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.
