High-Purity Germanium Detectors
High-Purity germanium (HPGe)
detectors are the recognized gold standard for detection and
identification of characteristic gamma rays from nuclear or radiological
sources. High- Purity Germanium detectors are mostly used for gamma
spectroscopy in nuclear physics, as well as x-ray spectroscopy. SSBI can
offer the optimum detector for a wide range of applications. We use both
p-type and n-type germanium and we use diffused, implanted, and barrier
contacts to achieve this product variety. SSBI Provides a comprehensive
suit of HPGe radiation detector solution covering an extensive range of
energies and a variety of application
In general, Coaxial P-type detectors are suitable for energies of 40 keV to 10 MeV. N-type coaxials extend the range down to 4 keV. For lower-energy gammas, planar detectors are recommended for the 3 keV-1 MeV range, since they have better energy resolution and less sensitivity to high energy background than N-type coaxial detectors.
- Our High purity germanium detectors (HPGe) are not just laboratory instruments. HPGe detector systems can go anywhere in the field to search for and identify suspect sources, such as weapons-grade plutonium or radiological dispersal devices.
- A built-in computer automatically sorts the signals into a gamma-ray spectrum, analyzes it for known nuclides and displays the results.
- Our system is also now available in packaged into a small-held unit.
- Our units can operate on external AC or DC power to cool down the detector to operating temperature, while at the same time charging the batteries.
- The detector systems can then be unplugged from the external power source and operated independently for greater than three hours.
- It doesn’t take a highly trained analyst to interpret the data in the field.
- Portable HPGe detector systems are designed for non-technical users.
- Built-in software can analyze the gamma-ray spectrum reliably and compare the results to a catalog of characteristic peak energies, in order to identify the nuclides in the source.
- Nuclides found are displayed on the screen and alarms can be set for specific sources.
