Abstract[English]
Techniques are described for a charged particle optical apparatus that includes a loop of solid material that encloses a bore and a wire winding poloidally wrapped around the loop surrounding the bore. A current is applied to the toroidal winding generating a magnetic field inside the loop along a toroidal direction of the loop and generating magnetic vector potential within the bore. When charged particle(s) pass through the bore of the loop, the magnetic vector potential focuses the charged particles based on the focal point of the charged particle optical apparatus.[French]
L'invention concerne des techniques pour un appareil optique à particules chargées qui comprend une boucle de matériau plein entourant un trou et un bobinage de fil enroulé de manière poloïdale autour de la boucle entourant le trou. Un courant est appliqué au bobinage toroïdal, générant un champ magnétique à l'intérieur de la boucle le long d'une direction toroïdale de la boucle et générant un potentiel vecteur magnétique à l'intérieur du trou. Lorsqu'une ou plusieurs particules chargées passent à travers le trou de la boucle, le potentiel vecteur magnétique concentre les particules chargées sur la base du foyer de l'appareil optique à particules chargées.
