Fast Ignitor Concept with Light Ions

چکیده
A short-laser-pulse driven ion flux is examined as a fast ignitor candidate for inertial confinement fusion. Ion ranges in a hot precompressed fuel are studied. The ion energy and the corresponding intensity of a short laser pulse are estimated for the optimum ion range and ion energy density flux. It is shown that a lightion beam triggered by a few-hundreds-kJ laser at intensities of ~10 21 W/cm 2 is relevant to the fast ignitor scenario. © 2001 MAIK “Nauka/Interperiodica”.

This paper deals with the role of fast ignitor in fast-shock ignition (FSI) concept. The semi-analytical model indicates that the FSI target gain is a function of fast ignitor laser wavelength. If the energy of fast ignitor driver is and the laser wavelength is less than 0.53 micron, then with a fuel mass about 2 mg the FSI has a considerable advantage over pure shock ignition and the figure o...
متن کاملافروزش سریع- شوکی رهیافتی نوین برای همجوشی محصور سازی اینرسی
A new concept for inertial confinement fusion called fast-shock ignition (FSI) is introduced as a credible scheme in order to obtain high target gain. In the proposed model, the separation of fuel ignition into two successive steps, under the suitable conditions, reduces required ignitor energy for the fuel ignition. The main procedure in FSI concept is compressing the fuel up to stagnation. T...
متن کاملProgress on the Development of Ion Based Fast Ignition
Results from research on fusion fast ignition (FI) initiated by laser-driven ion beams is encouraging so far. FI based on a beam of quasi-monoenergetic ions (protons or heavier ions) has the advantage of a more localized energy deposition, which minimizes the required total beam energy, bringing it close to the theoretical minimum of ≈ 10 kJ. High-current, laser-driven ion beams are excellent f...
متن کاملLaser Induced Nuclear Physics and Applications
Laser induced beams of protons, neutrons and gamma rays using short pulse lasers is currently important principally because of the potential applications e.g. isotope production, transmutation studies, laser induced fission, heavy ion fusion reactions, neutron production and radiography, fast ignitor and spallation studies of neutrons. Although the Strathclyde group in collaboration with teams ...
