  Shell-type Supernova remnants (SNRs) have long been known to harbour a
population of ultra-relativistic particles, accelerated in the Supernova shock
wave by the mechanism of diffusive shock acceleration. Experimental evidence
for the existence of electrons up to energies of ~100 TeV was first provided by
the detection of hard X-ray synchrotron emission as e.g. in the shell of the
young SNR SN1006. Furthermore using theoretical arguments shell-type Supernova
remnants have long been considered as the main accelerator of protons - Cosmic
rays - in the Galaxy; definite proof of this process is however still missing.
Pulsar Wind Nebulae (PWN) - diffuse structures surrounding young pulsars - are
another class of objects known to be a site of particle acceleration in the
Galaxy, again through the detection of hard synchrotron X-rays such as in the
Crab Nebula. Gamma-rays above 100 MeV provide a direct access to acceleration
processes. The GLAST Large Area telescope (LAT) will be operating in the energy
range between 30 MeV and 300 GeV and will provide excellent sensitivity,
angular and energy resolution in a previously rather poorly explored energy
band. We will describe prospects for the investigation of these Galactic
particle accelerators with GLAST.
