Stopping power and transport of multi-KeV electrons into pre-compreesed target

Summary form only given. The idea to separate compression and ignition phase of Inertial Confinement Fusion (ICF) was proposed to reduce hydrodynamic instability as well as improving target performance. In this context Fast and Shock ignition have been developed widely. Shock ignition (SI) is one of the newest approaches used in ICF, which has the potential of achieving high gain. Generation of fast electrons during the ignition phase of SI and their transport are important issue in SI context.In this work, using Monte-Carlo model, stopping power of the most energetic electrons generated through high intensity laser-plasma interaction and their transport into precompressed fuel are considered. Initial condition of the precompressed fuel such as density profile, is obtained by MULTI [1], a hydrodynamic radiation code. Afterward, range and energy loss of fast electrons are computed with Monte-Carlo simulations. HiPER baseline target and pulse are applied. Accurate results based on electron-electron and electron-ion cross section [2] and continuous slowing down of electrons are obtained. It has shown that depending on initial condition, hot electrons transport and their energy deposition into pre-compressed target have significant effect on target performance.
