Laser-driven particle accelerators are emerging as a promising approach offering extremely high-gradient accelerating fields resulting in compact sources of high-energy electrons and ions characterized by ultra-short bunches duration, high peak current and high brightness[1,2]. Electrons are accelerated exploiting plasma wakefield acceleration that allowed to achieve multi-GeV beams...
Over almost the past six decades, a fleet of space missions, strategically placed throughout the heliosphere at critical vantage points, have been devoted to the exploration of the interplanetary space, greatly advancing our knowledge of how the Sun influences the whole solar system, through the solar wind, a continuous flow of charged particles emitted by the outer layer of the solar...
Ionospheric equatorial plasma bubbles/depletions are plasma density irregularities, which tend to develop under specific conditions during post-sunset hours and continue to evolve non-linearly into the post-midnight period. The Rayleigh–Taylor (Kruskal-Shafranov) instability mechanism is believed to be responsible for the formation of these depletions. An intriguing feature of equatorial...
