MARGIE (Minute-of-Arc Resolution Gamma-ray Imaging Experiment) is a large area (~10⁴ cm²), wide field-of-view (~1 sr), hard X-ray/gamma-ray (~20--500 keV) coded-mask imaging telescope capable of performing a sensitive survey of both steady and transient cosmic sources. MARGIE has been selected for a NASA mission-concept study for an Ultra Long Duration (100 day) Balloon flight. The MARGIE collaboration is evaluating an approach to the central large-area position-sensitive detector based on segmented inorganic scintillators (BGO and CsI) viewed by position-sensitive photomultiplier tubes (PSPMTs). We describe the experimental setup and procedure, and compare laboratory results to predicted performance derived from simulation studies.
