We observed a substantial increase of the scintillation light output of lead tungstate (PbWO$_4$) at a small incidence angle with respect to two main lattice axes. [...]

Steering efficiency of a ultrarelativistic proton beam in a thin bent crystal / Bagli, Enrico (INFN, Ferrara ; Ferrara U.) ; Bandiera, Laura (INFN, Ferrara ; Ferrara U.) ; Guidi, Vincenzo (INFN, Ferrara ; Ferrara U.) ; Mazzolari, Andrea (INFN, Ferrara ; Ferrara U.) ; De Salvador, Davide (INFN, Legnaro ; Padua U.) ; Berra, Alessandro (Insubria U., Como ; INFN, Milan Bicocca) ; Lietti, Daniela (Insubria U., Como ; INFN, Milan Bicocca) ; Prest, Michela (Insubria U., Como ; INFN, Milan Bicocca) ; Vallazza, Erik (INFN, Trieste)
Crystals with small thickness along the beam exhibit top performance for steering particle beams through planar channeling. For such crystals, the effect of nuclear dechanneling plays an important role because it affects their efficiency. [...]

Deflection of 400  GeV/c proton beam with bent silicon crystals at the CERN Super Proton Synchrotron / Scandale, Walter (CERN) ; Carnera, Alberto ; Della Mea, Gianantonio ; De Salvador, Davide ; Milan, Riccardo ; Vomiero, Alberto ; Baricordi, Stefano ; Dalpiaz, Pietro ; Fiorini, Massimiliano ; Guidi, Vincenzo et al.
This paper presents a detailed study of the deflection phenomena of a 400  GeV/c proton beam impinging on a new generation of bent silicon crystals; the tests have been performed at the CERN Super Proton Synchrotron H8 beam line. Channeling and volume reflection angles are measured with an extremely precise goniometer and with high resolution silicon microstrip detectors. [...]

Double volume reflection of a proton beam by a sequence of two bent crystals / Scandale, Walter (CERN) ; Carnera, Alberto (INFN, Legnaro ; Padua U.) ; Della Mea, Gianantonio (INFN, Legnaro ; Trento U.) ; De Salvador, Davide (INFN, Legnaro ; Padua U.) ; Milan, Riccardo (INFN, Legnaro) ; Vomiero, Alberto (INFN, Legnaro ; INFM, Brescia) ; Baricordi, Stefano (INFN, Ferrara) ; Dalpiaz, Pietro (INFN, Ferrara) ; Fiorini, Massimiliano (INFN, Ferrara) ; Guidi, Vincenzo (INFN, Ferrara) et al.
The doubling of the angle of beam deflection due to volume reflection of protons by a sequence of two bent silicon crystals was experimentally observed at the 400 GeV proton beam of the CERN SPS. A similar sequence of short bent crystals can be used as an efficient primary collimator for the Large Hadron Collider..

High-Efficiency Volume Reflection of an Ultrarelativistic Proton Beam with a Bent Silicon Crystal / Scandale, Walter (CERN) ; Still, Dean A ; Carnera, Alberto ; Della Mea, Gianantonio ; De Salvador, Davide ; Milan, Riccardo ; Vomiero, Alberto ; Baricordi, Stefano ; Dalpiaz, Pietro ; Fiorini, Massimiliano et al.
The volume reflection phenomenon was detected while investigating 400 GeV proton interactions with bent silicon crystals in the external beam H8 of the CERN Super Proton Synchrotron. Such a process was observed for a wide interval of crystal orientations relative to the beam axis, and its efficiency exceeds 95%, thereby surpassing any previously observed value. [...]
