Micro-trans-SPEC HPGe Detector and Cooler The Micro-trans-SPEC HPGe detector is an ORTEC GEM Series P-type crystal that is 50 mm in diameter x 33 mm (±10%) in length with ~13% relative efficiency1 in a “hardened” cryostat cooled by an integrated, low-power, Stirling-cycle cryo-cooler. All Micro-trans-SPEC 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 curve is shown in figure 1. The crystal is housed in an...

Nuclide Report Menu items are designed to closely follow the original trans-SPEC logic. The menu structure, including all text menus and screens from the original design are converted to enhance operator familiarity, but with the attractiveness and utility of the new display technology. Real Time Activity Calculations . . . No PC Required! A Micro-trans-SPEC 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...

State-of-Health Display Instrument State-of-Health and Status The Micro-trans-SPEC 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 Micro-trans-SPEC, can read the state-of-health status parameters, and display them on a laptop, if connected. They may also be displayed on the Micro-trans-SPEC status screen. User-developed packages may read the status register through the Micro-trans-SPEC for maintaining the...

MENU FUNCTIONS INTERNAL HPGe DETECTOR Dimensions (nominal) 50 mm diameter x 33 mm (±10%) length. Coaxial construction. P-type high-purity germanium. Relative Efficiency 13% typical (ANSI/IEEE 325-1996). Resolution <1450 eV @ 122 keV and <2.15 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-cycle cooler. The cryostat design is such that the Micro-trans-SPEC may be switched off at any time and power subsequently re-applied without having to wait for a full thermal cycle...
