AB  - Fast ignition (FI) is investigated via integrated particle-in-cell simulation including both generation andtransport of fast electrons, where petawatt ignition lasers of 2 ps and compressed targets of a peak density of300 g cm−3 and areal density of 0.49 g cm−2 at the core are taken. When a 20 MG static magnetic field isimposed across a conventional cone-free target, the energy coupling from the laser to the core is enhancedby sevenfold and reaches 14%. This value even exceeds that obtained using a cone-inserted target,suggesting that the magnetically assisted scheme may be a viable alternative for FI. With this scheme, it isdemonstrated that two counterpropagating, 6 ps, 6 kJ lasers along the magnetic field transfer 12% of theirenergy to the core, which is then heated to 3 keV.
