Abstract

By using the micro-pulling down (μ-PD) method, the barium magnesium fluoride (BaMgF4) single crystalline scintillator was produced. The crystal was cut and mirror polished to the physical dimensions of 1×2×10 mm3 for examination of scintillation properties. BaMgF4 demonstrated ∼70% transmittance in wavelength range above 170 nm, and strong emission peaking around 205 nm was observed under X-ray excitation. The absolute light yield of BaMgF4 was 1300±100 ph/MeV, and the decay time profile showed two components as 0.57±0.01 (70%) and 2.2±0.31 (30%) ns at room temperature.
