The new transparent ceramic GLO Transparent Ceramic Scintillator provides dramatically improved throughput for MeV radiography and cone-beam computed tomography. It has been scaled up to 12” x 12” optically transparent sheets that are mechanically tough and radiation hard. GLO offers spatial resolution that is better than the available glass scintillators for lens-coupled radiography, while its combined light yield and stopping power improvement results in >7x greater scanning speed, with higher contrast performance. Currently employed industrial X-ray computed tomography systems for imaging of high-attenuating, high-density components such as rocket motors, engines, turbines, automotive assemblies and heavy machinery are costly to operate since they take so long to acquire useful imagery. Implementation of the GLO scintillator will allow an image that used to take a full day to be acquired in one hour, permitting more components to be imaged cost-effectively, leading to rapid manufacturing feedback for quality control and enabling the production of high-reliability components and the development of new capabilities such as real-time CT imaging.
