Statement of Work for

High Resolution Computed Radiography System 1.0

SCOPE

The Contractor shall provide a computed radiography (CR) system for use in ordnance inspection at the Naval Surface Warfare Center, Indian Head Explosive Ordnance Technology Division (NSWC IHEODTD). The CR system will be used with energy levels of 60 kV up to 320kV. The CR system will supplement an existing CR scanner so must be the same model since system is already qualified.
