Available in PDF, EPUB and Kindle. Book excerpt: Motivated by their applicability to gamma-ray spectroscopy experiments in space, quantitative studies of radiation damage effects in high-purity germanium detectors due to high-energy charged particles have been initiated with the irradiation by 6 GeV/c protons of two 1.0 cm thick planar detectors maintained at 88°K. The threshold for resolution degradation and the annealing characteristics differs markedly from those previously observed for detectors irradiated by fast neutrons. Under proton bombardment, degradation in the energy resolution was found to begin below 7 x 107 protons/cm2, and increased proportionately in both detectors until the experiment was terminated at a total flux of 5.7 x 108 protons/cm2, equivalent to about a six year exposure to cosmic-ray protons in space. At the end of the irradiation, the FWHM resolution measured at 1332 keV stood at 8.5 and 13.6 keV, with both detectors of only marginal utility as a spectrometer due to the severe tailing caused by charge trapping. The two detectors displayed a significant difference in proton damage sensitivity, which is consistent with fast neutron damage effects. To ensure that detector variability did not influence the comparison of proton- and neutron-induced damage effects, one of the detectors had been used previously in a neutron damage experiment. The threshold for high-energy proton damage was found to be markedly lower, roughly 5 x 107 protons/cm2, compared to 3 x 109 neutrons/cm2 for fast neutrons. Annealing these detectors after proton damage was found to be much easier than after neutron damage. A satisfactory level of recovery after high-energy proton damage can be achieved with in-situ annealing in the range of 100°C.

Book excerpt: Here is the most extensive resource on polymer radiation effects to be available in more than a decade. This new volume reviews the fundamental chemistry and physics of polymer-radiation interaction and examines recent progress in most major areas of the field. Its 38 chapters, written by leading experts from around the world, cover: fundamentals of polymer radiation chemistry; technological applications of radiation to polymers (including radiation processing; radiation curing; sterilization; cross-linking, polymerization, grafting, X-ray resists, and others); and degradation of stabilization of irradiated polymers (including nuclear plants, scintillation detectors for particle physics, and others).

Available in PDF, EPUB and Kindle. Book excerpt: The fast recovery of electron concentration after a burst of 1 MeV electrons (1 mA during 15 microsec) has been studied near 100 degrees K, in high purity n-type Germanium (10 to the 13th power to 3 x 10 to the 13th power Sb/cc). Three different stages have been observed. (1) A fast decrease (10 microsec) of excess carrier concentration. (2) A further decrease below the initial concentration, during 6 ms. This stage can be attributed to fillind of traps either created by irradiation, or grown in the crystal. (3) A return towards the initial concentration, through defect annealing. The time constant, at 100 degrees K, is 24 ms, and the activation energy, near 100 degrees K, is 0.14 eV. This stage appears negligible below 60 degrees K, as expected if it corresponds to the '65 degrees K defect.' This behavior can be interpreted with a model based on the creation of a transient defect, stabilized by electronic capture, and then decaying by the usual annealing process. (Author).
