Abstract

1312704 Analysis OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE GmbH 7 May 1970 [12 May 1969] 22102/70 Heading G1A In a method of analysing a material or constituent of a process by bombarding the material or constituent 3 with a beam 5 of photons and monitoring the scattered radiation 7, the bombarding photon beam is produced by interacting a beam of relativistically accelerated elementary particles with the photons of a laser beam so that the particles transfer energy to the photons to produce the bombarding photon beam. In determining the composition of a melt 3 in a steel converter 1 the energy of the initial elementary particle beam is chosen so that the bombarding beam 5 comprises mono-energetic y-rays. The energy of this beam 5 is preferably kept below the nuclear threshold so that the scattered radiation 7 comprises only y-radiation and not neutrons and/or protons. A pulse height analyser is used in the circuit of the detector 8 to make a quantitative analysis of element(s) in the melt 3. The detector circuit also contains an analogue (14) and a digital (12) computer which control a process control unit (13) which in turn controls the O 2 supply rate and pressure to the furnace and the position of the burner lance 2 Fig. 2 (not shown). The detector 8 may be a scintillation or semiconductor detector, e.g. Ge (Li), Si (Li), in Sb, CdTe, Na I or plastic. The bombarding beam 5 may be applied intermittently. The method may be applied to biological processes e.g. determination of iron in the blood, sodium in fingernails, iodine in the thyroid glands, and fluorine in teeth.
