Trans-SPEC-X-N battery powered portable HPGe gamma spectrometer

Trans-SPEC-X-N is an all-in-one portable high-resolution gamma spectrometer suitable for on-site measurements. The device can be used as an independent device for collecting energy spectra on site, connected to a computer via USB, network cable or Wi-Fi, and controlled and analyzed using ORTEC's MAESTRO-Pro (included), GammaVision, Isotopic or other software.

The Trans-SPEC-X-N is structurally identical to the popular “gold standard” DETECTIVE-X radionuclide identifier in nuclear security measurement. Also similar to ORTEC's traditional TRANS-SPEC-100T and MICRO-TRANS-SPEC equipment, the Trans-SPEC-X-N focuses on on-site energy spectrum collection rather than nuclide identification. Trans-SPEC-X-N models offer guaranteed resolution performance and come equipped with MCA emulation software.

Function

• Main energy spectrum display interface: Log/Lin, Zoom, Region of Interest (ROI), Start, End, Clear acquisition data and save energy spectrum
• Peak/ROI data display interface: center channel address, FWHM, start/end channel address, total/net peak area and count rate
• Changeable spectral marker data interface: energy, track address, count
• Changeable status bar interface: select any 2 of the following - live time, real time, remaining live time, remaining real time, remaining battery life, count rate and ROI count rate
• MCA control interface: ADC conversion channel addresses (upper and lower limits), amplifier gain coarse and fine adjustments, baseline recovery (auto, fast, slow), gain and zero stabilizers, high voltage switch
• Pre-acquisition parameter interface: live time, real time, ROI peak and ROI integral
• Health status interface: ±12 V, +3.3 V, detector temperature, case temperature, cold finger temperature and high voltage
• Security interface: Password protected user/admin mode, lock/hide spectrum display during acquisition
• Energy scale: Quadratic fitting of energy and road address
• External Interfaces: Compatible with all ORTEC CONNECTIONS related applications such as MAESTRO, MAESTRO-Pro, GammaVision, Isotopic, Renaissance, and A11 Tools Package.

Detector/Cooler

crystal	Coaxial N-type high-purity germanium, typical size diameter 65 mm, length 50 mm
relative efficiency	Typical ≥ 50% (ANSI/IEEE 325-1996).
resolution	≤1600 eV @ 122 keV, ≤2.5 keV @ 1332 keV (FWHM guaranteed value under condition).
Peak shape	Typical 1.9 (FWTM/FWHM).
Cold fingers and chillers	Ultra-high vacuum structure, equipped with high reliability, low energy consumption Stirling refrigerator. This structure ensures that the equipment can be turned on and off at any point in time without the need for a complete temperature cycle, that is, no need for cooling or rewarming, which satisfies the flexibility of use of portable equipment on site.
Cooling time	The cooling time is affected by the ambient temperature, generally it takes 7 hours at 25°C.
