    摘要: A method for obtaining information about an unknown neutron source or an unknown material interacting with a known neutron source comprises the steps of: (a) providing a radiation detector capable of delivering a neutron energy information allowing the production of response histogram(s) as a function of neutron energy, (b) measuring with said radiation detector neutrons being emitted from said unknown neutron source or from said unknown material, (c) deriving from said measured neutrons a neutron energy spectrum, especially in form of a histogram, (d) normalizing said energy spectrum or histogram relative to a parameter or set of parameters derived from the measurement of a different variable, (e) comparing said normalized energy spectrum or histogram with known energy spectra or histograms, and (f) drawing conclusions on the basis of said comparison about the nature of the unknown neutron source or unknown material.

    摘要: The invention relates to a tube coupling (TC2) for connecting an object (22) to one end of a tube (20) in a UHV tight manner, withstanding pressures up to several hundred bars and accommodating temperature differences from heating or cooling, said tube coupling (TC2) comprising said tube (20) and a tube fitting (10), wherein said tube fitting (10) comprises a basically cylindrical body (11) with a first central bore for receiving said tube (20), such that said tube (20) is axially supported by a radially extending shoulder (18) at the inner end of said first central bore, and wherein said tube (20) is pressed with its end face against said radially extending shoulder (18) by means of a gripping arrangement (13, 14, 15). The vacuum capability is achieved with simple components by providing a gasket (21) between said end face of said tube (20) and said radially extending shoulder (18) at the inner end of said first central bore (16).

    摘要: The invention relates to a method for obtaining information or signatures about the presence or the nature of a nuclear radiation source, especially in a homeland security application, said nuclear radiation source emitting in a time or angle correlated manner at least a first radiation and a second radiation. The method includes the steps of detecting said first radiation with at least one first radiation detector and detecting said second radiation with at least one second radiation detector. The detection of said second radiation is triggered by said detection of said first radiation in a manner that is adapted to the radiation's correlation structure, thereby increasing the signal-to-background ratio for the detection of said second radiation.
