Software tools

The lattice design tool used is MadX, available from MadX produces can output

  • a flat lattice description in a madx input language (.seq files). No drift, no lines, basically a set of variables and element declaration and a sequence of elements with their s position.
  • a flat table file (.tfs files) that includes either element parameters (including drifts) and optics function or element name and assigned magnetic error and misalignments.

The following python libraries can be used to parse those file:
