ISOCS Calibration Software
|
Features
- No radioactive sources needed for accurate efficiency calibrations
- Works over a wide range of geometries
- Calibrations valid from zero distance out to 500 meters
- Calibrations valid from 45 to 7000 keV
- Calibrations accurate to within a few percent
- Calibrations accurate at any angle from detector, not just on centerline
- Eliminates the cost of purchasing radioactive standards, creating custom distributions, and radioactive waste disposal
- Results are available within a few seconds
- Operates with any size or type of Germanium detector which has been characterized by CANBERRA
- Ideal for in situ applications, where large and various sample types are often encountered
- Includes predefined geometry templates for twenty common container shapes and sample distributions
- Sample size can be point-like, or up to 500 meters in size
- Includes library of common materials and tools to create new materials
- Works with cylindrical collimators with conical holes, and rectangular collimators with trapezoidal holes
- Includes predefined collimator entries for ISOCS Shield
- Custom templates can be provided to meet special application needs
- Multi-Efficiency program allows creation of compound efficiencies for multiple detectors, multiple locations or multiple sources
- Easy to use Windows®-based graphical user interface with extensive automatic error checking
- User-defined templates containing all static information about a sample may be saved and easily be recalled
- Geometry Composer Report summarizing all information defined for a given geometry can be displayed and printed
- Only a few physical sample parameters (e.g. size, distance from detector, etc.) are needed to tailor a template to a sample
- Ability to vary assumed sample characteristics (e.g. density, container wall thickness, etc.) makes it ideal for “What if…?” analyses
- Resulting calibrations may be stored, recalled, and used just like those generated by traditional calibration techniques
- Calibrations are in CANBERRA CAM file format, and can be transferred to any Genie software for analysis, e.g. Genie-ESP
- Companion software to S574 LabSOCS that is optimized for laboratory calibrations
Description
The ISOCS (In Situ Object Counting System) Calibration Software brings a new level of capabilities to Germanium gamma sample assay by eliminating the need for traditional calibration sources during the efficiency calibration process. By combining the detector characterization produced by the MCNP modeling code, mathematical geometry templates, and a few physical sample parameters, the ISOCS Calibration Software gives you the ability to produce accurate qualitative and quantitative gamma assays of most any sample type and size (Figure 1).

ISOCS Calibration Software is launched from the Desktop, used for Data Entry,
and then generates the Genie 2000 Efficiency Curve.
In addition to saving money by eliminating the need to purchase (and later dispose of) many calibration sources, ISOCS Calibration also saves time. Instead of hours spent in traditional source preparation and long calibration counts, an ISOCS Calibration for a new geometry requires only a few seconds of computer calculations.
The secret to this capability is twofold:
- The energy/efficiency/spatial response profile of the Ge detector has been characterized by CANBERRA with the well-known MCNP Monte Carlo modeling code.
- Mathematical templates have been created for most of the sample geometries that will be encountered - planar surfaces, rectangular boxes, barrels, pipes, etc.
To a basic geometry template, add the specifics for a given sample - its size, density, distance from the detector, etc. - and the ISOCS Calibration Software generates a custom efficiency calibration specifically tailored for that detector and sample. The remainder of this document will describe how this is done and how the various standard geometries templates are used.
