CERN-GSI Electron Cloud Workshop

7 Mar 2011, 08:00 → 8 Mar 2011, 13:00 Europe/Zurich

6/2-024 - BE Auditorium Meyrin (CERN)

Frank Zimmermann (AB/ABP), Giovanni Rumolo (CERN), Oliver Boine-Frankenheim (GSI)

The bilateral CERN-GSI Electron Cloud Workshop will review the status of CERN and GSI electron cloud studies and define the strategy for future developments in terms of simulation tools, diagnostics and mitigation techniques. The Workshop is supported by CERN and GSI, and sponsored by the European networks EuCARD and ACCNET.
