Abstract Recently, a new technique (pRad) has been developed, which uses high
energy protons for flash radiography. PRad allows much more detailed information
to be obtained from dynamic experiments than was ever available in the past. 
Since the first demonstration of the focusing of protons for radiography in 1995,
huge progress has been made in developing techniques for fast imaging ofdynamic
experiments that have made proton radiography an important contributor to the
study of shock driven physics.  Movies of up to 33 frames can be made of
explosively driven experiments, allowing new phenomena to be observed and
quantified. New capabilities are being added to the facility continuously.
The technique will be described, results from recent experiments will be 
presented and other applications of charged particle radiography will be 
descried.
