Positron generation and acceleration in a self-organized photon collider enabled by an ultra-intense laser pulse
K. Sugimoto, Y. He, N. Iwata +4
We discovered a simple regime where a near-critical plasma irradiated by a laser of experimentally available intensity can self-organize to produce positrons and accelerate them to…
Conditions of structural transition for collisionless electrostatic shock
Minh Nhat Ly, Takayoshi Sano, Youichi Sakawa +1
Collisionless shock acceleration, which transfers localized particle energies to non-thermal energetic particles via electromagnetic potential, is ubiquitous in space plasma. We in…
Optimizing laser coupling, matter heating, and particle acceleration from solids using multiplexed ultraintense lasers
Weipeng Yao, Motoaki Nakatsutsumi, Sébastien Buffechoux +20
Realizing the full potential of ultrahigh-intensity lasers for particle and radiation generation will require multi-beam arrangements due to technology limitations. Here, we invest…
Nanoscale subsurface dynamics of solids upon high-intensity laser irradiation observed by femtosecond grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Thomas R. Preston +28
Observing ultrafast laser-induced structural changes in nanoscale systems is essential for understanding the dynamics of intense light-matter interactions. For laser intensities on…
Plasma Concept for Generating Circularly Polarized Electromagnetic Waves with Relativistic Amplitude
Takayoshi Sano, Yusuke Tatsumi, Masayasu Hata +1
Propagation features of circularly polarized (CP) electromagnetic waves in magnetized plasmas are determined by the plasma density and the magnetic field strength. This property ca…
Thermonuclear Fusion Triggered by Collapsing Standing Whistler Waves in Magnetized Overdense Plasmas
Takayoshi Sano, Shinsuke Fujioka, Yoshitaka Mori +2
Thermal fusion plasmas initiated by standing whistler waves are investigated numerically by two- and one-dimensional Particle-in-Cell simulations. When a standing whistler wave col…
