Description
For the design and layout of accelerators "Beam-Dynamics" calculations have to be performed in order to show the functionality of the machine and to determine the specifications and requirements of the different accelerator components (vacuum-system, magnets, power supplies, correctors, etc.). For these calculations the so called "Beam-Dynamic-Codes" are used, as for example: MAD, DIMAD, BETA, OPA, AT, TRACY, ELEGANT, ACCELERATICUM. In a collaboration of SLS, SOLEIL, SPEAR III, APS, BINP and ALBA a comparison of these codes has been made for the lattices of SOLEIL, APS and ALBA. In a first step the linear lattice parameters have been calculated and in a second step the nonlinear parameters as tune shifts with energy and amplitude as well the dynamic aperture including energy deviations. Within this seminar the results of this comparison will be presented and discussed.
