3On June 30th, 2021, Academician Alexander Mikhaylovich Sergeev, President of the Russian Academy of Sciences, delivered a scientific presentation at the Joint Institute for Nuclear Research in Dubna.
Superheavy elements are considered today as a tool for obtaining particles from the vacuum, literally from the void. Physical theories posit that a strong electric field in vacuum can produce a particle pair – an electron and a positron, that is, a particle and an antiparticle. So far, no one has been able to produce an electron-positron pair in vacuum using an electric field. Yet, scientists are by no means sitting idle. One experimental way to achieve this is to use the NICA collider that is now under construction in Dubna, scheduled to start up in 2023.
The second version of the birth of an electron-positron pair from vacuum was explained by Alexander Sergeev, the President of RAS, in a research report delivered at an international conference in Dubna: a strong electric field can be created using a powerful laser. “State-of-the art ultra-powerful laser complexes can become an alternative delivering a new compact technology of particle acceleration, generation of coherent X-rays and gamma rays.” Researchers at the RAS Institute of Applied Physics proposed a model of the development of cascades in a rotating electric field, describing distribution functions for particles and large-energy photons. By controlling coupling parameters, it is possible to create directed high-intensity gamma radiation.
