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.

A gamma ray interacting with a scintillator produces a pulse of light that is converted to an electric pulse by a photomultiplier tube (PMT). The PMT consists of a photocathode, a focusing electrode, and 10 or more dynodes that multiply the number of electrons striking at each dynode. A chain of resistors typically located in a plug-in tube base assembly biases the anode and dynodes. Complete assemblies including the scintillator and PMT are available.
The properties of a scintillation material required to produce a good detector are transparency, availability in large size, and large light output proportional to gamma-ray energy. Few materials have good properties for detectors. Thallium-activated sodium iodide [NaI(Tl)] and cesium iodide [CsI(Tl)] crystals are commonly used, as well as a wide variety of plastics. CsI(Tl) and plastics have much faster light decay times than NaI(Tl) and are primarily used for timing applications.
The high Z of iodine in NaI(Tl) crystals result in high efficiency for gamma-ray detection. Resolution for a 3-inch diameter by 3-inch length crystal is typically about 7% for 137Cs and slightly worse for larger sizes. The light decay time constant for a NaI(Tl) crystal is about 0.23 µs. Typical charge-sensitive preamplifiers translate this into an output voltage pulse with a rise-time of about 0.5 µs. Fast coincidence measurements cannot achieve the very short resolving times that are possible for plastic scintillators, especially at low gamma-ray energies.

General descritpion :
The Scienta XES 350 is a state-of-the-art soft X-ray emission spectrometer. It is a grazing incidence spectrometer covering a wide energy range, 50 -1000 eV, at high resolution and sensitivity [J. Nordgren et al., Rev. Sci. Instr. 60, 1690 (1989)]. The Scienta XES 350 is easily adapted to different excitation sources, since the instrument is flange mounted and has an optical axis that is easily adjusted to the excitation source.
The Scienta XES 350 optical arrangement consists of a variable entrance slit, two moveable shutters for grating selection, three spherical gratings, and a 2-D detector that can be moved in a three-axis coordinate system. The Scienta XES 350 can be described as three spectrometers merged into one by having a common entrance slit and a detector that can be aligned to the focal curve (Rowland circle) of the selected grating. The instrument is equipped with a digital CCD-camera data read-out.
Specifications:
- Variable entrance slit: 0 - 90 micrometer
(controlled by a 1" linear manual feedthrough)
- Variable grating illumination width: 0 - 4.5 cm
(controlled by 2 linear 1" manual feedthroughs)
- Adjustable optical axis: ±2°
- Detector rotation: 15°
- Manual (or motor controlled, optionally) XY-tables (400 and 100 mm) with optical scales for positioning of the detector.

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.
