Abstract

Multi-energy gamma-ray fields have been imaged with a ring Compton scatter camera (RCC). The RCC is intended for industrial applications, where there is a need to image multiple gamma-ray lines from spatially extended sources. To our knowledge, the ability of a Compton scatter camera to perform this task had not previously been demonstrated. Gamma rays with different incident energies are distinguished based on the total energy deposited in the camera elements. For multiple gamma-ray lines, separate images are generated for each line energy. Random coincidences and other interfering interactions have been investigated. Camera response has been characterized for energies from 0.511 to 2.75 MeV. Different gamma-ray lines from extended sources have been measured and images reconstructed using both direct and iterative algorithms.
