Probing In-Solid Proton Energy Distributions in Laser-Driven Fusion via Nuclear Activation Diagnostics
Hiroki Matsubara, Ryunosuke Takizawa, Yuga Karaki +25
The energy distribution of energetic protons inside a solid target is a key quantity governing nuclear reaction yields and energy deposition in high-intensity laser-driven fusion,…
Time-Resolved Interferometric Measurements of Plasma Density Evolution in Laser-Driven Capacitor-Coil Targets
Yang Zhang, Ryo Omura, Rinya Akematsu +17
Laser-driven capacitor-coil targets provide a compact platform for generating strong magnetic fields and are widely used in magnetized high-energy-density plasma experiments. In ad…
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…
