Dr. Kiran Sonnad, Karlsrhue Institute of Technology (KIT), Karlsruhe, Germany, will give a talk on; "Electron Clouds: Their Diagnostics and Simulation of their Effects"

Electron clouds are known to have detrimental effects over the quality of the beam. They are foreseen to pose problems in several future accelerator facilities and proposed upgrades of existing ones. This presentation will cover aspects of two key areas of electron cloud studies. Their diagnostics using the microwave transmission method and calculation of their effects on the beam. The first part of this talk will discuss the microwave transmission experiments conducted at PEP II, emphasizing on the theory and simulation work that accompanied these experiments. Some attempts at repeating this experiment at the ANKA storage ring will also be discussed. The second part will deal with calculations of emittance growth due to electron cloud effects. This part will show results of a study done for the planned upgrade of the Fermilab main injector and also some studies on comparison of results obtained from different codes.
