Energy linearity of high-purity germanium detectors in the region of the Ge K-absorption edge: experimental results
Non-linearities in the energy response of gas detectors in the regions of the absorption edges of the detection medium are well documented. Monte Carlo calculations show that the non-linearity results from differences in efficiencies for converting absorbed radiation into ionisation for different atomic sub-shells. Energy non-linearity in germanium-based solid-state detectors in the region of t...
متن کاملCharacterization of SuperCDMS 1-inch Ge Detectors
The newly commissioned SuperCDMS Soudan experiment aims to search for WIMP dark matter with a sensitivity to cross sections of 5 x lO^̂ ĉm^ and larger (90% CL upper limit). This goal is facilitated by a new set of germanium detectors, 2.5 times more massive than the ones used in the CDMS-II experiment, and with a different athermal phonon sensor layout that eliminates radial degeneracy in positi...
متن کاملDigital Timing Algorithm for High Purity Germanium Detectors
The next generation of γ-ray detector arrays will be composed of large volume high purity germanium (HPGE) detectors that are electronically segmented. These detectors will be able to track γ-rays as they Compton scatter within the crystal and between adjacent crystals, eliminating the need for Compton suppression detectors and improving angular resolution. The new arrays will have much higher ...
متن کاملThe response of high-purity germanium detectors to X-rays with energy in the region of the Ge K-absorption edge.
The response of a high-purity germanium detector to X-rays in the 8-15-keV energy region has been investigated. The w-value and energy resolution dependencies on the X-ray energy have been studied. No abrupt variation of w is observed at the germanium K absorption-edge (11.104-keV). The detector energy resolution follows a characteristic linear dependence on Ex(-1/2) over the whole energy range...
متن کاملThree-dimensional Si/Ge quantum dot crystals.
Modern nanotechnology offers routes to create new artificial materials, widening the functionality of devices in physics, chemistry, and biology. Templated self-organization has been recognized as a possible route to achieve exact positioning of quantum dots to create quantum dot arrays, molecules, and crystals. Here we employ extreme ultraviolet interference lithography (EUV-IL) at a wavelengt...
