Uranium Measurements and Attributes
It may be necessary to find the means to determine unclassified attributes of uranium in nuclear weapons or their components for future transparency initiatives. We briefly describe the desired characteristics of attribute measurement systems for transparency. The determination of uranium attributes; in particular, by passive gamma-ray detection is a formidable challenge
Real-time computer analysis for nuclear material detection. Part 3. Nuclear instrumentation interface
An electronic interface between a Digital Equipment Corporation (DEC) LSI-11 microcomputer and a LeCroy Research Systems model 3001 qVt multichannel analyzer is described in detail. This interface provides for 16-bit parallel data transfer from the memory of the analyzer to the memory of the computer. An unusual feature of the interface is a provision that allows storage of counts of logic pulses (e.g., from radiation detector discriminators) in the first 16 channels of the analyzer's memory. A further provision allows use of a LeCroy printer and display interface that is designed specifically as a companion module to the qVt analyzer
