Outline of Final Research Achievements |
In the fast ignition scheme using cone-guided targets for the laser fusion, the divergence angle of generated fast electrons is too large and their slope temperature is too high. Thus it results in lower heating efficiency from fast electrons to the compressed fuel core. To mitigate this critical issue, energetic ions which are also generated by the heating laser are expected to additionally heat the fuel core. On the other hand, using a shorter wavelength but same intensity laser can reduce the slope temperature of fast electrons without decreasing laser energy, and it is expected to enhance the core heating. Finally, externally-applied longitudinal magnetic fields is expected to guide fast electrons to the core. So the core heating properties are estimated by integrated simulations for each idea, and conditions for better heating are obtained.
