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…
Dynamics of ultrafast heated radiative plasmas driven by petawatt laser lights
K. Sugimoto, N. Iwata, A. Sunahara +2
A relativistic petawatt laser light can heat heavy metals over keV temperature isochorically and ionize them almost fully. Copious hard X-rays are emitted from the high-Z hot plasm…
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…
Broadening of Cyclotron Resonance Conditions in the Relativistic Interaction of an Intense Laser with Overdense Plasmas
Takayoshi Sano, Yuki Tanaka, Natsumi Iwata +4
The interaction of dense plasmas with an intense laser under a strong external magnetic field has been investigated. When the cyclotron frequency for the ambient magnetic field is…
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…
