Description
Oriented crystals create a unique environment for high-energy charged particles and photons. When charged particles undergo channeling * , they are guided by atomic electric fields with angstrom-level precision, similar to accelerator optics and achieving effects equivalent to magnetic fields exceeding 100 T. This process also generates intense X-ray and gamma radiation due to transverse e+/e- oscillations and reduces radiation length by up to a factor of 5 ** . Furthermore, crystals and nanostructures are the key materials for plasma wakefield acceleration in solid-state targets, achieving gradients over 1 TeV/m.
These properties enable innovative applications, including instruments for crystal-based beam manipulation and beam focusing; X-ray and gamma sources for cancer radiotherapy, nuclear spectroscopy, and radioisotope production; positron sources for future lepton colliders; compact crystalline calorimeters for HEP experiments; and plasma wakefield acceleration for future colliders.
This presentation offers a comprehensive overview of these applications and introduces the Geant4 G4ChannelingFastSimModel * , which enables simulation-driven design for their development.
