Inertial Confinement Fusion by particle beams

The physical and technical issues in Inertial Confinement Fusion (ICF) by particle beams are reviewed comparing the required parameters with the present state of art. They are pulse power technology, diode technology for generation of highly bright beam and its focusing, transport of beams without loss of focusability, and target interaction and implosion. Power concentration is the principal concern for proof-of-principle of beam ICF.
