In the preparation of the lectures on emittance measurements I had help from several people. In particular I would like to thank: Dr. Peter Forck, GSI Darmstadt, Germany, whose lecture notes (http://www-bd.gsi.de/conf/juas/juas.html) were used as a basis for the lectures. Dr. H. Braun PSI Villigen Switzerland, who gave me his transparencies on emittance measurements for the CERN School of Accelerators (CAS) on beam diagnostics, Gif-sur-Yvette 28.May - 7.June 2008 Dr. Brennan Goddard, CERN, Geneva, Switzerland who prepared the slides on filamentation Dr. Tom Shea, ORNL, who assembled the experimental setups for the laboratory session several collegues at CERN who gave me photographs or slides, used during the lecture.
