Nature of problem:
The reconstruction of the longitudinal phase space density of particles in a synchrotron from one-dimensional bunch profile data.
A hybrid algorithm  which combines particle tracking with iterative Algebraic Reconstruction Techniques (ART) .
The particle tracking is very elementary and the only parameter variations considered are constant first-order time derivatives of the dipole magnetic field and rf voltages of the accelerator.
Arbitrarily complex rf systems can be catered for by modifying a small part of the code. Likewise the method may be extended to cover any non-rigid body for which a model governing its deformation exists.
Execution time depends strongly on the resolution and number of images required and on the accelerator parameters involved, but is typically several minutes per image.
