Times Cited Count:62 Percentile:92.91(Optics)High-intensity laser and thin-foil interactions produce high energy ions, electrons, hard X-ray, and terahertz radiation. The simultaneous generation of the protons and terahertz radiation will provide us unique applications. In this study we use a Ti:sapphire laser system (JLITE-X) at JAEA for simultaneous generation of the protons and terahertz radiation. The laser beam is focused by an off-axis parabolic mirror at the Ti target surface. The estimated peak intensity is 210W/cm. The simultaneous generation of the protons and terahertz radiation are observed by reducing the ASE duration.

Times Cited Count:18 Percentile:40.59(Environmental Sciences)In a sediment core of Nishiyama reservoir at Nagasaki, depth profiles of Pu/Pu ratio, Pu and Cs concentrations were determined. Sediments containing plutonium and Cs, which were fallout deposited immediately after a detonation of Nagasaki atomic bomb, were identified in the core. Observed below the sediments were macroscopic charcoals, providing evidence for initial deposit of the fallout. This is the first entire depositional records of plutonium and Cs released from the Nagasaki atomic bomb together with those from atmospheric nuclear tests.
