Control of emission interval and timing in triggered periodic superradiance
Hideaki Hara, Riku Omoto, Noboru Sasao +6
To achieve more controllable development of coherence in solids, we investigated the effect of a trigger laser tuned to the superradiance transition wavelength on periodic superrad…
Analytical and numerical studies of periodic superradiance
Hideaki Hara, Yuki Miyamoto, Junseok Han +6
We conduct a theoretical study to understand the periodic superradiance observed in an Er:YSO crystal. First, we construct a model based on the Maxwell-Bloch equations for a reduce…
A method to detect the VUV photons from cooled Th:CaF crystals
Ming Guan, Michael Bartokos, Kjeld Beeks +13
Thorium-229, with its exceptionally low-energy nuclear excited state, is a key candidate for developing nuclear clocks. Th-doped CaF crystals, benefiting from calcium f…
Measurement of cesium electric quadrupole transition probabilities using fluorescence spectroscopy
Jing Wang, Yuki Miyamoto, Hideaki Hara +3
Fluorescence spectra of the ( and = 3/2, 1/2) electric quadrupole transition of cesium atoms have been observed with a heated cesium vapor cell…
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…
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…
