Battery-Powered, Portable HPGe Gamma Spectrometer “In-Situ High Purity Germanium Gamma Spectroscopy in a digital, battery powered instrument.

• No LN2 — Miniature, high-reliability, Stirling-cycle cooler eliminates the need for LIQUID NITROGEN; detector element is encapsulated in high reliability, low loss, all-metal sealed cryostat. • High Sensitivity — Large (>40% relative efficiency) HPGe detector. • High Stability — Digital electronics give you the solution for the toughest analysis in the toughest conditions. • Bright and Clear — VGA resolution display with touch sensitive operator screen. • All-in-one Integrated Package — Rugged and compact with no interconnections — easy to setup and go. • Smart — Nuclide ID and activity...

trans-SPEC-DX-100T HPGe Detector and Cooler The trans-SPEC-DX-100T HPGe detector is an ORTEC GEM Series P-type crystal that is 65 mm in diameter x 50 mm in length and >40% relative efficiency.1 The large HPGe crystal increases sensitivity and reduces time-toMDA. The “over-square” geometry means best absolute efficiency up to in excess of 2 MeV. All trans-SPEC-100 instruments use nominally identical germanium crystals. A cutaway drawing showing the construction materials is available on request from ORTEC and is suitable for most Monte-Carlo modeling programs. A typical relative efficiency...

trans-SPEC-DX-100T Real Time Activity Calculations . . . NO PC Required! A trans-SPEC-DX-100T can perform simple nuclide activity calculations using internally stored calibration information, at the touch of a button, and all without the use of an attached PC. Everything is easily managed: the library for analysis, displayed peak labels, unit labels and calibration parameters. The parameters are all easily created and downloaded by MAESTRO (MCA emulation software) to the trans-SPEC-DX-100T, or entered directly. The parameters can be changed in the field to adapt to changing needs. Activity...

trans-SPEC-DX-100T Instrument State-of-Health and Status The trans-SPEC-DX-100T HPGe detector incorporates "SMART-1™" diagnostics, which verify that the instrument is operating properly. State-of-health and instrument status is available at a glance. CONNECTIONS programs, such as MAESTRO which is included with the trans-SPEC-DX-100T, can read the state-of-health status parameters, and display them on a laptop, if connected, or they may be displayed on the trans-SPEC-DX-100T status screen. User-developed packages may read the status register through the trans-SPEC-DX-100T for maintaining the...

SPECIFICATIONS INTERNAL HPGe DETECTOR Dimensions 65 mm diameter x 50 mm length nominal. Coaxial construction. P-type high-purity germanium. Relative Efficiency >40% typical (ANSI/IEEE 325-1996) Resolution <1600 eV @ 122 keV and <2.3 keV @ 1332 keV (FWHM Warranted at optimum settings) Peak Shape 1.9 typical (FWTM/FWHM) Cryostat and Cooler “Hardened” cryostat with high reliability, low power Stirling cooler. The cryostat design is such that the trans-SPEC-DX-100T may be switched off at any time and power subsequently re-applied without waiting for a full thermal cycle (complete warm up before...

Status/Marker Line Sets up the Status Line at the top of the spectrum display and the marker line at the bottom to show a selection of the following parameters: Status line, two of: Live time, Real time, Live time remaining, Real time remaining, Battery time remaining, Count rate, Count rate in ROI. Marker line, two of: Marker location (energy), Marker location (channel), Marker channel counts Spectra Settings 1) Ask for Sample Description on save 2) Set a default Sample Description 4) Set a file save format 5) Display a stored spectrum Nuclide Report Displays a list of predefined nuclides...

Cool Down Time The high reliability cooler is designed for continuous operation. Between measurements the unit is powered from a dc supply, car battery or other high capacity device. Initial cool down time depends on ambient temperature, but is typically <12 hours at 25°C. SOFTWARE Trans-SPEC-DX-100T is fully supported by the latest versions of the highly successful MAESTRO MCA Emulator (included) as well as ORTEC Gamma Spectroscopy packages such as GammaVision for generalized HPGe spectrum analysis, FRAM and MGAHI for Pu and U isotopic ratio analysis and ISOPlus for in-situ waste assay...
