ANTECH Series 200
High Sensitivity Large Sample Calorimeter

Absolute measurement of sample thermal power

Comprehensive User friendly windows based User Interface Software

Reduced Criticality hazard as water is not used as a heat sink

Measurement times with equilibrium sample power prediction of between 2-4 hours

Total mass of Pu determined with error propagation when Pu isotopic data is provided on a file or ‘on-line’ from ANTECH Pu Gamma-ray Isotopic Measurement System

Comprehensive and traceable electrical calibration capability reduces dependence on Pu standards

Highly transportable trolley mounted system

The transportability of the instrument allows the user to move the calorimeter to the measurement site and thus limits the need to move special nuclear material. At the same time, instrument transportability does not compromise measurement accuracy. The design has application to a wide range of measurement requirements including international safeguards measurements, shipper-receiver difference measurements, in-plant accountancy measurements and anomaly resolution in passive neutron coincidence counting or segmented gamma-ray scanning. The instrument also has a role in replacing a proportion of destructive assay.

Variations to the standard design for different requirements and for special sample types or sample packaging can be accommodated. In particular the measurement chamber volume may be reduced or increased in size and measurement precision and measurement time may be optimized for a specific limited sample power range. Smaller sample diameter custom systems achieve significantly better precision and accuracy at lower measurement powers (e.g. <10 mW).
