摘要： A gas tight radiation window membrane comprises a layered diffusion barrier with a reactive metal layer (201) covered on both sides by cover layers (202, 203). An originally continuous carrier layer (101) can be made a mesh that has openings coincident with openings of a reinforcement grid (105), while the gas tight diffusion barrier (107, 507) spans as a continuous film over said openings in said mesh.

摘要： A drift detector produces an indication of an occurred hit of a quantum in the detector element. For neutralising accumulated charge in the detector element, indications of occurred hits are used to trigger pulses of deliberately increased neutralisation current into the drift detector for the duration of a limited time interval. Alternatively such triggering may be based on the operation of a timer.

摘要： 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.

摘要： An X-ray fluorescence analyzer device comprises an X-ray source and a sample window. Between the X-ray source and the sample window there are a collimator plate with a plurality of microscopic pores and an annular plate comprising material essentially opaque to X-rays. The annular plate defines an area transparent to X-rays. The pores in said collimator plate let through collimated X-rays radiated by said X-ray source towards said sample window. The area transparent to X-rays in said annular plate spatially limits in a transverse direction a beam of X-rays radiated by said X-ray source towards said sample window.
