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’. 1970 Philos. Trans. (Royal Soc.) A. 269 139 A new variation in emission spectrometry has been provided by the development of the ‘Laser milliprobe spectrometer’. 1987 Nature 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.
