Abstract
The paper considers the polarization radiation that occurs when an ultrarelativistic electron passes through a fractal cluster. The characteristics of radiation from clusters of different sizes constructed using the diffusion limited aggregation algorithm are numerically calculated. The transformation of the polarization radiation pattern is traced depending on the number of particles in the cluster. The evolution of the asymmetry formation “forward–backward” is clearly observed with an increase in the number of particles making up the fractal cluster.
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.
