Abstract

This work presents the design and development of a CdTe sensor, Medipix3RXv2 readout ASICs photocounting detector of 55 pm pixel size arranged in an arc modular distribution for its use in X-ray Pair Distribution Function (PDF) applications at the Diamond Light Source (DLS) synchrotron. This contribution highlights the concept and technical solutions adopted for this new detector which include the development of a fibre optic link between the detector head and the readout FPGA cards. This solution enables a considerable reduction in the weight and size of the detector head.
