Abstract The solid state fuel ignition was given by Chu and Bobin according to the hydrodynamic theory at x=0 qualitatively. A high threshold energy flux density, i.e., E*=4.3×1012 J/m2, has been reached. Recently, fast ignition by employing clean petawatt-picosecond laser pulses was performed. The anomalous phenomena were observed to be based on suppression of prepulses. The accelerated plasma block was used to ignite deuterium-tritium fuel at solid state density. The detailed analysis of the thermonuclear wave propagation was investigated. Also the fusion conditions at x≠0 layers were clarified by exactly solving hydrodynamic equations for plasma block ignition. In this paper, the applied physical mechanisms are determined for, such as, nonlinear force laser driven plasma blocks, thermonuclear reaction, heat transfer, electron-ion equilibration, stopping power of alpha particles, bremsstrahlung, expansion, density dependence, and fluid dynamics. New ignition conditions may be obtained by using temperature equations, including the density profile that is obtained by continuity equation and expansion velocity. The density is only a function of x and independent of time. The ignition energy flux density, Et*, for the x≠0 layers is 1.95×1012 J/m2. Thus threshold ignition energy in comparison with that at x=0 layers would be reduced to less than 50 percent.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
