1 The CpFM, an in-vacuum Cherenkov beam monitor for UA9 at SPS
  This paper collects the description of the construction of a version of the Cherenkov screen (dubbed Cherenkov proton flux monitor) installed into the SPS ring to monitor the particles extracted by a bent crystal
2 Nuclear interaction detector system for UA9 experiments based on ArduSiPM prototype
  presented at IEEE 2015 conference in San Diego
3 WIMP detection and slow ion dynamics in carbon nanotube arrays
  ref: Eur.Phys.J. C76 (2016) no.6, 349
  A more refined insight of the idea developed in a previous paper about using carbon nanotubes as target for cosmic dark matter particles. Analytical results and Monte Carlo simulations are reported showing that channeling in carbon nanotubes can be efficiently exploited.
4 High-efficiency deflection of high energy protons due to channeling along the 〈110〉 axis of a bent silicon crystal
  ref: Phys.Lett. B 760 (2016) 826
  Understanding the detailed nature of coherent interaction in crystals is of fundamental importance, especially for the parasitic operation of a crystal kicker. In this paper a comparative study of hadronic inelastic interaction of a proton with an aligned crystal is reported. The axial orientation seems to offer a reduced rate of interaction (and therefore losses in an accelerator) compared to planar orientation. In future this could be used for novel generation of crystal kicker even more performing.
5 Observation of channeling for 6500 GeV/ c protons in the crystal assisted collimation setup for LHC
  ref: Phys.Lett. B758 (2016) 129-133
  This is the first demonstration that a multi-TeV hadron beam can be effectively extracted from the main circulating beam at the LHC.The kick imparted by the crystal is still very small (50 microrad) compared to the final requirement for full extraction from the beam pipe,nevertheless this the first experimental demonstration that a piezo-goniometer orienting a strip crystal into the beam is able to channel 6500 GeV/ c protons with high efficiency. CRYSBEAM team took part to this by providing the strip crystal used in this measurement.

7 Carbon Nanotubes Potentialities in Directional Dark Matter Searches (published version)
  ref: Physics of the Dark Universe, Vol. 9–10 (2015) 24
  Expertise on charged particle coherent interaction has inspired G.Cavoto to suggest use of channeling in carbon nanotubes to find evidence of one the most mysterious component of our universe, that is dark matter weakly interacting particles moving in our galaxy as almost invisible mostly neutral cosmic rays.
8 Observation of strong leakage reduction in crystal assisted collimation of the SPS beam
  ref: Physics Letters B, Volume 748, 2 September 2015, Pages 451–454
  CRYSBEAM team took part in a campaign of testing moderately bent crystal with the SPS proton beam. This paper reports fundamental results demonstrating how a crystal oriented in channeling mode induce little losses in the accelerator. This is of critical importance for the use of a crystal to extract parasitically the beam, that is the main goal of the CRYSBEAM research.
