§16§This is the proceedings of the fourth school in a series ofspecialized courses organized by CERN's CAS and the AmericanUSPAS. It deals with intensity limitations. The contributionthoroughly edited for this publication fall into thefollowing categories: self and environmental fields -coherent instabilities and their simulation - beam-beaminteraction - other multi-particle effects - beam sourcelimitations - engineering limitations.This exposition of the inner working of high-intensityparticle beams addresses particle physicistsas well asthose that commission new machines. The lecturers werechosenas being at the forefront of latest developments inthis field. §04§Welcome address.- Intensity limitations in circular particle accelerators.- Wake fields and impedances.- Bench methods for bean-coupling impedance measurement.- Coherent beam instabilities.- Observation and correction of instabilities in circular accelerators.- Some longitudinal dynamics of bunched beams.- Low energy aspects of circular accelerators.- High current beam transport in linear accelerator structures.- Observation of high current effects in high energy linear accelerators.- Observations of the beam-beam interaction in Hadron colliders.- Beam-beam effects in electron-positron storage rings.- Coherent beam-beam effects.- Beam-beam phenomena in linear colliders.- Engineering limitations of proton colliders.- Engineering limitations with electrons.- Intrabeam scattering.- Ions and neutralization.- Beam loading in RF cavities.- High-brightness injectors for Hadron colliders.- The next linear collider.- Hadron collider luminosity limitations.- Physics and technology challenge §04§s of $$Bbar B$$ factories. §02§These are the proceedings of the fourth school in a series of specialized courses organized by CERN's CAS and the American USPAS.
