Title (EN) MAGNETIC FIELD COMPENSATION IN A LINEAR ACCELERATOR
(FR) COMPENSATION DE CHAMP MAGNÉTIQUE DANS UN ACCÉLÉRATEUR LINÉAIRE
Abstract:
(EN) A system has a linear accelerator, ion pump and a compensating magnet. The ion pump includes an ion pump magnet position, an ion pump magnet shape, an ion pump magnet orientation, and an ion pump magnet magnetic field profile. The compensating magnet has a position, a shape, an orientation, and a magnetic field profile, where at least one of the position, shape, orientation, and magnetic field profile of the compensating magnet reduce at least one component of a magnetic field in the linear accelerator resulting from the ion pump magnet.
(FR) Un système comprend un accélérateur linéaire, une pompe ionique et un aimant de compensation. La pompe ionique comporte une position, une forme, une orientation et un profil de champ magnétique d'aimant de pompe ionique. L'aimant de compensation a une position, une forme, une orientation et un profil de champ magnétique. La position et/ou la forme et/ou l'orientation et/ou le profil de champ magnétique de l'aimant de compensation réduisent au moins une composante d'un champ magnétique dans l'accélérateur linéaire provenant de l'aimant de la pompe ionique.
