Description
A prototype X-ray imaging system, using the principle of tomographic energy dispersive diffraction imaging (TEDDI) has been developed at the University of Manchester's School of Materials. The non-destructive 3D imaging system makes use of a state of the art collimator array and a pixelated Si energy resolving detector. A proof of concept for the system has successfully been carried out using metal, polymer and organic samples being exposed to a white X-ray beam from a synchrotron source. The new rapid TEDDI system is limited to thin, low density materials due to the low stopping power of Si at higher X-ray energies. In this presentation the results of substituting Si for CdZnTe as the active detection element and resulting limitations to the key parameters of energy resolution and count rate, for the detectors will be presented. A new ASIC and detector system for the rapid TEDDI measurements has been designed using our initial findings. This design will also be discussed.
