Abstract
Ignition conditions in axially magnetized cylindrical targets are investiga ted by examining the thermal balance of assembled DT fuel configurations at stagnation. Special care is taken to adequately evaluate the energy fracti on of 3.5 MeV alpha particles deposited in magnetized DT cylinders. A detai led analysis of the ignition boundaries in the rho R, T parametric plane is presented. It is shown that the fuel magnetization allows a significant re duction of the rho R ignition threshold only when the condition BR greater than or similar to 6 x 10(5) G cm is fulfilled (B is the magnetic field str ength and R is the fuel radius).
