Nonlinear and collective phenomena in beam physics

The participants were presented with a choice of four groups, each addressing a particular problem. For each group there was a Speaker, who gave the opening lecture, and a Coordinator, who led the discussions and presented a summary of the work on the last day. The Workshop was organized in such a way as to leave as much time as possible to discussions and to minimize the number of formal plenary talks. The Group on Single Particle Dynamics was charged with review of the status and the discussion of new ideas on the nonlinear dynamics of a single particle in accelerators. The Group on Production and Dynamics of High Brightness Beams covered the advances on production, acceleration, transport, and monitoring of high brightness beams, including coherent and radiation effects. The Group on Beam Dynamics in Plasmas covered the subjects of Plasma Lenses, Electron Beam Driven Wakefields, Laser Wakefields, Self-Modulated Laser Wakefields, Crossed Beam Wakefields, and the generation, acceleration, and focusing of low emittance, high energy, high current short pulses. The charge to the Group on Plasma Phenomena in Beams was to survey the status and recent ideas on transverse and longitudinal oscillations in high density relativist beams, including parametric instabilities and filamentation
