    Dr Aakash Sahai (Univ. of Colorado Denver)
    10/03/2020, 11:20

    Atomic-scale TV/m wakefields in fiber-like nanostructured tubes are elucidated to be realizable using nonlinear tube surface electron “crunch-in” oscillations. Effective excitation of surface crunch-in oscillations as tube wakefields can sustain electron density waves with wavebreaking fields that offer many GeV energy gain in sub-millimeter nanostructured tube modules. A proof-of-principle...

    Laura Bandiera (Universita e INFN, Ferrara (IT))
    10/03/2020, 15:45

    Channeling and coherent interactions of charged particles in crystals have been known since the 60s and used as a tool for material analysis by low-energy ion channeling and for the generation of linearly polarized γ-beams through coherent bremsstrahlung at electron accelerators. Here, we report on a series of experiments carried out at the MAinzer MIkrotron with the aim of investigating the...

  13. 22. Insight into axial channeling for particle steering
    Vincenzo Guidi (Universita e INFN, Ferrara (IT))
    10/03/2020, 17:05

    Axial channeling consists of coherent orientational interaction of charged particles with the strings of a crystal. In contrast to more known planar channeling, for which particle interaction occurs with the planes, axial channeling occurs with particle trajectory is nearly aligned with the lattice strings. In the case of a bent crystal, chaotic scattering on atomic strings is the basis of...

  14. 24. Silicon crystals for steering of high-intensity particle beams at ultra-high energy accelerators
    Andrea Mazzolari (Universita e INFN, Ferrara (IT)), Marco Romagnoni (Universita e INFN, Ferrara (IT))
    10/03/2020, 17:30

    Simulation models and worldwide experimental campaigns shows that coherent interactions between charged particle beam and crystals can be exploited at high-intensity particle beams at ultra-high energy accelerators for efficient particle beam steering. Indeed, a properly shaped tiny silicon crystal can deliver the same steering effect which would be delivered by a multi hundred Tesla dipole....

  18. 21. Numerical investigation of beam-driven wakefields in hollow plasma channels modelled with carbon ions
    Mr Alexandre Bonatto (University of Manchester)
    11/03/2020, 11:30

    Hollow plasma channels can be modelled as shells of heavy ions, populated by pre-ionised electrons. Although this model does not take into account the crystalline structure of a solid, hence neglecting the properties emerging from such structure, it is adopted here as a simplistic approximation of a carbon nanotube (CNT). This approach allows for the investigation of beam--driven wakefields...
