Coincidence time resolution (CTR) of 10 ps is an ultimate goal toward reconstruction-less positron emission tomography (PET). One of the ways to enhance the timing performance of the PET detector is to make use of Cherenkov photons which is promptly

X-ray and gamma-ray photons are widely used for imaging but require a mathematical reconstruction step, known as tomography, to produce cross-sectional images from the measured data. Theoretically, the back-to-back annihilation photons produced by po

With the upgradation of detector components, such as scintillators and photodetectors , the PET-image signal-to-noise ratio of time-of-flight positron emission tomography (TOF-PET) systems has been improved, compared to those of ordinary nonTOF-PET s

The light yield (LY) and decay kinetics of a single crystal scintillator of Gd 3 Al 2 Ga 3 O12(GAGG):Ce were measured for 0.662 MeV γ - and 5.48 MeV α -rays between −100 °C and room temperature. As the temperature decreased, the LY increased by

In the CANDLES experiment aiming to search for the very rare neutrino-less double beta decays (0νββ) using 48Ca, we introduced a new shielding system for high energy γ-rays from neutron captures in massive materials near the detector, in addition

We study a strategy to reduce veto-time in the search for neutrino-less double-beta decay (0υββ) with CANDLES-III system. We develop a new likelihood analysis and apply it to our new Run010 data. We show that we can increase the un-vetoed live-tim

A liquid scintillator containing a tetrakis(isopropyl acetoacetato)zirconium has been developed for ZICOS experiment. In order to reach the sensitivity T 1 / 2 0 v ≥ 10 27 years, we have to use tone scale of 96Zr and have to reduce 95 % of backgrou
