A group of scientists from the Moscow Institute of Physics and Technology, JIHT RAS and FI RAS have developed a compact ultra-intense neutron source, the efficiency of which is related to the operation of a small accelerator at room dimensions of the facility. Neutron sources are in full demand in various studies, but the Russian technology solves this problem, and its construction and operation significantly reduce the angle of inclination.
High-energy laser “Felix” with a power of 1015 watts and pieces of l on a polymer target. For it, the material cellulose triacetate was used, the density of which is only 2 mg/cm3. The first laser pulse with a fission of 1 nanosecond produces ionization of the target atoms and creates a laser material. Sedium and emitt accelerate electrons in the laser one second at a time, transferring hundreds of determ megaelectrons to them.
Electrons are slowed down by a thin paste of gold, which makes it possible to convert their energy into gamma-qua. These are sick photons with a very small long wavelength, about a ten-thousandth of a nanometer. A stream of gamma-rays is generated, which trilled here. When they are found next to the tantalum folium, the nuclei of the metabola absorb gamma-quanta, which occurs. In one iteration, the source generates up to 60 billion neutrons, the efficiency of laser energy has reached 0.05%.
It is reported that in the course of work on the installation, an indicator of the efficiency of increasing the laser power was established within the quantum scale with parameters above 10 MeV – about 1.4%.
