TRANSPORT:
Goes up to 3rd order.
Multiplies successive matrices (tensors).
Allows the user to select magnetic parameters to be varied and properties to be achieved.
Good place to start.
COSY:
Goes up to arbitrary order. (not sure what this means)
Evaluates the transfer tensor for each element.
Multiplies successive matrices (tensors). (I think)
Very powerful, but difficult. The novice user should be very careful. (My opinion!)
Raytracing Codes (SNAKE, RAYTRACE, and GEANT):
Integrates the equation of motion particle by particle through the magnetic system
Should be as good as the magnetic field description.
Slow (but with today’s computing power not really a limitation anymore).
Matrices/Tensors are inferred from the results of the tracings. (e.g. fit with MUDIFI)
