Abstract :
Magnetized target fusion (MTF) is a pulsed approach that compresses magnetized fuel to achieving burning hydrogen plasma conditions. The compression in one MTF-scenario comes from uses a conducting liner that is imploded due to the action of high electrical currents that flow on the outer surface of the liner. This implosion compresses and heats a dense, warm magnetized deuterium or deuterium-tritium plasma. In the present work, MHD numerical simulations of a representative MTF configuration are used to study the effect of radiative losses on the compressional heating rate and the stability of the liner/plasma system late in time. SESAME equations of state and conductivity tables are used for all materials.
