OBS

Cet instrument est idéal pour déterminer précisément la distribution de traces chimiques variées à l'intérieur d'un matériau [...] Il comporte un accélérateur électrostatique [...] À l'aide d'une tension électrique pouvant aller jusqu'à 4 millions de volts, celui-ci confère une énorme énergie cinétique à des ions hélium ou hydrogène. Un système comprenant des tubes sous vide, diverses bobines magnétiques et autres lentilles électrostatiques sert à convoyer et préparer le faisceau d'ions. Celui-ci, d'une surface de l'ordre du micromètre carré, est dirigé vers l'échantillon dont il faut analyser la composition.
