Electron clouds (EC) can be the source of coherent instabilities and emittance growth in intense ion beams in synchrotrons. The electron are produced at the wall by secondary emission or by residual gas ionization. The cross sections for residual gas ionization by highly charged heavy ions are several orders of magnitude larger than for protons. Here we present simulation studies for the EC build-up in the drift sections and for the corresponding beam stability issues in SIS-18 and SIS-100.
