“…In this case the characteristics of undulator radiation are practically independent on channeling oscillations [3,4], and the operational principle of a crystalline undulator is the same as for a conventional one (see, e.g., [58][59][60][61][62]) in which the monochromaticity of radiation is the result of constructive interference of the photons emitted from similar parts of trajectory, see In this case the characteristics of undulator radiation are practically independent on channeling oscillations [3,4], and the operational principle of a crystalline undulator is the same as for a conventional one (see, e.g., [58][59][60][61][62]) in which the monochromaticity of radiation is the result of constructive interference of the photons emitted from similar parts of trajectory, see …”

“…Good efficiency of deflection, up to 80% was achieved, but deflection angle was limited because of non-optimal construction of first crystal device. For optimization of crystal targets we propose a research about the deflection of particles in the Beam Test Facility of the LNF INFN, where a particle beam with energies of 50-700 MeV is readily available [5]. The necessary experimental facility contains a remote controlled goniometer for installation of crystal targets, beam collimator and detector.…”

Steering of sub- GeV charged particle beams by use of reflections in thin crystal targets

The phenomenon of deflection of a charged particle beam due to channeling in a bent crystal has been well investigated and successfully applied for beam extraction at high-energy accelerators, for energies about 10 GeV and higher. However, it is of a big practical interest to consider the task of bending and extracting charged particles with energies below 1 GeV, for example, for production of ultrastable beams of low emittance for medical and biological applications. However, for low energy, i.e. below 1 GeV, the bent crystal channeling is not efficient. That motivates us to consider in this article an other crystal technique, based on thin straight crystal targets, as elements for the extraction and collimation of the circulating beam in an accelerator ring. The main advantages of reflection in straight crystals, in comparison with bent crystal channeling, consist in the small length of straight crystals along the beam, that reduces the amount of nuclear interactions and improves the background.

“…Such hybrid materials are of great practical interest because of their improved thermal conductivity, radiation resistance, electrical insulation of thermoplastics, and thermal performance [5][6][7][8][9]. Obtained hybrid nanocomposites based on organic semiconductors, ferroelectric and magnetic materials are used in light emitting devices, lighting holders, various electronic devices, motors and battery casing, temperature sensors and optimized heat exchangers [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”
