milliprobe, n.|ˈmɪlɪprəʊb|
[f. milli- + probe n.]
Any instrument for analysing small amounts of material; spec. a form of spectrometer in which a narrow beam of accelerated protons (or other subatomic particles) is directed at the specimen and the spectrum of the resulting fluorescence is analysed, frequently used to study delicate or valuable objects.
1963Banks & Hall in Archaeometry VI. 31 Both Dr. E. T. Hall and W. J. Young suggested at the I. I. C. Rome Conference in 1961, that many of these difficulties could be overcome if one used a curved-crystal spectrometer arrangement. The Laboratory has put this idea into operation in designing its new X-ray spectrometer, the ‘Milliprobe’. 1966Ibid. IX. 131 X-ray fluorescent analysis by a milliprobe. 1970Phil. Trans. R. Soc. A. CCLXIX. 139 A new variation in emission spectrometry has been provided by the development of the ‘Laser milliprobe spectrometer’. 1978Analytical Chem. L. 1644/1 X-ray milliprobes used in these studies have been designed specially and fabricated at Bell Laboratories. 1987Nature 16 July 195/2 Using a proton milliprobe, collimated to 1.0 mm × 0.5 mm (because the width of the lines on the map is of the order of 0.5 mm), Cahill and his team carried out 159 analyses of the parchment and ink of the map. |
