A new concept of a coaxial plasma dynamic accelerator with a self-energized mag-netic compressor coil to simulate the effects of space debris impact is demonstrated.A briefdescription is presented about the pulse power supply system including the charging circuit,startswitch and current transfer system along with some of the key techniques for this kind of acceler-ator.Using this accelerator configuration,ceramic beads of 100 #m in diameter were acceleratedto a speed as high as 18 km/sec.The facility can be used in a laboratory setting to study impactphenomena on solar array materials,potential structural materials for use in space.
