Observation of narrow-band radiation from a boron-doped diamond superlattice with an 855 MeV electron beam
Hartmut Backe, José Baruchel, Simon Bénichou +8
We report the first observation of narrow band 1.3 MeV radiation from a crystalline diamond micro-undulator. A diamond superlattice was grown with a periodical varying boron d…
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…
Planar channeling of 855 MeV electrons in a boron-doped (110) diamond undulator -- a case study
H. Backe, W. Lauth, P. Klag +1
A 4-period diamond undulator with a thickness of 20 m was produced with the method of Chemical Vapour Deposition (CVD), applying boron doping, on a straight diamond crystal wit…
