  The dynamic processes of magnetic reconnection and turbulence cause magnetic
islands/flux-ropes generation. The in-situ observations suggest that the
coalescence or/and contraction of magnetic islands are responsible to the
charged particle acceleration (keV to MeV energy range). Numerical simulations
also support this acceleration mechanism. However, the most fundamental
question raise here is, does this mechanism contribute to the cosmic rays
acceleration? To answer this, we report, in-situ evidence of flux-ropes
formation, their magnetic re-connection and its manifestation as cosmic ray
(GeV charged particle) acceleration in interplanetary counterpart of coronal
mass ejection(ICME). Further, we propose that cosmic ray (high and/or
ultra-high energy) acceleration by Fermi mechanism is valid not only through
stochastic reflections of particles from the shock boundaries but also through
the boundaries of contracting magnetic islands or/and their merging via
magnetic re-connection. This has significant implications on cosmic ray origin
and their acceleration process.
