“…For example, Pre‐compressed fuel plasmas in the fast ignition approach, mainly have a density and temperature range of 100–1000 gcm −3 and 0.1–1 keV, respectively. [ 16,28,29 ] So, MLP theory is widely applicable in ICF plasma's due to its simplicity both in concept and computation. The MLP stopping power of a test charged particle (with subscript t) with mass m t , charge Z t e , and velocity v t which moves through hot field plasma (with subscript f ) with mass m f , charge Z f e , and velocity v f is presented by:

“…It forms a condensed matter state, named “clusters”, in the converter material lattice defects. [ 16 ] This novel cluster‐based converter foil could increase the performance of converter foil with a more loading of the deuterium in the bulk of the foil. Although, further studies are needed to increase the packing fraction of clusters in the host material and thereby secure sufficient deuteron flux in FI.…”

The laser‐generated deuteron beam is a promising scheme for providing the required energy for igniting a pre‐compressed fuel in the fast ignition method in the inertial confinement fusion approach. Deuteron beam provides extra energy through beam‐fusion(BF) reactions during the hot‐spot formation in the pre‐compressed fuel. During the compression and hot‐spot formation stages, Impurities are produced due to the mixing of the fuel with the material of the structural elements of the target. So, the efficiency of BF of the deuteron beam in a spherical deuteron‐triton(DT) fuel in the presence of impurity (such as beryllium, carbon, aluminium, and gold) with arbitrary concentration is investigated. Deuteron beam was considered with Maxwellian energy distribution at a temperature of 3 MeV, which passes through the pre‐compressed contaminated DT fuel with a non‐uniform density profile. It shows that an increase of mixed‐ion charge state and density ratio results in the substantial diminution of the deuteron BF probability, which leads to a reduction in deuteron's extra bonus energy. The effect of fuel temperature on the BF probability in contaminated DT fuel is discussed. Calculations show that increasing the temperature enhanced BF probability.

The hot spot heating process by an assumed deuteron beam is evaluated in order to estimate the contribution of the energy produced by the deuteron beam-target fusion to the heating process. The deuteron beam energy versus the number of deuterons is evaluated through the experimentally achieved proton beam energy distribution using the TRIDENT short pulse laser at the Los Alamos National Laboratory (LANL). The corresponding hot spot heating is then calculated using this assumed deuteron beam spectrum. The resulting first order heating dynamics is employed in the expanded “bonus” energy calculation, and a 12.73% extra energy from deuteron beam-target fusion was found with the assumed deuteron spectrum when ρrb = 4.5 g/cm2 is considered, where ρ is the fuel density, and rb is the ion beam focusing radius on the target. The results provide further insight into the contribution of the extra heat produced by deuteron beam-target fusion to the hot spot ignition process. A further analysis of how a converter foil using ultra-high-density cluster materials can help to achieve the yield requirements for ignition is presented.
