Investigation Of Liner Ponderomotor Units, Used As Drivers In Magnetic Implosion System

A system design for investigation of the feasibility of controlled inertial thermonuclear fusion (ITF), based on target implosion by fast-rising magnetic field was published in 1979. The base of this design became the realization of a powerful explosive-magnetic generator (EMG) of disc type by that time. Only the disc EMG capable to be employed as a current source for energy releasing unit - a ponderomotor unit (PU), in which the magnetic field energy is converted into a kinetic one of axial symmetric shells-liners, imploding and heating a thermonuclear target. A principle scheme of PU with two cylindrical implosion liners is considered in the report. The experimental results with the energetic liner, having initial surface mass m=4.3-10/sup -2/ g/cm/sup 2/and aspect ratio of 10/sup 3/ , accelerated to 25 km/s and with the main liner of 30 mm in diameter (Do) and m=1.06*10/sup -3/g/cm /sup 2/, accelerated to 50 km/s are presented in this report. The problem of the implosion liner compression symmetry is considered. Data on the motion symmetry of heavy nonexploding liners, gaining energy up to 25 MJ during acceleration are available.
