Description
It has been known since decades that the alignment of a beam of high-energy e- or photons with particular crystal direction involves a huge increase of radiation emission or pair production probability, respectively. While crossing an oriented crystal, such penetrating particles experience an electromagnetic field so strong that it leads to a huge enhancement of the e.m. shower development with consequent reduction of the radiation length. Here we present recent results in this topic, with a focus on materials and configurations suitable for applications in future accelerators/detectors.
The presented results open up several application scenarios in accelerators, e.g. in intense e+ source for the Future Circular Collider, and particle detectors, e.g. in the development of compact forward calorimeters and photo-absorber in fixed-target experiments, as well as in satellite-borne gamma-telescopes.
