Spectrum of Solar Cosmic Rays Near the Earth
As it was postulated in Chapter 1, an energy distribution (or a shape of the energy spectrum) of solar cosmic rays (SCR) is of great significance for the formulation of self-consistent model of particle acceleration at the Sun. In turn, the main problems of fundamental interest in the theory of particle acceleration at the Sun lie now at two boundary domains of SCR spectra, namely, in low-energy (non-relativistic) and high-energy (relativistic) ranges. The most important of them are: initial acceleration from the thermal background (see, e.g., Vlahos et al, 1989, Simnett, 1995; Miroshnichenko, 1995; Miller et al., 1997) and final stage of acceleration to extremely high energies (see, e.g., Miroshnichenko, 1994, 1996; Karpov etal, 1995, 1998).
