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.
Of the atomic processes which are important in tokamak plasmas, collisional processes are reviewed : ionization, recombination and excitation of ions by electron impact and charge transfer between ions and hydrogen
In the past few years, the use of RF heating has led to significant improvements in fusion plasma parameters. The launcher which radiates ICRF waves into the plasma is, in especial, the critical component where the physics and technology of ICRH meet. This paper shows the launchers for ICRH and LHH bolted onto a rectangular port opening in the first wall of the tokamak and mode converters for ECH.
An optical cell was constructed for the comparative study of the excitation characteristics of the laser medium between the REB (Relativistic Electron Beam) and the transverse discharge.
