Abstract
A portable instrument designed for use in treaty verification has been developed. A multichannel analyzer connected to a NaI(Tl) detector provides a rate meter, a background analyzer, a plutonium detector, and an energy-windowed scanner. The presence of plutonium is detected by excess counts in the 400 keV region. An energy calibration is automatically determined using either of two calibration sources. The simple operator interface is implemented with four lights and pushbuttons.<>
