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 optical and scintillation properties. BaMgF4 exhibited more than 70 % transmittance in wavelength range from 170 to 2500 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 0.45 (76 %) and 1.4 (24 %) ns at room temperature.
