- IBS: shorter bunch length lead to stronger increase in epread -> gets more important for short pulses like in flashRT #IBS

- micro-bunching
- übergangsstrahlung, bremsstrahlung?
- TODO:
- summarize which effects could be relevant, then see which are considered at the moment for medical linacs, especiallty flash/microbeams, and then it is clear which need to be considered, thats what I plan to do....
