Next Generation Gamma / Neutron
Sensors - Based on IAT Advanced Digital Sensor Interface
Innovative American Technology (IAT)
has completed version 3.0 of our Advanced Digital Sensor
Interface based on high speed digital electronics, firmware and
software. The Digital Sensor Interface (DSI) increases sensor
efficiencies through very high speed signal processing, analog
to digital conversions and highly effective digital filters. The
first sensor systems include composite neutron detectors with
increased efficiency and gamma rejection rates of 99.99999% (one
in ten million).
Typical gamma rejection rates for competing
products are approximately 99.96%, or four gamma detections in
every ten thousand (10,000) gamma events. The advanced
DSI gamma rejection system reduces the gamma interference to one
gamma detection in every ten million (10,000,000) events. This
is a performance improvement factor of more than 1,000 times
when compared to conventional
systems.
The IAT Digital Sensor interface can be applied to a
wide variety of conventional
neutron detector technologies that previously could not meet
gamma rejection rates and neutron detection efficiencies
required for nuclear industry and government applications.
The DSI technology can also be applied to gamma detectors for
increased efficiency and next generation detection materials.
Next generation radiation detection materials provide
simultaneous detection for both gamma and neutron with good resolution for
gamma spectra. The IAT DSI system allows the gamma spectra to be
separated from the neutron counts to enable optimum
sensor performance. The IAT digital pulse shape differentiation (PSD)
process is performed within the DSI module providing gamma /
neutron separation
rates of up to 99.99999%.
The next generation gamma / neutron sensors
will enable new applications and expand the capabilities of the RTIS family of products including: the
Spreader Bar Radiation Verification System (SBRVS), the Straddle
Carrier Radiation Verification System (SCRVS) and the Mobile
Radiation Verification System (MRVS).
