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…
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…
Coherent radiation in axially oriented industrial-grade tungsten crystals: A viable path for an innovative γ-rays and positron sources
N. Canale, M. Romagnoni, A. Sytov +18
It is known that the alignment of an high-energy e- beam with specific crystal directions leads to a significant increase of the coherent radiation emission. This enhancement can b…
