    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: The invention relates to a radiation detector, an arrangement and a method for an energy-dispersive detection of X-ray photons. X-ray photons are allowed to collide (701) in the radiation detector (201, 601), whereby there are produced (702, 703, 704, 705, 706, 707, 708) observations of the X-ray photons that collided in the detector. According to the invention, there are separately produced observations of X-ray photons (702, 703, 704) that collided in the first detector space (205, 501) of the radiation detector and X-ray photons (705, 706, 707, 708) that collided in the second detector space (206, 502) of the radiation detector. The (712) observations of X-ray photons that collided in the first detector space (205, 501) are ignored, when there is received a simultaneous observation of an X-ray photon that collided in the second detector space.

    摘要: A radiation window foil for an X-ray radiation window comprises a mesh that defines a number of openings (902), said mesh having a first side surface (903) and a second side surface (904). A layer (906) spans said openings. Said layer (906) is on the first side of the mesh but spans said openings at a level closer to the second side surface (904) of the mesh than the first side surface (903) of the mesh.

    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: An X-ray tube includes a cathode, an anode with an electron receiving surface, and a window facing the electron receiving surface of the anode. On the electron receiving surface of the anode it includes a layer of anode material. Deeper in the anode than the layer of anode material, there is a block of attenuator material. The atomic number of the attenuator material is less than one third of the atomic number of the anode material.

    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.
