Multiple scattering of positively charged particles moving near the (111) plane in a silicon single crystal / Scandale, W (Imperial Coll., London) ; Cerutti, F (CERN) ; Esposito, L S (CERN) ; Garattini, M (CERN) ; Gilardoni, S (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Mirarchi, D (CERN) ; Redaelli, S (CERN) ; Smirnov, G (CERN) et al.
The article is devoted to the study of the suppression of multiple scattering of positively charged particles with momenta of 180 GeV/c and 400 GeV/c passing through bent single crystals of silicon at small angles to the plane (111) both in channeling mode and in the above-barrier state. For the first time, the suppression of the effect of multiple scattering of non-channeling particles passing at a small angle to one of the planes of a silicon single crystal was observed. [...]

Channeling performance of bent crystals developed at CERN / Rodin, Volodymyr (CERN) ; Esposito, Luigi Salvatore (CERN) ; Lechner, Anton (CERN) ; Demassieux, Quentin (CERN) ; Matheson, Eloise (CERN) ; Solis Paiva, Santiago (CERN) ; Seidenbinder, Regis (CERN) ; Aberle, Oliver (CERN) ; Perillo Marcone, Antonio (CERN) ; Calviani, Marco (CERN) et al.
Bent crystals are a mature technology used in several applications at CERN, such as the crystal-assisted collimation system for LHC ion operation and reduction of losses during the slow extraction from the SPS by shadowing the electrostatic septum. In the future, it is planned to measure electric and magnetic dipole moments of short-lived particles with a double-crystal experiment in the LHC. [...]

Operational performance of crystal collimation with 6.37 $Z$ TeV Pb ion beams at the LHC / D'Andrea, M (CERN) ; Aberle, O (CERN) ; Bruce, R (CERN) ; Butcher, M (CERN) ; Di Castro, M (CERN) ; Cai, R (CERN) ; Lamas, I (CERN) ; Masi, A (CERN) ; Mirarchi, D (CERN) ; Redaelli, S (CERN) et al.
The concept of crystal collimation relies on the use of bent crystals to coherently deflect positively charged particles with suitable impact conditions by trapping them in the potential well generated by adjacent crystalline planes. The resulting deflection is much higher than what can be achieved by multiple scattering on amorphous materials. [...]

Beam merging assisted by a bent crystal / Scandale, W (Imperial Coll., London ; INFN, Rome) ; Cerutti, F (CERN) ; Esposito, L S (CERN) ; Gilardoni, S (CERN) ; Losito, R (CERN) ; Smirnov, G I (CERN) ; Giribono, A (Frascati) ; Bauce, M (INFN, Rome) ; Collamati, F (INFN, Rome) ; Valente, P (INFN, Rome) et al.
Bunch merging is a well-established technique to increase the intensity of synchrotrons and the luminosity of circular colliders. We suggest to exploit a combination of channeling, volume reflection and amorphous interactions in a bent crystal for beam merging in a transfer line. [...]

Track reconstruction and analysis of particle interactions in short bent crystals / Rossi, R (CERN ; Imperial Coll., London) ; Esposito, L S (CERN) ; Pesaresi, M (Imperial Coll., London) ; Hall, G (Imperial Coll., London) ; Scandale, W (Imperial Coll., London ; INFN, Rome)
Measurements of the interaction of positively charged particles with bent crystals wereobtained by developing a new and consolidated analysis method, for the use of UA9 collaboration.The method was deployed to characterize crystals with a length of a few mm along the beamdirection and a bending angle in the order of 10 μrad to 100 μrad, typicallyexploited in the CERN accelerators. To assess their properties and quality, the crystals havebeen investigated in the Super Proton Synchrotron North Area with a beam of mixed hadrons at180 GeV. [...]

HL-LHC layout for fixed-target experiments in ALICE based on crystal-assisted beam halo splitting / Patecki, Marcin (Warsaw U. of Tech.) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN) ; Fomin, Alex (CERN) ; Hadjidakis, Cynthia (IJCLab, Orsay) ; Galluccio, Francesca (INFN, Naples) ; Scandale, Walter (Imperial Coll., London ; INFN, Rome)
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) is the world's largest and most powerful particle accelerator colliding beams of protons and lead ions at energies up to 7 ZTeV, Z is the atomic number. ALICE is one of the detector experiments optimised for heavy-ion collisions. [...]

Dechanneling of high energy particles in a long bent crystal / Scandale, W (CERN) ; Arduini, G (CERN) ; Cerutti, F (CERN) ; Garattini, M (CERN ; Imperial Coll., London) ; Gilardoni, S (CERN) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Mirarchi, D (CERN) ; Montesano, S (CERN) et al.
Experimental results on deflection of a 180 GeV/c $\pi^+$-meson beam by a 23 mm long bent silicon crystal are analyzed to study the dechanneling process of particles due to multiple scattering. A new approach for the determination of contributions from atomic nuclei and electrons to the multiple scattering using the experimental data for random crystal orientations is suggested. [...]

Feasibility of crystal-assisted collimation in the CERN accelerator complex / UA9 Collaboration
Bent silicon crystals mounted on high-accuracy angular actuators were installed in the CERN Super Proton Synchrotron (SPS) and extensively tested to assess the feasibility of crystal-assisted collimation in circular hadron colliders. The adopted layout was exploited and regularly upgraded for about a decade by the UA9 Collaboration. [...]

Multiple scattering of channeled and non-channeled positively charged particles in bent monocrystalline silicon / Scandale, W. (CERN) ; Arduini, G. (CERN) ; Cerutti, F. (CERN) ; Esposito, L.S. (CERN) ; Garattini, M. (CERN) ; Gilardoni, S. (CERN) ; Losito, R. (CERN) ; Masi, A. (CERN) ; Mirarchi, D. (CERN) ; Montesano, S. (CERN) et al.
We present the results of an experimental study of multiple scattering of positively charged high energy particles in bent samples of monocrystalline silicon. This work confirms the recently discovered effect of a strong reduction in the rms multiple scattering angle of particles channeled in the silicon (111) plane. [...]
