Description
We reconstruct an ultimate spectrum of solar/stellar cosmic rays (SCR) in a given point in the
heliosphere (stellar sphere) basing on maximal value of magnetic field strenght in active region and its characteristic
linear dimension. An accelerator of given dimensions and magnetic field strengh may accelarate to a finite energy for
a given time (a maximal energy of SCR). We will use spectrum of SCR proposed by Syrovatsky (1961) for relativistic
and non-relativistic energies normaliszing it to galactic cosmic ray (GCR) intensity at maximal SCR energy. Maximal
values of SCR flux propagating in the heliosphere are determined by equilibrium between pressure of interplanetary
magnrtic field and dynamic pressure of SCR (Frier&Webber, 1963). The obtained spectra would be applied to explain
the extreme solar particle event occurred in about 775 AD basing on the tree-ring chronology (Miyake et al., 2012).
