| Abstract: | Plasma current induced by a strong dc electric field is studied by Fokker-Planck (FP) simulation. Based upon this, a hydrodynamic-like equation, similar to Spitzer's but without the weak-field limit, is given for calculating the current. This equation is suitable for application in hybrid-PIC simulations relevant to the fast ignition (FI) scheme. Furthermore inverse bremsstrahlung (IB) absorption is studied in a wide laser intensity range. In particular, we introduce an IB operator which is similar to Langdon's, but without the low laser intensity limit. This operator enables one to treat IB absorption properly in the inertial confinement fusion (ICF) schemes with the NIF/LMJ-scale laser intensity beyond 10¹⁵ W/cm². |
