Beam dynamics simulations of long time-scale (compared to betatron and synchrotron oscillations) processes, such as IBS, various types of cooling, rest-gas scattering, internal target, beam losses, etc.
Every new algorithm which is implemented is benchmarked against the code from which it was taken. For example, the algorithm of tracking of beam distribution called "modeled beam" was benchmarked against code SIMCOOL (Novosibirsk) from which it was taken.
Benchmarking against accelerator experiments :
IBS in RHIC, Cooling in Fermilab, Cooling in CELSIUS, Cooling in COSY and many others.
