Abstract

We present the results of the experimental study of the Zero-Degree Focusing effect appearing in the transmission of MeV proton beam through a

200

nm long

⟨ 100 ⟩

axial channels of

S i

crystal, which is characterized by a large maximum in the zero-degree yield at and by a

45 °

rotation of the angular distribution in the scattering angle plane happening after the Zero-Degree Focusing point. We will show that observed experimental results can be explained fully in the framework of the theory of rainbows.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
