Development of high resolution detectors for Bragg edge time of flight transmission spectroscopy

DOI

The energy of transmitted neutrons can be obtained from their time-of-flight, simultaneously with the acquisition of the transmission radiographic image by a pixilated detector. From this, the locations of Bragg edges can be measured for each pixel of the radiographic image providing there is enough events acquired in each pixel. The combination of both spectroscopic and transmission information enables high spatial resolution studies to be carried out on material composition, phase transitions, texture variations, as well as strain analysis, as long as the resolution and statistics are favorable. In the proposed experiments we will continue the characterization and optimization of our detection system in transmission spectroscopy configuration with time of flight. Series of measurements will be performed with samples of different materials, varying texture, and composition.
