Letter of Invitation
A workshop on Nonlinear and Collective Phenomena in Beam Physics is planned for September 2 to 6,
1996, and will be held in Arcidosso, Italy. The workshop will be used to discuss the theoretical and
experimental tools needed to study the beam physics for present and future accelerators. A partial list of
topics includes:
- single particle non linear beam dynamics, dynamic aperture, beam halos;
- beam dynamics problems in plasma lenses, plasma beatwave and wakefield accelerators, including
nonlinear effects and time dependent forces;
- collective effects in the interaction of beams with electromagnetic fields;
- space charge and other collective effects in the production of high brightness beams.
The workshop will be organized with four initial general review presentations, after which the
participants will divide in four working groups. Individual contributed presentations will be in the form
of poster papers, and the posters will be set up and available for discussion for the full duration of the
workshop. The advantage of this format is to provide maximum time for interactions between
participants. The working groups and initial talks are:
- Group 1: Single Particle Dynamics: recent advances in nonlinear dynamics, including frequency
analysis and mapping. Group Leader: R. Ruth (SLAC), Speaker: K. Oide (KEK)
- Group 2: Production and Dynamics of High Brightness Beams: advances in production,
acceleration, transport and monitoring of high brightness beams, including coherent and radiation effects.
Group Leader: R. Sheffield (LANL), Speaker: L. Serafini (U. Milan)
- Group 3: Beam Dynamics in Plasmas: advances in longitudinal and transverse dynamics, emittance
preservation and beam loading in plasma systems. Group Leader: F. Amiranoff (Ecole Polytech.),
Speaker: T. Katsouleas (USC)
- Group 4: Plasma Phenomena in Beams: transverse and longitudinal oscillations in high density
relativisitic beams, including parametric instabilities and filamentation. Group Leader: J. Wurtele (UCB),
Speaker: P. Colestock (Fermilab)
The workshop is sponsored by DOE, ENEA, ICFA, INFN, LBNL, SLAC, UCLA, KEK, U. of Rome "La
Sapienza."
The town in which the meeting will be held, Arcidosso, is a charming Tuscan town situated in the resort
area of Mt. Amiata. The citizens of Arcidosso are warm and welcoming. Arcidosso provides a most
congenial atmosphere for work and relaxation. We believe that you will thoroughly enjoy your stay in
Arcidosso and hope you will decide to join us for a most interesting workshop.
