Satellite-borne -ray astrophysics from coherent interactions in oriented crystals
Pietro Monti-Guarnieri, Gianfranco Paternò, Alexei Sytov +20
High-density and high-Z crystals are key elements of most space-borne -ray telescopes operating at gigaelectronvolt energies (such as Fermi-LAT). The lattice structure is usual…
Investigation of Radiation Emitted by Sub GeV Electrons in Oriented Scintillator Crystals
L. Bandiera, R. Camattari, N. Canale +12
The research investigates coherent interactions between sub-GeV electrons and oriented scintillator crystals, leading to enhanced electromagnetic (EM) radiation. Experiments at Mai…
Observation of Fine Structure in Channeling of Particles in Bent Crystals
A. Mazzolari, H. Backe, L. Bandiera +14
We observed highly efficient manipulation of the 530 MeV positron beam at Mainz Microtron via bent crystals. The low beam divergence revealed a fine structure in the angular distri…
Beam Steering and Radiation Generation of Electrons in Bent Crystals in the Sub-GeV Domain
R. Negrello, M. Romagnoni, A. Sytov +15
We present an investigation into beam steering and radiation emission by sub-GeV electrons traversing bent silicon crystals. Using 855, 600, and 300~MeV electron beams at the Mainz…
R&D on a high-performance electromagnetic calorimeter based on oriented crystalline scintillators
M. Soldani, N. Argiolas, L. Bandiera +36
Although inorganic scintillators are widely used in the design of electromagnetic calorimeters for high-energy physics and astrophysics, their crystalline nature and, hence, their…
High-Precision Alignment Techniques for Realizing an Ultracompact Electromagnetic Calorimeters Using Oriented high-Z Scintillator Crystals
Lorenzo Malagutti, Alessia Selmi, Laura Bandiera +29
Electromagnetic calorimeters used in high-energy physics and astrophysics rely heavily on high-Z inorganic scintillators, such as lead tungstate (PbWO4 or PWO). The crystalline str…
