N2 - We are developing a high-light-yield calcium iodide (CaI2) scintillator for astroparticle physics experiments. This paper reports our CaI2 scintillator crystal's scintillation performance. It achieved high light emissions (2.7 times those of NaI(Tl)) at a wavelength that was well within the photomultiplier's sensitivity region. We also performed a pulse shape discrimination study using alpha and gamma-ray sources, confirming after a brief analysis that CaI2 has excellent pulse shape discrimination potential.
