Mass spectrometer with great luminosity

Description

In this spectrometer, the aperture aberrations in the radial plane are corrected, together with the inclination in the image plane. The correction is made by acting, at least, on three parameters: curvature radii of the magnetic sector input and output sides and an hexapole set between the magnetic sector and the image plane; this means, during the development, resolving a three equation system in which variables are the three parameters. Application to every spectrometer is possible

Abstract (French)

Dans ce spectrometre les aberrations d'ouverture dans le plan radial sont corrigees, de meme que l'inclinaison dans le plan image. La correction se fait en agissant au moins sur trois parametres: les rayons de courbure des faces d'entree et de sortie du secteur magnetique du spectrometre et un sextupole dispose entre le secteur magnetique et le plan image; ceci revient, lors de la mise au point, a resoudre un systeme de trois equations dans les variables sont les trois parametres. L'application a tous les spectrometres de masse est possible
