Enhancement of J x B electron acceleration with the micro-structured target and picosecond high-contrast relativistic-intensity laser pulse
Ryunosuke Takizawa, Yuga Karaki, Hiroki Matsubara +8
Efficient generation of multi-hundred-keV electrons is essential for isochoric heating and can influence ion acceleration. We investigated electron acceleration from copper-oleate…
Enhanced plasma heating via interaction with high-contrast laser and cone-shaped target
Yuga Karaki, Yoshitaka Mori, Eigo Ebisawa +25
We investigated plasma heating enhancement using a high-intensity, high-contrast laser and a cone-attached target. Fast electron spectra and X-ray emission were measured with an el…
Peta-Pascal Pressure Driven by Fast Isochoric Heating with Multi-Picosecond Intense Laser Pulse
Kazuki Matsuo, Naoki Higashi, Natsumi Iwata +31
Fast isochoric laser heating is a scheme to heat a matter with relativistic-intensity ( 10 W/cm) laser pulse or X-ray free electron laser pulse. The fast isochoric la…
Super-ponderomotive electron acceleration in blowout plasma heated by multi-picosecond relativistic intensity laser pulse
Sadaoki Kojima, Masayasu Hata, Natsumi Iwata +25
The dependence of the mean kinetic energy of laser-accelerated electrons on the laser intensity, so-called ponderomotive scaling, was derived theoretically with consideration of th…
Magnetized Fast Isochoric Laser Heating for Efficient Creation of Ultra-High-Energy-Density States
Shohei Sakata, Seungho Lee, Tomoyuki Johzaki +36
The quest for the inertial confinement fusion (ICF) ignition is a grand challenge, as exemplified by extraordinary large laser facilities. Fast isochoric heating of a pre-compresse…
Kinetic modeling of x-ray laser-driven solid Al plasmas via particle-in-cell simulation
Ryan Royle, Yasuhiko Sentoku, Roberto C. Mancini +2
Solid-density plasmas driven by intense x-ray free-electron laser (XFEL) radiation are seeded by sources of non-thermal photoelectrons and Auger electrons that ionize and heat the…
Laser-ion acceleration via anomalous electron heating
A. Yogo, K. Mima, N. Iwata +23
Using a kilojoule class laser, we demonstrate for the first time that high-contrast picosecond pulses are advantageous for ion acceleration. We show that a laser pulse with optimum…
Integrated simulation of magnetic-field-assist fast ignition laser fusion
T. Johzaki, H. Nagatomo, A. Sunahara +13
To enhance the core heating efficiency in fast ignition laser fusion, the concept of relativistic electron beam guiding by external magnetic fields was evaluated by integrated simu…
Theory of Fast Electron Transport for Fast Ignition
A. P. L. Robinson, D. J. Strozzi, J. R. Davies +6
Fast Ignition Inertial Confinement Fusion is a variant of inertial fusion in which DT fuel is first compressed to high density and then ignited by a relativistic electron beam gene…
Integrated Fast Ignition Simulation of Cone-guided Targetwith Three Codes
Hitoshi Sakagami, Tomoyuki Johzaki, Hideo Nagatomo +1
It was reported that the fuel core was heated up to ~ 0.8 [keV] in the fast ignition experimentswith cone-guided targets, but they could not theoretically explain heating mechanism…
