【 摘 要 】

The U.S. Department of Energy tasked Pacific Northwest National Laboratory to investigate possible technological avenues for substantially advancing the state-of-the-art in gamma detection via large-area plastic scintillators. This letter report describes progress to date on this project. Early phases of the project, which commenced in January 2003, have focused on (1) quantifying the light-collection efficiency in plastic scintillator sheets as a function of photomultiplier tube positioning and edge-area coverage, (2) developing a conceptual design for a demonstration sensor, and (3) conducting initial laboratory setup and preliminary experiments using relatively small plastic scintillators for readout technique development and benchmarking of the modeling studies.
