Abstract :
To optimize the pole shape of quadrupole magnet we have improved the program MULTIMAG. In its new version it can reduce or enhance the different multipole components in the user define `good field region´ by changing the pole shape. This feature improves noticeably the capabilities of MULTIMAG a program developed for design and analysis of magnets used in accelerators and charged-particle manipulation systems. MULTIMAG uses the finite-element technique to calculate magnetic-field characteristics and includes options for 2D- and 3D- modeling. Depending on the required solution accuracy elements of first or second order are used. Very important is here that the mesh for MULTIMAG is automatically generated by the program without any user involvement
