چکیده

We describe a method for numerical construction of a symplectic map for particle propagation in a general accelerator lattice. The generating function of the map is obtained by integrating the Hamilton-Jacobi equation as an initial-value problem on a finite time interval. Given the generating function, the map is put in explicit form by means of a Fourier inversion technique. We give an example which suggests that the method has promise.

A Method for Finding 4d Symplectic Maps with Reduced Chaos

We have previously proposed a method for finding integrable, four-dimensional symplectic maps. The method relies on solving for parameter values at which the linear stability factors of the fixed points of the map have the values corresponding to integrability. We suggest that this method be applied to accelerator lattices in order to increase dynamic aperture. We have now implemented a numeric...

High-order Computation and Normal Form Analysis of Repetitive Systems

Besides the mere tracking of individual particles through an accelerator lattice, it is often helpful to study the corresponding phase space map relating initial and final coordinates. Recent years have seen an advance in the ability to compute high-order maps for rather complex systems including accelerator lattices. Besides providing insight, the maps allow treatment of the lattice without ap...

Lego: a Modular Accelerator Design Code

An object-oriented accelerator design code has been designed and implemented in a simple and modular fashion. It contains all major features of its predecessors: TRACY and DESPOT. All physics of single-particle dynamics is implemented based on the Hamiltonian in the local frame of the component. Components can be moved arbitrarily in the three dimensional space. Several symplectic integrators a...

Of Extended Generating Functions

The time t maps of Hamiltonian flows are symplectic. The order n Taylor series approximation with respect to initial conditions of such a map is symplectic through terms of order n. Given an order n Hamiltonian symplectic map, there are a variety of procedures, called symplectification methods, which produce exactly symplectic maps with Taylor series that agree with the initial Taylor map throu...
