AURAS 3000 is a highly automated system for measuring a variety of sample sizes and forms (bags, boxes, barrels, and B25 containers), with densities approximately in the range 100 kg/m3 to 2000 kg/m3. The system uses four mechanically cooled HPGe spectrometers.
The main parts of AURAS 3000 are:
- Main rail with moving platform for materials to be monitored
- Cross rail with two detectors towers (2 HPGe each) which can be independently moved along the vertical
- Remote PC control station and local PLC interface
The operator starts the scan through the LabVIEW user interface, and chooses the container type to be scanned from a set table. This results in an adjustment of the detector position under computer control as required by the counting geometry.
The container is weighed automatically by the online weighing system to a resolution of 1 kg.
The spectra from each detector/position combination are saved and analyzed individually using the gamma spectrometry waste assay software. An individual assay value for the container is calculated, based on each detector/position individually, and an averaged value is also calculated. Individual and averaged MDA values are also calculated. Detection limits better than 0.01 Bq/g are generally achievable in a 40 minute count for low density materials.
Please note that AURAS 3000 stations can be adapted to specific requirements through a customization of the basic configuration here described. The customization can be applied to the mechanical layout of the rails (length) and/or to the measurement equipment.
