Abstract
We are developing a one-sided tomographic method for imaging prompt gamma rays, without moving the source, sample, or detector, in a standard prompt gamma activation analysis (PGAA) setting. Dual-plane pixelated CZT detectors developed from a commercial system with external timing synchronization electronics are used to measure prompt gamma rays that are scattered in the first plane and subsequently absorbed in the second plane. Tomographic images have been reconstructed from the 2.2 MeV gamma rays from H in 3-mm plastic balls using inter-plane events for the first time, demonstrating the feasibility of spatially resolving mm scale H features.Proceedings Title
