The invention is directed to a manipulator for an optical apparatus including a particle-optical apparatus. The manipulator is especially a diaphragm or specimen manipulator in an electron microscope. The component (), which is to manipulated, is accommodated by a transfer body () movable relative to a spatially-fixed component () and the transfer body () includes a composite material having a high thermal conductivity while simultaneously having a vanishing or negative thermal expansion coefficient in the direction of the connecting axis (B&#x2014;B) between the component () and the spatially-fixed component ().

Manipulator for an optical or particle-optical apparatus

An apparatus, which generates ionizing radiation, includes a column having a sandwich-like configuration. The column includes one or more tubes and a layer of a cured epoxy-resin mixture containing a heavy metal. The layer of epoxy-resin mixture adheres to the tube or, if the several tubes are provided, the layer adheres to the tubes. In this way, the layer defines a unit with the tube or tubes. The configuration of the apparatus provides a configuration, which is tight against exiting X-ray radiation, also in regions of breakouts and tube transitions.
