    Abstract: An x-ray radiator has a vacuum housing that can rotate around an axis, a cathode that thermionically emits electrons upon irradiation thereof by a laser beam, an anode that emits x-rays upon being struck by the electrons, an insulator that is part of the vacuum housing and that separates the cathode from the anode, electrodes or terminals to apply a high voltage between the anode and the cathode to accelerate the emitted electrons toward the anode to form an electron beam, a drive arrangement for rotation of the vacuum housing around its axis, an arrangement for cooling components of the x-ray radiator, and an arrangement that directs and focuses the laser beam from a stationary source that is arranged outside of the vacuum housing onto a spatially stationary laser focal spot on the cathode.

    Abstract: A radiation converter includes a radiation absorber for generating light photons dependent on the intensity of incident radiation following the radiation absorber by a photocathode, an electrode system for accelerating the electrons emanating from the photocathode onto an electron detector for generating electrical signals dependent on the incident electrons, and an electron multiplier arranged between the photocathode and the electron detector. The electrons emanating from the photocathode are multiplied by the electron multiplier.

    Abstract: An X-ray diagnostic installation has a storage luminescent screen for the latent storage of an X-ray image, an X-ray exposure unit for generating an X-ray beam, a readout system for causing the storage luminescent screen to luminesce by being scanned with a radiation source, a detector for acquiring the light emitted by the storage luminescent screen, and an image playback system. In a first operating mode, the X-ray exposure unit produces X-ray images with a first dose and the readout system implements a fast readout of the image area of the storage luminescent screen with low resolution. In a second operating mode, the X-ray exposure unit produces X-ray images in a limited region with a higher dose compared to the first dose, and this region of the image area of the storage luminescent screen is read out with high resolution.

    Abstract: A holding device for a motor, particularly for an electric fan wheel motor of a heating or air condition system of a motor vehicle, having an adapter which can be fixed on an exterior motor component and surrounds it at least partially on the circumference side, as well as having a motor holder connected with the adapter and having at least one vibration-uncoupling supporting element. According to the invention, primarily axially stressed supporting elements are provided between axially spaced parts of the adapter, on the one hand, and of the motor holder, on the other hand, or between the exterior motor component and a bottom surface of a cup-shaped adapter which can be fixed thereto, or such supporting elements which are mounted radially between motor holder fastening arms and adapter holding fingers, while being fastened on one part and engaging form-lockingly in receiving pockets on the other part. The holding device may be used, for example, for holding a fan motor of a motor vehicle air-conditioning system with a low vibration transmission and a reduced contribution to the noise development caused by the motor holder.
