An accelerated micro-foil is used to ignite a pre-compressed cylindrical shell containing deuterium-tritium fuel. The well-known shock wave ignition criterion and a novel criterion based on heat wave ignition are developed in this work. It is shown that for heat ignition very high impact velocities are required. It is suggested that a multi-petawatt laser can accelerate a micro-foil to relativistic velocities in a very short time duration (˜picosecond) of the laser pulse. The cylindrical geometry suggested here for the fast ignition approach has the advantage of geometrically separating the nanosecond lasers that compress the target from the picosecond laser that accelerates the foil. The present model suggests that nuclear fusion by micro-foil impact ignition could be attained with currently existing technology.

Abstract. We improved diagnostic instruments to measure X-ray images in a hard X-ray harsh environment and succeeded in obtaining clear images with X-ray framing camera and X-ray streak camera in fast ignition experiment conducted in 2011 (FG-02 Experimental Campaign). We found that high-energy X-ray signals could be used as an indicator of the LFEX laser injection time relative to the imploded core. The LFEX laser injection time was estimated with better than 10 ps accuracy. Time-resolved 2D X-ray images suggested that shapes and motions of imploded core plasmas were improved by changing the configuration of the implosion lasers.

“…( R) min ≈ 0.18 g/cm 2 at T ig ≈ 7 keV in the case of an isobaric plasma ( = 0); ( R) min ≈ 0.32 g/cm 2 at T ig ≈ 10 keV in the case of isochoric plasma ( = 0.87) and ( R) min ≈ 0.48 g/cm 2 at T ig ≈ 12 keV in the case of a homogeneous plasma ( = 2). At 10 % impurity, ( R) min increases by about 1.5 times in the case of a beryllium impurity and by about 2 times in the case of carbon impurity for all plasma configurations.…”

“…Meaning the both problems the ignition and combustion of DT-plasma containing the impurities of carbon ( 6 C 12 ), beryllium ( 4 Be 9 ) and lithium ( 3 Li 7 ) are investigated. The ignition criterion, ignition energy and gain are defined at arbitrary concentration of impurities for homogeneous plasma, as well as isobaric plasma formed at the conventional spark ignition of ICF-target, including shock ignition [1] and isochoric plasma formed at fast ignition [2]. This paper is the summary of a conference presentation preceding the publication of paper [3], where a number of the results can be found in more detail.…”

Abstract. The ignition criterion, ignition energy and gain of DT-plasma of ICF-target in the presence of impurities of light atoms such as beryllium, carbon and lithium at their arbitrary concentration are found. It is shown that the most promising type of non-cryogenic solid thermonuclear fuel is DT-hydride of beryllium (BeDT). It is suggested to apply the targets with such a fuel as: (1) Fast-ignited ICF-target at the ignition energy of 25-50 kJ and compression driver energy of 2-3 MJ; (2) ICF-target spark-ignited by 15-20 MJ heavy ion driver; (3) Spark-ignited target by 5-7 MJ laser as a neutron source for hybrid fusion-fission.
