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…

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…
