Techniques of integral experiment and methods for validation of evaluated nuclear data libraries for secondary gamma-ray data under D-T neutron field

In order to verify secondary gamma-ray data in evaluated nuclear data libraries, several experimental and analytical methods were proposed. Techniques of in-situ gamma-ray spectrum measurement for fusion neutronics experiments have been established by using a special scintillation detector and pulsed neutrons. An analytical method which can assist identification of error sources in data libraries is attempted. Another method is also proposed to experimentally examine energy valance of secondary gamma-ray data. (author)
