  Recently a new high energy proton microscopy facility PRIOR (Proton
Microscope for FAIR) has been designed, constructed and successfully
commissioned at GSI Helmholtzzentrum f\"ur Schwerionenforschung (Darmstadt,
Germany). As a result of the experiments with 3.5-4.5 GeV proton beams
delivered by the heavy ion synchrotron SIS-18 of GSI, 30 um spatial and 10 ns
temporal resolutions of the proton microscope have been demostrated. A new
pulsed power setup for studying properties of matter under extremes has been
developed for the dynamic commissioning of the PRIOR facility. This paper
describes the PRIOR setup as well as the results of the first static and
dynamic proton radiography experiments performed at GSI.
