TL;DR: In this article, a new high-order harmonic generation mechanism reaching the "water window" spectral region was demonstrated with multiterawatt femtosecond lasers irradiating gas jets.
Journal ArticleDOI
Nondestructive assay of plutonium and minor actinide in spent fuel using nuclear resonance fluorescence with laser Compton scattering γ-rays
Takehito Hayakawa,Nobuhiro Kikuzawa,Ryoichi Hajima,Toshiyuki Shizuma,Nobuyuki Nishimori,Mamoru Fujiwara,Mamoru Fujiwara,Michio Seya +7 more
TL;DR: In this paper, a high-flux Compton scattering (LCS) γ -ray source was proposed to detect 235U, 239Pu, and minor actinides in spent nuclear fuel assembly in a water pool.
Journal ArticleDOI
Detection of radioactive isotopes by using laser Compton scattered γ-ray beams
Ryoichi Hajima,Nobuhiro Kikuzawa,Nobuyuki Nishimori,Takehito Hayakawa,T. Shizuma,K. Kawase,Masaki Kando,Eisuke Minehara,H. Toyokawa,Hideaki Ohgaki +9 more
TL;DR: In this article, the authors used laser Compton scattered (LCS) γ-ray beams and the nuclear resonance fluorescence (NRF) for the non-destructive detection of radioactive materials.
Journal ArticleDOI

TL;DR: In this article, a non-destructive method for detecting the elemental and isotopic composition of materials concealed by heavy shields such as iron plates with a thickness of several centimeters is presented. But the method is limited to the case of a lead block hidden behind 1.5 cm-thick iron plates.
