Implications of neutrino species number and summed mass measurements in cosmological observations
N. Sasao, M. Yoshimura, M. Tanaka
We confront measurable neutrino degrees of freedom and summed neutrino mass in the early universe to particle physics at the energy scale beyond the standard model (B…
Periodic super-radiance in Er:YSO crystal
Hideaki Hara, Junseok Han, Yasutaka Imai +5
We observed periodic optical pulses from an Er:YSO crystal during irradiating with an continuous-wave excitation laser. We refer to this new phenomenon as "periodic super-radiance"…
High-sensitivity low-noise photodetector using large-area silicon photomultiplier
Takahiko Masuda, Ayami Hiramoto, Daniel G. Ang +9
The application of silicon photomultiplier (SiPM) technology for weak-light detection at a single photon level has expanded thanks to its better photon detection efficiency in comp…
SiPM module for the ACME III electron EDM search
A. Hiramoto, T. Masuda, D. G. Ang +9
This report shows the design and the performance of a large area Silicon Photomultiplier (SiPM) module developed detection of fluorescent light emitted from a 10 cm scale volume. T…
Generation of Twisted Gamma-Rays via Two-Photon Transition
Motomichi Tashiro, Noboru Sasao, Minoru Tanaka
We present a new and efficient method of generating twisted gamma rays utilizing highly accelerated helium-like ions; they are excited to a chosen state by irradiating two optical…
Estimation of radiative half-life of Th by half-life measurement of other nuclear excited states in Th
Y. Shigekawa, A. Yamaguchi, K. Suzuki +8
We perform coincidence measurements between particles and rays from a U source to determine the half-lives of the excited state in a Th nucleus. We first pr…
