    摘要: The present invention concerns an arrangement for the measurement of absorbed dose at a given distance from a radioactive source. The arrangement comprises a detector body (1) of ionization chamber type, comprising two electrode elements (5, 6) arranged at a distance from each other and a measuring chamber (7) arranged between these, containing a medium that constitutes a volume that responds to radiation, a second chamber (12) arranged at a distance from the measuring chamber (7) comprising means for recording changes in the medium, a flow passage (13) that is arranged to pass through one of the electrode elements (5, 6) and to constitute a connection that allows the flow of fluid between the measuring chamber (7) and the second chamber (12), and where the detector body (1 ) comprises a through bore, an aperture (2), in which the radiation source is arranged during measurement or through which the radiation source is displaced during measurement. The invention concerns also the use of the arrangement.

    摘要: An alpha detector (10) for application in areas of high velocity gas flows, such as smokestacks and air vents. An odd-numbered plurality of spaced apart signal collectors (13) are placed inside an enclosure, which would include smokestacks and air vents, in sufficient numbers to substantially span said enclosure so that gas ions generated within the gas flow are electrostatically captured by the signal collector means. Electrometer means (17) and a voltage source (16) are connected to the signal collectors to generate an electrical field between adjacent signal collectors, and to indicate a current produced through collection of the gas ions by the signal collectors.

    摘要: A radiation source arrangement causes interaction between pump radiation (340) and a gaseous medium (406) to generate EUV or soft x-ray radiation by higher harmonic generation (HHG). The operating condition of the radiation source arrangement is monitored by detecting (420/430) third radiation (422) resulting from an interaction between condition sensing radiation and the medium. The condition sensing radiation (740) may be the same as the first radiation or it may be separately applied. The third radiation may be for example a portion of the condition sensing radiation that is reflected or scattered by a vacuum-gas boundary, or it may be lower harmonics of the HHG process, or fluorescence, or scattered. The sensor may include one or more image detectors so that spatial distribution of intensity and/or the angular distribution of the third radiation may be analyzed. Feedback control based on the determined operating condition stabilizes operation of the HHG source.
