Book excerpt: A 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 carriers which are swept out by an electric field. This is accomplished by reverse biasing the detector with approxi mately 100 v/mm of intrinsic material. The total amount of charge swept out is proportional to the energy dissipated in the intrinsic region. This may include the total energy of the photon, but gen erally somewhat less. The Ge(Li) device is a semiconductor p-n device with a very large intrinsic region between the positive carrier region and the negative carrier region (P-I-N). The fabrication of this device consists of three major steps: the diffusion of the lithium into the p-type germanium to give an n-type surface region, the drifting process to obtain the intrinsic region as deeply as possible, and the surface preparation. There are numerous procedures for the various steps as well as criteria for material selection and the preparation of the materials.

Available in PDF, EPUB and Kindle. Book excerpt: Six nomographs which can facilitate the fabrication and testing of lithium-drifted germanium gamma-ray detectors (Ge(Li) detectors) have been constructed which relate the following parameters:time, temperature, applied bias, and drifted depth:lithium mobility, crystal resistivity, and oxygen concentration; area, capacitance, and drifted depth for planar Ge(Li) detectors; drifted depth, length, and capacitance for coaxial Ge(Li) detectors; total spectral resolution; system noise, and detector resolution; gamma-ray energy, and effective Fano factor.The use of these nomographs is described and illustrative examples are given.(Author).

This book was released on 1966 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis the method of fabrication of lithiumion-drifted detectors and their application to gamma-ray spectrometry of Si^°(d*n7)P^1 and Be^(a*ny)C12 reactions are described. 3 The planar-type detectors up to 5 cm sensitive 3 volume and a coaxial type detector of 10 cm sensitive volume have been fabricated. But due to the high leakage current caused by surface contamination* only a few planar-type detectors have been successfully tested. The intrinsic resolution of these detectors for 66l KeV gamma-ray of Cs1^ vary between 3.4 KeV to l6.7 KeV. The energy resolution of the best detector obtained was 3.4 KeV and 7*7 KeV for gamma-rays of energies 0.122 and 2.62 MeV respectively. This detector exhibited an absolute efficiency of 70$ for 122 KeV* decreasing to 0.8$ near the 2 MeV region. 3 A detector with sensitive volume of 3 cm has been 30 31 used to study the gamma-rays produced in the S1J (d*ny)P^ reaction with the hope of determining the branching ratios of 31 PJ gamma-ray transitions. But the low efficiency of the detector above 4 MeV did not allow such measurements to be made. In 12 addition* the 4.43 MeV gamma-ray for C produced by the Q 12 Be^(a*n7)C reaction was studied. This gamma-ray exhibited a Doppler shift and broadening which is discussed as a means of obtaining the lifetimes of nuclear excited states.
