Summary on Grant Application Form |
A sophisticated model of flaring atmosphere heated by a neutralised beam (protons and electrons) with energy power law spectrum injected from the primary energy release site on the top is investigated. Protons and electrons of the neutralised beam are assumed to precipitate into a converging magnetic loop down to the bottom of the atmosphere in Coulomb and inelastic collisions with the ambient plasma and beam ions and electrons while protons also exchange their energy with the ambient plasma electrons via the kinetic Alfven wave turbulence. A possible separation of electrons from protons in the beam during the precipitation caused by a wide-angular electron scattering is to be taken into account by solving the kinetic and integral Ohmic law equations. Further precipitation of both beams to the bottom of the atmosphere is also investigated as well as their energy deposition at given depth and its timescale, the outcome is to be compared with helioseismic observations. A temporal evolution of the resulting hard X-ray bremsstrahlung and soft X-ray line emission (Ca XIX, Si XV, Fe XXV) from flaring atmospheres is to be compared with those produced by pure electron beams and the observed ones.
