We report on the development of a new, large area, powdered scintillator screen based on Lu 2 O 3 (Eu). As reported earlier, the transparent ceramic form of this material has a very high density of 9.4 g/cm 3 , a high light output comparable to that of CsI(Tl), and emits in a narrow spectral band centered at about 610 nm. Research into fabrication of this ceramic scintillator in a large area format is currently underway, however the process is not yet practical for large scale production. Here we have explored fabrication of large area screens using precursor powders from which the ceramics are fabricated. To date we have produced up to 16 × 16 cm 2 area screens with thickness in the range of 18 mg/cm 2 . This paper outlines the screen fabrication technique and presents its imaging performance in comparison with a commercial Gd 2 O 2 S:Tb (GOS) screen. |
