| Popis: | FAMA is a user facility for materials science with low energy ions beams in the Vinca Institute of Nuclear Sciences, Belgrade, Serbia. It includes a heavy ion source, a light ion source, two channels for modification of materials, and two channels for analysis of materials. Recently, designing of a channel for transmission studies within FAMA, the C3 channel, has begun. The initially planned studies are related to the rainbow effects with electrostatic very thin lenses (VTLs) and two-dimensional (2D) materials. In the former case, the main aim is to develop a method for generation of narrow ion beams, to be used, for example, in materials science and technology. The main aim in the latter case is to determine precisely the interaction potential of the projectile and target atoms. In both cases, the theoretical basis of the explorations is the theory of crystal rainbows. From the technological point of view, construction and use of the C3 channel includes the following challenges: (i) production and diagnostics of the narrow and parallel ion beams to be directed to the chosen VTLs and 2D materials, (ii) registration of the transmitted ion beams with high resolution 2D position sensitive detectors, (iii) preparation of the 2D materials and maintaining their cleanliness during the measurements, and (iv) providing the ultra-high vacuum conditions in measurements with the 2D materials.
