Over the years, ELSE NUCLEAR gained expertise in both neutron and gamma spectrometry, developing highly-specialized measurement systems for industry, environmental agencies, research centers and universities worldwide. All spectrometry systems’ capabilities are thoughtfully validated with dedicated experimental tests and Monte Carlo simulations.
The GSU gamma spectrometry units employ a 3″x3″ NaI(Tl) crystal coupled to a photosensitive detector (either PMT or SiPM) and an MCA. The detector is installed in a 5 cm thick lead shielding well, with additional inner layers of tin and copper for enhanced background reduction.
The Bonner Sphere Spectrometer consists of an array of He-3 proportional counter thermal neutron detectors, each housed in a spherical HDPE moderator of different diameters.
BSS is proposed in two main configurations, adjustable according to the requirements, for single or multiple detectors.
The single-sphere neutron spectrometer SP2 is a unique device that allows performing active neutron spectrometry measurements by employing a single instrument instead of the usual multi-sphere BSS.
The W-PIE neutron spectrometer is a unique device designed for on-line neutron spectrometry measurements. The system features an extremely high counting efficiency, making it suitable to perform neutron spectrometry and absolute flux measurement for applications such as:
B-RAD is a hand-held radio-isotope identifier (RIID) for gamma dose rate survey and spectrometry measurements, specifically designed to work in magnetic fields up to 3 T. For comparison, conventional devices fail to operate at intensities as low as 0.1 T.
HERMES systems are rugged, portable units for radiation detection, designed and tailored for a wide range of operational scenarios such as gamma and neutron detection, dose rate measurement, gamma spectroscopy and more. HERMES systems are suited for emergency response activities, as they are mounted inside robust and high-IP technical cases, which can be handheld or vehicle-mounted.
HERMES GSU is a portable gamma spectrometry system designed for rapid and precise in-field analysis of environmental samples. As part of the HERMES product line, it features a rugged, modular, and self-contained design housed in a high IP-rated technical case, ensuring durability and reliability in demanding conditions.
HERMES GSU quantifies isotope activity concentrations based on a rich built-in, yet fully-editable, isotope library. Its portability and autonomous operation make it ideal for both routine monitoring and emergency response scenarios.
