Disk EMG System for Driving Impacting Liners to20 km/s.

摘要

We consider an ALT-1,2-like system to deliver up to 60-70 MA currents in the liner load and accelerate approximately 20 g/cm cylindrical liners to approximately 20 km/s (ALT-1,2:31 MA,13 g/cm,12 km/s). The system is intended for the ALT- 3 experiment to test the efficiency of magnetic implosion of impacting liners and to verify the possibility of shock-wave measurements at up to 1 TPa pressures. We describe the physical configuration of the system and its diagnostic suite, which differ significantly from similar systems. As compared with, changes are made to the physical configuration of individual system units and a number of system parameters: we increase load inductance by a factor of 1.5, use a different transmission line and an Al liner (instead of envisaged two-layer liners) etc. Simulated characteristics of the system are presented.
