Title
(EN) MAGNETIC ACHROMATIC MASS SPECTROMETER WITH DOUBLE FOCUSING
(FR) SPECTROMETRE DE MASSE MAGNETIQUE ACHROMATIQUE A DOUBLE FOCALISATION
Abstract
(EN)
The invention relates to an achromatic magnetic mass spectrometer (200), for example of the SIMS type with double focusing, characterised in comprising means (202, 212, 215, 221 ) for cancelling the four second order aberrations and means (201, 222) for cancelling off-axis achromatic and for modulating mass dispersion.
(FR)
Spectromètre de masse magnétique (200) achromatique, par exemple de type SIMS à double focalisation, caractérisé en ce qu'il comprend des moyens d'annulation (202, 212, 215, 221 ) des quatre aberrations du second ordre, et des moyens (201, 222) d'annulation de l'achromatisme hors d'axe et de modulation de la dispersion en masse.
