invited

The injection of a seed to initiate the FEL amplification in a free electron laser is a concept initially introduced to improve the source spectral brightness. This concept was first demonstrated at BNL (USA). A few experiments carried out later have shown the possibility to extend the method to reach VUV wavelengths and FERMI was built as a facility exploiting these methods to provide to...

oral

Plasma wakefield acceleration in oriented structured solids (nanotubes and crystals) has a potential of extremely high acceleration gradients exceeding 1 TeV/m. One can exploit the nuclei-free space in nanotubes and crystals both to produce plasma waves and to accelerate channeling particles being contained within their channel and moving almost without collisions with ions.

In this work we...

10. Reduction of multiple scattering of positively charged ultrarelativistic particles channeling in planar fields of single crystals

oral

Recently the effect of reduction of multiple scattering of positively charged particles was observed at channeling in bent (111) and (110) planes of silicon. The effect is observed in the plane orthogonal to the bending plane. The degree of reduction of rms scattering angle channeling particles (in comparing with equivalent amorphous media) reached up to 8 times. The analytical theory of...

85. Operational experience, recent developments and plans for crystal collimation at the LHC

oral

The concept of crystal collimation exploits the peculiar properties of crystalline materials to deflect high-energy beam halo particles at angles orders of magnitude larger than what can be achieved with scattering by conventional materials used as primary collimators. This innovative technique is planned to be used to improve the collimation efficiency with heavy-ion beams at the Large Hadron...

45. Electron Emission Channeling for lattice location of radioactive isotopes in single crystals: Improvements from a Timepix3 quad detector and new PyFDD data analysis software

Eric David Bosne

06/06/2023, 10:30

oral

Electron Emission Channeling is a technique used for the measurement of the lattice location of radioactive isotopes implanted into single crystals. This work reports on how a Timepix3 detector was installed in the experimental setup and the resulting advantages of doing so. It also reports on the data analysis and software updates that were necessary to accompany the increase in data, and...

12. Accelerator based Neutron Source VITA

Sergey Taskaev

invited

The report describes the accelerator based neutron source VITA that provides beams of protons, deuterons, neutrons, photons, alpha particles and positrons for a wide range of studies, present and discuss the results obtained, and declare plans.
