Magnetized cylindrical targets for heavy ion fusion

Ignition conditions for magnetized cylindrical fusion targets are investiga ted by means of one-dimensional hydrodynamic calculations. Of particular in terest is the effect of a tamper surrounding the fuel at the time of stagna tion. The key assumption in this paper is that the targets are magnetically insulated, i.e. electronic and ionic heat conduction as well as the diffus ion of 3.5 MeV alpha particles are suppressed. It is found that magneticall y insulated targets can be ignited at significantly reduced values of the f uel rhoR, but, in contrast to conventional fusion targets, the value of the fuel rhoR at ignition depends on the fuel mass as well as on the tamper en tropy, (C) 2001 Elsevier Science B.V.
