The energy of the particles in this case can reach tens of MeV per nucleon, which is comparable with the energy of a small accelerator. A beam of particles can be used as initiators of a thermonuclear reaction in plants with inertial controlled thermonuclear fusion, as well as for short-lived isotopes for nuclear medicine or proton radiotherapy.
In a paper published in journals such as Physical Review E, Physics of Plasmas, Bochkarev and his colleagues described their mathematical models to accelerate the ions and electrons in the interaction of a femtosecond laser pulse with the gas and hyperfine foil.
Experiments have shown that electrons can be accelerated to energies of 1.5 GeV at a distance of only about a centimeter. Beytskovsky electron linear accelerator at the Massachusetts Institute of Technology (USA) accelerates electrons to energies of about 1.1 GeV. However, its length is 160 meters.
According to scientists, modern femtosecond laser systems that are compact enough that they can be mounted on a laboratory bench can be used even for large-scale simulations of cosmic catastrophes, such as gamma-ray bursts.
«Using high power laser systems, today provides an opportunity to create a plasma, whose parameters are close to the parameters of real gamma-ray bursts. The presence of such systems will enable more complex tasks, such as the study of cosmic rays birth mechanism in the universe "- said Sergey Bochkarev, one of the authors.
