A team of scientists from Imperial College London has theoretically substantiated a new method that allows some materials to be heated to temperatures higher than the core of the Sun. Moreover, the process will take a tiny period of time - 1/20 of a quadrillion second. These results are hundreds of times higher than those obtained by their colleagues at the US Livermore National Laboratory.
Gaining access to unlimited energy is rightfully considered the Holy Grail of modern nuclear physics. True, for this it is necessary to recreate processes similar to those taking place in the core of the Sun. British physicists have concluded that lasers are best suited for this purpose.
Moreover, the Imperial College team suggested not just heating the material, but doing it according to a certain "scheme". Under normal conditions, the laser heats the electrons, which in turn heats the ions, which basically make up the mass of the object. Unfortunately, this is very slow.
British physicists decided to “cut out” electrons from this process so that the ions could be heated “directly”. In the course of the experiments, scientists found out that some substances generate a shock wave under the influence of high-intensity lasers.
With the help of computer simulation, it was possible to establish that materials with increased density (plastic, cesium hydride) have a special arrangement of ions. When they are accelerated, compression occurs and the resulting electrostatic wave intensifies the effect of friction between ions by tens of times, which leads to heating of the material.
If it is possible to implement the obtained results in practice, it will be possible to heat a small amount of a substance to 11.6 million ° C in tens of femtoseconds. This will be a significant advance in the study of thermonuclear processes.
