Topics:

Simulations of electron cloud build up, decay time, clearing gap
Effective transverse and longitudinal wake fields induced by the cloud
Simulations and analytical treatments of transverse instabilities  
Coherent tune shift and incoherent tune spread
Simulations of possible cures or remedies
Plasma approaches to the electron-cloud problem
Synergies between electron cloud, impedance, space charge and beam beam

Goals:

Benchmark simulations against beam observations and against each other
Determine which simulation approaches best represent reality
Document present understanding and determine important open questions
Develop a programme for future research and development 
Strengthen and expand international collaborations for this work
