16 engineering design improvements over previous models.
Gamma Gage II represents a series of engineering improvements over the highly successful Gamma Gage of which many thousands are deployed daily in portable high resolution spectroscopy applications. These improvements have been implemented specifically in response to requests from users of the original Gamma Gage.
Gamma Gage II is intended for most any situation in which it is necessary to "take the instrument to the sample."
Examples of such measurements are found in many waste assay and site characterization measurements, as well in nuclear materials holdup, and portable safeguards isotopic ratio measurements. In some cases, a Gamma Gage dewar is an excellent solution when space/weight is at a premium, for example, in Whole Body Counting applications or in some multi-detector research applications, although increasingly, electrical cooling is a viable alternative in these.
The integral LN2 dewar is available in a variety of hold times to suit the measurement constraints on size/weight and holding time.

Figure 28. 6-mm Diameter SLP Detector Element
ORTEC SLP Series Lithium-Drifted Silicon X-Ray Detectors provide the spectroscopist with a highly sensitive, premium performance research tool for detecting x rays from a nuclear accelerator, radioactive source, or x-ray tube. The energy range of detection (Fig. 25) is from 30 keV down to 1 keV, depending on the thickness of the beryllium window.
The x-ray detector consists of a lithium-drifted silicon crystal and a cryogenically-cooled-FET, a high-gain, low-noise hybridized preamplifier in a PopTop capsule with a thin Be entrance window. The ORTEC Si(Li) detector crystal is manufactured under an exclusive process. Special techniques for lithium drifting result in a negligible detector element dead layer whose characteristics will not change even if the detector is stored at room temperature.

Si(Li) detectors, which cover the energy range from a few hundred eV to 50 keV or so, are used in a wide variety of applications including x-ray fluorescence, x-ray microanalysis, PIXE, EXAFS, x-ray diffraction, and M%uFFFDssbauer.
The finest in semiconductor technology and cryogenics, combined with advanced signal processing electronics give CANBERRA Si(Li) detectors solid performance and reliability. Unlike early Si(Li) detectors and unlike those manufactured by some companies today, CANBERRA Si(Li) detectors are stable at room temperature so they can be shipped and stored without LN2.
CANBERRA Si(Li) detectors are available in two versions. The standard detector uses conventional geometry and a gold surface barrier entrance window. The Super Si(Li) uses a proprietary geometry and entrance window. This, along with a special shaping amplifier, improves resolution by at least 10 eV (FWHM) and increases the peak/background by about ten-fold to greater than 10,000:1.
CANBERRA offers a full complement of signal processing and data acquisition electronics. The detector includes a low-noise preamplifier of the pulsed-optical feedback type. This pre-amplifier employs a specially fabricated FET which is cooled along with the detector in a cryostat.
