The operation of semiconductor detectors is summarized in the following points: Ionizing radiation enters the detector's sensitive volume ( germanium crystal) and interacts with the semiconductor material. A high-energy photon passing through the detector ionizes the atoms of the semiconductor, producing electron-hole pairs. The number of electron-hole …

DetailsThe Lithium-Drifted Germanium detector represents the mostadvanced stage in a systematicdevelopment of semiconductor materials anddevices made from them forthe purpose of radiation detection. The semiconductordetector describedherein has a distinct similarity to the gaseous ionization chamber, but its superiority for most applications is …
DetailsThe availability of germanium with less than 1010 acceptors/cm3 has enabled us to fabricate and study the performance of germanium detectors of substantially larger volume than has hitherto been possible except by using lithium-drifting techniques. Detectors having a sensitive volume of up to 25 cm3 have been made. These detectors …

DetailsThe lithium-drifted germanium detector, denoted Ge (Li), is similar in construction to the Si (Li) detector. However, a striking difference is found in the very high lithium mobility in the germanium detector at room temperature. A Ge (Li) detector will be destroyed if it is allowed to warm up from the normal 77 K operating temperature.
DetailsSemiconductor based photon radiation detectors have been evolving for over half a century, with ORTEC pioneering commercial availability for a majority of that time. Initial offerings were based around lithium-drifted germanium Ge (Li) and lithium-drifted silicon Si (Li). Ge (Li) was later replaced with more advanced, high purity germanium (HPGe) detectors.

DetailsA lithium-drifted germanium detector is a semiconductor de vice which operates at liquid nitrogen temperature, and is used for detection of nuclear radiation, mostly gamma ray. The detection occurs when the y-ray undergoes an interaction in the intrinsic or I region of the semiconductor. The interaction results in the pro duction of charge ...
DetailsThe analysis of a 36% high purity germanium system demonstrated the energy calibration drifted an average of 0.014 keV d (-1) to 0.041 keV d (-1) depending upon energy. At 1,332 keV, one day after calibration, it was shown that up to half of the total error in energy calibration was as a result of calibration drift.

The detection occurs when the y-ray undergoes an interaction in the intrinsic or I region of the semiconductor.
DetailsThick planar detectors have been produced by ac drifting. Lithium is diffused on two opposite surfaces of a p-germanium block, thus producing an n+ pn+ structure with two diodes back to back. Drift then proceeds from the two surfaces on alternate half cycles of the ac field. When the two compensated regions meet, one n-contact is removed and …
DetailsTypical detectors are InSb, a photovoltaic indium antimonide detector operated at 77 K, and He Ge, a photo-conductive mercury-doped germanium detector maintained at 15 K by a closed-cycle helium refrigerator... Radionuclidic analyses are performed with either a lithium-drifted germanium or intrinsic germanium detector. The assay for Sr-82 is ...
DetailsLithium-drifted germanium detectors have been fabricated in the form of a cylindrical annulus. The forming of the annular shape was made feasible by using a spark cutting machine. The annular shape, being highly symmetrical, permits standardization of the techniques of gamma spectroscopy.
