Abstract :
The paper discusses devices with a Disk Explosive Magnetic flux compression Generator (DEMG), which are similar to the ALT-1,2 experimental devices and are intended for testing the possibility of producing 1-3 TPa (10-30 Mbar) pressures and the possibility of measuring Hugoniots of different materials at such pressures. It is expected that two-layer, cylindrical liners, Al+Fe and/or Al+W, will be used, driven by 4-5 MG magnetic fields to ~ 20 km/s velocities. The paper presents and discusses simulated characteristics of these devices, in which currents, energies and powers delivered to the liner load can reach ~ 70 MA, ~ 40 MJ and ~ 20 TW and exceed those in the ALT-1,2 devices by a factor of ~2, ~ 4 and ~ 7, respectively.
