invited

Channeling is the phenomenon well-known in the physics world mostly related to the motion of the beams of charged particles in aligned crystals. Since the beginning of 1970s channeling of high-energy leptons (electrons/positrons of several MeV up to hundred GeV energies) and hadrons (protons/ions of tens GeV up to several TeV energies) has been applied at various famous world research centres...

oral

Crystal-based extraction using a bent crystal has been already applied at several high-energy hadron accelerators, but has never been applied for electrons. However, this technique can be very promising for synchrotron light sources and for existing and future lepton collider projects as well for nuclear and particle physics detectors and generic detector R&D and in many projects in...

oral

In this work we propose a relatively simple model for taking into account the medium crystallinity in GEANT4. The model includes a simplified method for crystallinity description by changing cross-sections of the physical processes without microscopic motion simulation of the charged particles in channeling mode. The cross-sections for processes of Bremsstrahlung and the electron-positron pair...

oral

The design of innovative applications of electromagnetic interactions of charged particles interactions with oriented crystals in accelerator physics, detector physics, astrophysics, nuclear physics and radiation therapy requires extensive and reliable simulation tool to simulate in details all the experimental setup. Therefore, the implementation of the physics of channeling and radiation in...

78. Recent developments of the FLUKA Channeling model and benchmarking of SPS and LHC crystal-related activities

oral

In recent years, bent crystals have become a mature technology now exploited in several applications at CERN, such as shadowing techniques to reduce particle losses during slow extraction from the SPS as well as crystal-assisted collimation for LHC ion runs. Looking forward, they are also a key component of future plans to measure the electric and magnetic dipole moments of short-lived...
