Symplectic Integrator for Particle Tracking in Complex Magnetic Field
نویسندگان
چکیده
High field wigglers for synchrotron radiation production have usually rather complex distribution of magnetic field, and particle motion through it can hardly be treated analytically. This paper concerns a simple and reliable receipt for a symplectic algorithm to track a particle through such fields. Input data for numeric integration are taken directly from results of magnetic mapping or simulation of a 2D field values array. A 3pole 7 T superconducting wiggler is considered as an example.

Dirac Brackets from Magnetic Backgrounds
In symplectic mechanics, the magnetic term describing the interaction between a charged particle and an external magnetic field has to be introduced by hand. On the contrary, in generalised complex geometry, such magnetic terms in the symplectic form arise naturally by means of B–transformations. Here we prove that, regarding classical phase space as a generalised complex manifold, the transfor...
متن کاملExtraction of Lie Map from Realistic 3d Magnetic Field Data*
We present a method to extract the Lie map from the realistic magnetic field data of arbitrary magnet. The multi-particle tracking results are fitted into Taylor maps, which can be factorized into a Lie map by using DragtFinn's method [1]. This method is validated by comparing against the COSY-infinity code [2] for a soft-edge quadrupole model. Examples of extracting the symplectic maps for the...
متن کاملExplicit time-reversible orbit integration in Particle In Cell codes with static homogeneous magnetic field
A new explicit time-reversible orbit integrator for the equations of motion in a static homogeneous magnetic field —called Cyclotronic integrator— is presented. Like Spreiter and Walter’s Taylor expansion algorithm, for sufficiently weak electric field gradients this second order method does not require a fine resolution of the Larmor motion; it has however the essential advantage of being symp...
متن کاملHigh order time integrators for the simulation of charged particle motion in magnetic quadrupoles
Magnetic quadrupoles are essential components of particle accelerators like the Large Hadron Collider. In order to study numerically the stability of the particle beam crossing a quadrupole, a large number of particle revolutions in the accelerator must be simulated, thus leading to the necessity to preserve numerically invariants of motion over a long time interval and to a substantial computa...
متن کاملA Differential Algebraic Integration Algorithm for Symplectic Mappings in Systems with Three-Dimensional Magnetic Field
A differential algebraic integration algorithm is developed for symplectic mapping through a three-dimensional (3-D) magnetic field. The self-consistent reference orbit in phase space is obtained by making a canonical transformation to eliminate the linear part of the Hamiltonian. Transfer maps from the entrance to the exit of any 3D magnetic field are then obtained through slice-by-slice sympl...
