| Outline of Final Research Achievements |
An irradiating substance with an intense laser pulse produces laser plasma with high energy density. This plasma attracts significant attention due to its applications on such as high-energy particle acceleration, ultrashort pulse radiations, and high-speed ignition fusion. These laser plasma-mediated phenomena occur from electron motion, which is accelerated by a strong electromagnetic field instantly created by the intense laser pulse. Therefore, it is important to investigate the behavior of these electrons with high temporal and spatial resolution. The purpose of this research is to demonstrate time-resolved radiograph measurement for observing an ultrafast transient electromagnetic field created by electron motion and changing on a time scale of 100 fs.
