Multipole Field Electromagnetic Launchers (MFEML) is one of the radial electromagnetic launching mechanisms, which can propel a payload for long distances. This paper proposes formulae for inductance based on the magnetic flux distribution in the coils of MFEML. Flux lines flow is sectionalized, for each section reluctance formulae is derived based on the position of the projectile. Based on the principles of the Lorentz equation, magnetic forces are calculated. This paper presents an electrical and magnetic equivalent circuit of MFEML. The velocity and force characteristics are obtained for the proposed formulae. The results are validated using Finite element analysis.

Quadrupole Lenses

The precision doublet of magnetic quadrupole lenses is presented. The doublet yoke and poles made from a single piece of soft magnetic iron. Doublet manufacturing technology provides of alignment of the geometric axes in the lenses with an accuracy of a few microns. The doublet geometry was chosen to obtain the maximum magnetic induction at the poles for a given radius of the lens aperture as a result of numerical simulation. An experimental study of the doublet properties was carried out using a setup for field reconstruction technique for magnetic quadrupole lenses. The relative position of the physical axes of the lenses (the geometrical location of points with zero magnetic induction) and the magnitudes of the parasitic multipole field components were determined.
