High-light-yield calcium iodide (CaI2) scintillator for astroparticle physics

“…We also obtained good resolution, namely 3.2% @ 662 keV. Table 1 and [10] summarize the measurement results and compare them with those for other scintillators.…”

“…We also obtained good resolution, namely 3.2% @ 662 keV. Table 1 and [10] summarize the measurement results and compare them with those for other scintillators. In dark matter search experiments, we need to separate the nuclear recoil signal produced by WIMP scattering from the environmental gamma-ray background.…”

Comparative pulse shape discrimination study for Ca(Br, I)$_2$ scintillators using machine learning and conventional methods

“…We conducted a comparative study of particle identification by waveform using our own calcium-based halide scintillators (CaI 2 , CaBr 0.7 I 1.3 , and Eu2% doped CaBr 0.7 I 1.3 ). In our previous research, CaI 2 achieved a high light yield and excellent energy resolution [3]. Additionally, we reported the good pulse shape discrimination (PSD) capability of CaI 2 using a simple double gate method [4].…”

“…The quartz ampoules and Pt heaters were surrounded by alumina insulators to control the temperature gradient along the growth direction. The details of the crystal growth setup are described in [6]. The quartz ampoule was heated to the melting point of CaI 2 , CaBrI, and CaBrI:Eu, and then the ampoule was pulled down at a rate of 0.003-0.009 mm/min.…”

Dark matter search with high purity NaI(Tl) scintillator

“…The design of the high-selective detector system with NaI(Tl) scintillator is discussed with KamLAND group. New functional scintillators with a high performance of particle identification have been developed; they have a large scintillation output and good performance of particle identification by pulse shape discrimination [32,33].…”
