Description
I will review the current status of our understanding of the physical processes involved
in the acceleration of cosmic rays (CRs), with special attention for supernova remnants
as the main candidate sources for the bulk of CRs. Recent multifrequency observations,
especially in the gamma ray band, have shed new light and raised new shadows on the
general framework of the origin of CRs in the Galaxy and I will discuss the new
directions in which these trends are pushing our investigations, with particular
emphasis on magnetic field amplification and waves in partially neutral plasmas which
appear to play a crucial role to explain observations.
