A method is for manufacturing a multilayer radiation window for an X-ray measurement apparatus. The method includes: producing a gas diffusion stop layer made of silicon nitride on a polished surface of a carrier; producing at least one combined layer on an opposite side of the gas diffusion stop layer than the carrier; attaching the combined structure including the carrier, the gas diffusion stop layer, the at least one combined layer to a region around an opening in a support structure with the at least one combined layer facing the support structure; and etching away the carrier. The at least one combined layer includes: a light attenuation layer made of aluminium, and a strengthening layer. A radiation window is manufactured with the method.

Method for manufacturing a multilayer radiation window and a multilayer radiation window

A radiation window foil is provided for an X-ray radiation window. It includes a continuous window layer with a first side and a second side. A first mesh or grid layer is stacked on or bonded to the first side of the continuous window layer. A second mesh or grid layer is stacked on or bonded to the second side of the continuous window layer.

Reinforced radiation window, and method for manufacturing the same

In a method for manufacturing a radiation window there is produced a layered structure where an etch stop layer exists between a carrier and a solid layer. A blank containing at least a part of each of the carrier, the etch stop layer, and the solid layer is attached to a radiation window frame. At least a part of what of the carrier was contained in the blank is removed, thus leaving a foil attached to the radiation window frame, wherein the foil contains at least a part of each of the etch stop layer and the solid layer.

Method and arrangement for manufacturing a radiation window

A fuel injection arrangement for a piston engine, the arrangement comprising an injector nozzle () for injecting fuel into the combustion chamber () of the cylinder. A Theological actuator () is arranged in connection with the injector nozzle (), the actuator comprising a space () containing Theological fluid and an apparatus () by means of which the viscosity of the Theological fluid can be changed for controlling the fuel injection.
