| Popis: | We consider coronal proton acceleration by a spectrum of magnetohydrodynamic (MHD) waves in the geometry of a magnetic loop including wave-wave interactions. The dominant wave-wave interaction is scattering on the polarization clouds of ions, which leads to the transformation of Alfven waves among themselves and with fast magnetosonic waves, and the transformation of fast magnetosonic waves among themselves. These processes have a very small direct effect on the acceleration process because the frequency changes are small |
