In principle, crystals, if excited by a short pulse bunch or a high power laser, can hold acceleration gradient of 0.1 - 10 TeV/m since they have a few orders of magnitude higher ambient charge density than gas-state plasma. In the effort to prove the concept, we have been planning a feasibility test of beam-driven channeling acceleration with a carbon nanotubes (CNTs) target. This talk will...

As charged particles impinge on atomic planes of a crystalline structure at an angle lower than the so called “critical angle”, planar channeling occurs. Under such condition the particle does not see the material as a disordered medium, and collisions with atoms of the crystal lattice are correlated. Particle is confined between two neighbor atomic planes, and its motion is characterized by...

Proposal on the crystal assisted extraction of halo particles from a new 100 TeV proton collider which is under study in CERN is presented. It is suggested to produce a horisontal dogleg with the Lambertson magnet in a straight section of the collider as it was planned for a Super Fixed Target Beauty Fasility at the SSC. In this case the deflection angle of about 100 μrad or even smaller may...

Phenomenon of deflection of charged particle beam due to channeling in a bent crystal is good investigated and successfully applied for extraction of beam in high-energy accelerators, at the energies of about 10 GeV and higher. However, a big practical interest presents the task of bending and extraction of charged particles with energies below 1 GeV, for example, production of ultrastable...

The mathematical description of focusing of high energy paricles with
the help of bent single crystals are presented. The obtained quations
describe the transformation of two dimensional phase volume of beam
at its motion in a focusing crystal. The carried out measurements of focusing are discussed. The experimental results are compared with our calculations. The possible applications of...

X- and γ-ray detection is currently a hot topic for a wide scientific community, spanning from astrophysics to nuclear medicine. However, lack of optics capable of focusing photons of energies in the energy range 0.1-1 MeV, leaves their detection to a direct-view approach, resulting in a limited efficiency and resolution. The main scope of the INFN-LOGOS project is the development of...
