Beschreibung
The projected SIS-100 synchrotron at FAIR will provide heavy ion beams
for many different user experiments. Most of these experiments will require
beams from slow extraction. Slow extraction is mainly characterized by the
amount of uncontrolled beam losses and temporal microscopic structures on the
extracted beam also referred to as spill. For both characteristics, predictions
are done based on particle tracking simulations. The requirements to both types
of simulations are different which results in differences in the computational
demands.Determining particle losses requires the application of the full lattices
with a comprehensive model of magnet errors and all apertures, whereas spill
structures can be characterized using a less precise lattice model.
On the other hand, spill structure simulations require realistic particle
numbers and time intervals, which can be reduced when only looking for
particle losses.
