Topics for Session 1:
Beam loss and emittance growth caused by
(1) Space charge
and resonance trapping,
(2) Electron cloud and resonance trapping;
Influence of working point and chromaticity on beam losses;
Benchmarking of simulation codes & future experiments.
Topics for Session 2:
Impedances -
resistive walls and kickers;
Head-tail dynamics and simulation code benchmarking;
Transverse resistive instabilities and other collective effects;
How does space charge (and electron cloud?) affect the impedance budget in the
different machines?
