【 摘 要 】

We report an investigation on optical and scintillation properties and radiation hardness of four 20 cm long BSO crystals grown at SIC for the HHCAL detector concept. Their optical and scintillation properties, such as longitudinal transmittance, light output and light response uniformity, were measured before and after γ-ray irradiation. Progresses are observed in optical quality, light output and radiation hardness. Their use for HHCAL concept is discussed.
