Polarized quantum effects in countable signals from intense laser - electron beam interactions
Toseo Moritaka, Kensuke Homma, Kazunori Itakura
We investigate the feasibility of precision counting experiments based on laser-electron beam interactions to verify strong-field quantum electrodynamic effects, with particular em…
Competition of magnetic reconnections in self-generated and external magnetic fields
K. Sakai, T. Y. Huang, N. Khasanah +13
We investigate the competition of magnetic reconnections in self-generated and external magnetic fields in laser-produced plasmas. The temporal evolution of plasma structures measu…
Mushroom-instability-driven Magnetic Reconnections in Collisionless Relativistic Jets
Tomohisa Kawashima, Seiji Ishiguro, Toseo Moritaka +2
We study the kinetic plasma dynamics in collisionless relativistic jets with velocity shear, by carrying out particle-in-cell simulations in the transverse plane of a jet. It is di…
High-power laser experiment forming a supercritical collisionless shock in a magnetized uniform plasma at rest
Ryo Yamazaki, S. Matsukiyo, T. Morita +51
We present a new experimental method to generate quasi-perpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and we…
Verification of the global gyrokinetic stellarator code XGC-S for linear ion temperature gradient driven modes
Michael D. J. Cole, Robert Hager, Toseo Moritaka +5
XGC (X-point Gyrokinetic Code) is a whole-volume, total-f gyrokinetic particle-in-cell code developed for modelling tokamaks. In recent work, XGC has been extended to model more ge…
The optimum conditions of laser field depletion in laser-electron beam collision
J. F. Ong, T. Moritaka, H. Takabe
The laser field depletion in laser-electron beam collision is generally small. However, a properly chosen parameter of the laser and electron, the laser field depletion can be opti…
The Suppression of Radiation Reaction and Laser Field Depletion in Laser-Electron beam interaction
J. F. Ong, T. Moritaka, H. Takabe
The effects of radiation reaction (RR) have been studied extensively by using the ultraintense laser interacts with the counter-propagating relativistic electron. At the laser inte…
