Fast ignition realization experiment with high-contrast kilo-joule peta-watt LFEX laser and strong external magnetic field

Abstract: for an Invited Paper for the DPP15 Meeting of the American Physical SocietyWe report on progresses of the Fast Ignition Realization Experiment (FIREX) project that has been curried out at the Institute of Laser Engineering to assess the feasibility of high density core heating with a high-power, short-pulse laser including the construction of the Kilo-Joule, Petawatt class LFEX laser system. Our recent studies identify three scientific challenges to achieve high heating efficiency in the fast ignition (FI) sch… Show more

“…This ensures coupling of the laser energy to ions and its considerable role in further dynamics. With the advent of short pulse CO 2 lasers and the possibility of magnetic field generation of the order of kilo Tesla have already been demonstrated [21][22][23][24][25][26][27][28], we belive that this class of experiments to be feasible in near future.…”

“…The focal spot diameter of the combined laser beam was 60 µm, it contained 50% of the total laser pulse energy, 710 ± 10 J. The laser pulse length was 1.3 ± 0.5 ps at full-widthat-half-maximum, so the laser intensity on the target was ≈ 9.7× 10 18 W/cm 2 , with the contrast between the main pulse intensity and the nano-second foot pulse better than 10 9 [16].…”

“…However, in general, the propagation and interaction behavior of intense EM waves in magnetized plasmas are rather complex even in the linear limit [1,2], especially when the plasma density and magnetic field are highly inhomogeneous, so that intensive numerical simulation would be required for their investigation. Finally, it may be of interest to point out that kilo-tesla magnetic fields have recently been used for efficiently guiding relativistic electron beams in dense plasma [40].…”
