The Bigger, the Better
The Target F900 is a radio-nuclide identifier with a large single NaIL™ (NaI:TI, 6Li) detector (2“ x 4“ x 8”) packed into a rugged watertight housing.
The ultra-high-speed electronics in combination with the 2“ x 4“ x 8” NaIL detector delivers superior sensitivity over the unequalled energy range of 10 keV to 10 MeV. The sophisticated and reliable gamma spectroscopy software identifies nuclides in real time and detects thermal and fast neutrons. The field proven quantum gain patented stabilization method maintains excellent identification over the entire temperature range even with extreme temperature cycles. The F900 offers best in class performance with best radiological performance at minimum weight in a very robust (to IP67) and compact form factor.
The hot-swappable battery feature of the F900 enables the standard 20-hour run time to be easily extended without interruption to operation. The remote operating capability further extends the range of applications for which the F900 is ideally suited.
Wide Range of Applications
At less than 7.7 kg (16.9 lbs) the F900 reduces operator fatigue in man borne missions.
A range of application specific stands and adapters drives easy reconfigurability for a wide range of applications. It can be easily mounted to the walls of a pedestrian gateway. The platform will also support mobile applications such as attaching to a vehicle, vessel, robot or UAV.
Quantum Gain Stabilization ™
Excellent gain stabilization is critical to accurate and consistent Radionuclide Identification in unpredictable environments.
The gain stabilization used in the F900 system delivers better stability over large temperature ranges than has previously been available in backpack detection systems. Measured deviations obtained from very taxing temperature cycle testing that simulate extreme operating examples over the entire operating temperature range show deviations of less than 0.5% in peak position.
The patented Quantum Gain Stabilization method is based on methods that derive information dependent upon individual quantum events rather than by measuring gross effects (such as the current flowing through the PMT). In this way we are able to determine both the absolute gain of the PMT and the variation of the light yield from the scintillation crystal.
The rock stable performance of the F900 in all conditions and environments drives superior alarm adjudication in field operation.
One Detector for the entire Gamma-ray Dose Rate Range
Highly sophisticated analog and digital electronics make it possible for the first time to measure a wide gamma dose rate range.
The F900 has a dose rate capability up to 100 mSv/h (10 rem/h) and performs Nuclide ID even with an input count rate of 1M (one million) counts per second. Whether the threat material is characterized by minute traces of material or is masked by very high count rate materials F900 delivers excellent threat detection capability.
One Detector for Gammas and Neutrons
The F900 FinderWear system uses the innovative NaIL single detector for neutron detection and gamma-ray spectroscopy.
The standard NaI(Tl) material is co-doped with a low percentage (of the order of 1%) elemental Lithium that is enriched to 95% of the neutron sensitive radionuclide 6Li. The resulting detector leverages the advantage of the fully industrialized NaI(Tl) spectroscopic gamma-ray scintillator. The pulse shape difference between the light pulses arising from gamma-rays to those from neutrons is so large that simple pulse shape discrimination achieves rejection of false neutron pulses due to gamma-ray events.
In addition to the thermal neutron detection the F900 FinderWear system employs a new method that enables it to detect fast neutrons. The method (patent applied for) relies upon the recoil reactions that occur when a fast neutron interacts with Na nuclei in the NaIL crystal.
Use any mobile device to remote operate the F900.
Connect your Android device with the F900 via Bluetooth. The Target Android app makes your device work as an external display and gives you full control to the F900.
With its built-in Wi-Fi server, the F900 provides an easy way to connect to any Wi-Fi enabled device (e.g. cell phone, tablet, etc).
In this ways it is possible to control the F900 whether used in a man borne application or deployed in response to an event (e.g. pedestrian portal).
Highly Capable Finder Mode
The newly developed pointer mode provides intuitive support to assist the Operator in search for radiological materials.
The finder algorithm fuses data from the GPS, the accelerometer, and the gyro, rapidly directing the Operator to the location of the radiological material.
Perfect Usability in Any Position
Due to the versatility of the F900, it may happen that the F900 is used upside down.
When standing upside down, the F900 rotates its display content, but leaves the button labelling next to the buttons. In this way, the F900 can be safely and easily operated, whether it is in a backpack, on its supplied feet or mounted on a wall.
Built in GPS for Mapping
F900 tracks position, dose rate, alarms, and identifications. Data is compliant with the ANSI N42.42 standard.
Drop-tested up to 1 meter and built to survive rigorous missions
Drop-tested at 1 meter and certified for operation at one meter depth in water assures robust operation even in adverse environmental conditions. The hermetically sealed robust enclosure assures robustness against environmental conditions even at underwater depths of 3.3 feet (1 meter).
Get on board with the built in web interface.
Multiple interface types and the built-in web interface provide a powerful array of reach-back operation options. Transmission of the data from the F900 uses standard industry protocols. State-of-health information is automatically provided and available for transmission enabling a remote technician to diagnose the cause of the failure and to initiate the appropriate action protocol.
No extra software is needed to connect your computer to the F900. With any modern web browser you can download and organize measurement results, set up the instrument or remotely operate the F900.
