Conceptual Design of a Superconducting Quadrupole with Elliptical Acceptance and Tunable Higher Order Multipoles
AbstractFor charged particle beams that are wider in the dispersive plane compared to the
transverse plane it is cost efficient to utilize magnets that accept beams with elliptic
cross section. In this paper we presents the conceptual design of a quadrupole magnet
with elliptic cross section and with tunable higher order multipoles. The design consists
of 18 superconducting race-track coils placed on two hollow concentric rhombic prism
To compute the magnetic field for the proposed design a new method of calculating
2D and 3D fields for the air core magnets based on differential algebra (DA) techniques
is developed. We will present the new method and discuss its implementation of new
numerical tools based on this method in the code COSY Infinity.
