  • Publication number: 20110284978
    Abstract: A radiation converter includes a directly converting semiconductor layer, wherein the semiconductor layer includes grains whose interfaces at least predominantly run parallel to a drift direction—constrained by an electric field—of electrons liberated in the semiconductor layer. in at least one embodiment, the charge carriers liberated by incident radiation quanta are accelerated in the electric field in the direction of the radiation incidence direction and on account of the columnar or pillar-like texture of the semiconductor layer, in comparison with the known radiation detectors, cross significantly fewer interfaces of the grains that are occupied by defect sites. This increases the charge carrier lifetime/mobility product in the direction of charge carrier transport. Consequently, it is possible to realize significantly thicker semiconductor layers for the counting and/or energy-selective detection of radiation quanta.

In at least one embodiment, the semiconductor material includes a dopant in a dopant concentration and defect sites produced in a process-dictated manner in such a way that the semiconductor material includes an ohmic resistivity in a range of between 5·107 ?·cm and 2·109 ?·cm. Such a radiation converter material is particularly well matched to the requirements in particular in human-medical applications with regard to the high flux rate present and the spectral distribution of the radiation quanta. In at least one embodiment, the invention additionally relates to a radiation converter and a radiation detector, and a use of and a method for producing such a radiation converter material.

  • Publication number: 20100246758
    Abstract: An X-ray radiation detector is disclosed for detecting ionizing radiation, in particular for use in a CT system, with a multiplicity of detector elements. In at least one embodiment, each detector element includes a semiconductor used as detector material with an upper side facing the radiation and a lower side facing away from the radiation, at least two electrodes, wherein one electrode is formed on the upper side of the semiconductor by a metallization layer, and the sum of all detector elements forms a base, which has a base normal at each point. In at least one embodiment, the invention is distinguished by the fact that the upper side of the semiconductor has a surface structure with a surface normal at each point, wherein the surface normal at least in part subtends an angle to the base normal.

  • Publication number: 20100074397
    Abstract: A method is disclosed for detecting X-ray radiation from an X-ray emitter. In at least one embodiment of the method, an electric pulse with a pulse amplitude characteristic of the energy of a quantum is generated when a quantum of the X-ray radiation impinges on a sensor, wherein a number of threshold energies are predetermined. When the pulse amplitude corresponding to the respective energy is exceeded, a signal is emitted each time the pulse amplitude corresponding to a respective threshold energy is exceeded. At least one embodiment of the method permits reliable and high-quality imaging, even in image regions with high X-ray quanta rates. To this end, at least one of the threshold energies is predetermined such that it is higher than the maximum energy of the X-ray spectrum emitted by the X-ray emitter.

  • Patent number: 7431132
    Abstract: A disc brake comprises a brake carrier, which is fastenable to the vehicle and is provided with bolts at the leading side and at the trailing side of the brake, which during braking take up the forces acting upon the brake linings. The relative dimensions and arrangements of the bolts and of the brake lining are such that, upon introduction of a brake force that is capable of decelerating the vehicle up to a maximum value in the region of 0.1 g, only tensile forces act upon the brake lining.
