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…
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…
Strong Enhancement of Electromagnetic Shower Development in Oriented Scintillating Crystals and Implications for Particle Detectors
Mattia Soldani, Pietro Monti-Guarnieri, Alessia Selmi +31
A particle traversing a crystal aligned with one of its crystallographic axes experiences a strong electromagnetic field that is constant along the direction of motion over macrosc…
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…
A highly-compact and ultra-fast homogeneous electromagnetic calorimeter based on oriented lead tungstate crystals
L. Bandiera, V. G. Baryshevsky, N. Canale +25
Progress in high-energy physics has been closely tied to the development of highperformance electromagnetic calorimeters. Recent experiments have demonstrated the possibility to si…
