    • The invention relates to an analyzer for the identification of explosives and/or chemical warfare agents, with a neutron source which causes the emission of characteristic &ggr; quanta, whereby the analysis system consists of a mobile frame to which a neutron source and a detector as well as a holder for the object are attached, with a neutron generator which contains deuterium as the target, generates neutron pulses by periodically repeated, pulsed bombardment of the target and is controlled so that short neutron pulses are emitted and repeated periodically, whereby the detector is controlled so that in cycles it detects &ggr; quanta promptly emitted from the object due to inelastic neutron scattering and neutron capture, within at least two consecutive temporal measurement windows, whereby the first measurement window at least partially overlaps temporally the neutron pulse and the subsequent second measurement window does not, whereby in the first measurement window &ggr; quanta are essentially detected due to inelastic neutron scattering and in the second measurement window they are detected due to neutron capture.
    • 本发明涉及一种用于识别爆炸物和/或化学战剂的分析仪,其具有引起特征伽玛量子点的中子源,由此分析系统由可移动的框架组成,中子源和检测器 作为对象的保持器,附有包含氘作为目标的中子发生器,通过周期性重复的靶的脉冲轰击产生中子脉冲,并且被控制以使得短的中子脉冲被周期性地发射和重复,由此检测器是 被控制使得在周期内,它在至少两个连续的时间测量窗口内检测由于非弹性中子散射和中子捕获而从物体迅速发射的伽马量子,由此第一测量窗口在时间上至少部分地与中子脉冲和随后的第二测量重叠 窗口不在,其中在第一测量窗口中的gamma量子是 由于非弹性中子散射基本上被检测到,并且在第二测量窗口中,它们由于中子捕获而被检测。
