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...

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...

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...

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...

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...
