INFN-LNL)
    28/09/2016, 12:35
    We report the observation of efficient steering of sub GeV electrons at MAMI (MAinzer MIkrotron) facilities by means of planar channeling and volume reflection in a bent silicon crystal. A 15 μm thick plate of (211) oriented Si was bent to cause quasi-mosaic deformation of the (111) crystallographic planes, which were used for coherent interaction with the electron beam. The plate bending...

  6. 140. State-of-the-art bent silicon crystals for high-energy charged particle beam collimation
    Dr Andrea Mazzolari (FE), Dr Giacomo Germogli (FE)
    28/09/2016, 12:50
    Techniques used at the Sensor and Semiconductor Laboratory of Ferrara for producing strip crystals exploiting anticlastic curvature were recently enhanced by introducing the Magnetorheological Finishing to obtain crystals with ultraflat surface and miscut very close to zero. New materials were employed to realize the holders to fulfill compatibility constraints with the ultra-high vacuum of...
