X-ray pumping of the Th-229 nuclear clock isomer
Takahiko Masuda, Akihiro Yoshimi, Akira Fujieda +27
Thorium-229 is a unique case in nuclear physics: it presents a metastable first excited state Th-229m, just a few electronvolts above the nuclear ground state. This so-called isome…
Energy response of X-rays under high flux conditions using a thin APD for the energy range of 6-33 keV
T. Masuda, T. Hiraki, H. Kaino +10
This paper reports on the demonstration of a high-rate energy measurement technique using a thin depletion layer silicon avalanche photodiode (Si-APD). A dedicated amplitude-to-tim…
Nuclear resonant scattering experiment with fast time response: new scheme for observation of Th radiative decay
A. Yoshimi, H. Hara, T. Hiraki +24
Nuclear resonant excitation of the 29.19-keV level in Th with high-brilliance synchrotron- radiation and detection of its decay signal, are proposed with the aim of populat…
Fast X-ray detector system with simultaneous measurement of timing and energy for a single photon
T. Masuda, S. Okubo, H. Hara +12
We developed a fast X-ray detector system for nuclear resonant scattering (NRS) experiments. Our system employs silicon avalanche photo-diode (Si-APD) as a fast X-ray sensor. The s…
