Cooled by miniature, high-reliability mechanical cooler that runs from internal battery, supplemental external battery, line power, or automobile power outlet, all with automatic switchover.! HPGe gamma spectrometer has 16k resolution digital electronics with ORTEC Low Frequency Rejector (LFR) digital noise filter to minimize microphonic noise. Full hardware specifications are provided in Chapter 8. HPGe Detector The trans-SPEC-DX-100 detector is a P-type (“ORTEC GEM”) crystal, nominally 65 mm × 50 mm.
The trans-SPEC-N detector is an N-type crystal, nominally 67 mm × 69 mm. The instru- ment is cooled by a small, high-reliability Stirling cooler that draws less than 25 W when opera- ting —. The trans-SPEC can be purchased with built-in global positioning (GPS) hardware. The GPS coordinates are captured at the start of each acquisition and saved in the spectrum file if you select the ORTEC file format during setup. I n t e g e r. S P C In addition, the trans-SPEC can be equipped with IEEE 802.11 wireless connectivity.
The trans-SPEC can operate for about 3 hours on the internal lithium-ion battery. The auto- mobile accessory adapters (included) allow you to use 12-V power from an automobile battery. In addition, ORTEC offers optional battery belts to extend the remote operation time. Spectrum Collection, Storage, Transfer, and Viewing The live (currently displayed) spectrum and all the associated information are held in the spec- trometer’s memory. 931042C / 1014 1.
INTRODUCTION Stored spectra are retained until you delete them, even when the trans-SPEC is powered off and has been disconnected from all external and battery power. Available storage capacity depends on the computer controlling the trans-SPEC and on the capa- city of the memory card.
If sub- sequent ORTEC applications are added to your instru- ment, our “Launcher” interface (Fig. 1) runs first, making it easy to switch between ORTEC identifier programs and exit to Windows Mobile.
931042C / 1014 1. INTRODUCTION 1.7. Should You Take a Computer Into the Field? The trans-SPEC is designed for standalone field use. However, there are a few situations where an external computer is useful. One use is for advanced analysis of the spectra where the Nuclide Report does not show enough detail.

The internal battery provides approximately 3 hours of operation. The internal battery cannot be used to start the cooler or cool the detector from room-temperature; external power is required. 931042C / 1014 2.
THE TRANS-SPEC When connected to an external battery, the trans-SPEC relies on external power until the exter- nal voltage drops below 9 V. It then switches to the internal battery. The instrument makes the transition smoothly, and there is no effect on the energy resolution. If you begin with both bat- teries fully charged, the sum of the two battery capacities will be achieved.
