The frontiers of beam research point to ever higher energy, higher brightness, lower emittance (or lower temperature) beams with ever increasing particle species. These demands in turn have triggered a rapidly increasing number of beam phenomena that involve quantum effects. Concurrently, the violent accelerations which are becoming available through novel accelerator research may, perhaps, help to investigate fundamental physics associated with general relativity. In a different aspect, certain mathematical formulations developed in quantum mechanics and quantum field theory have been applied to describe beam phenomena, although those phenomena do not necessarily involve the Planck constant. With these exciting developments in mind and the important role they may potentially play in the next century, it should be timely to organize such a workshop dedicated entirely to the quantum aspects of beam physics.

As the very first workshop on such a subject, the program will be blended with a reasonable amount of pedagogical lectures. The topics of lectures/working groups include,
1. Quantum Fluctuations in Beam Dynamics: synchrotron radiation and spin polarization in storage rings, spontaneous/stimulated emissions in FELs, radiation reaction in focusing systems, etc.
2. Photon-Electron Interaction in Beam Production, Cooling, Monitoring: laser cooling, Compton backscattering, Shintake monitor, laser wire, quantum efficiency in photocathodes, etc.
3. Beam Phenomena under Strong EM Fields: beamstrahlung, coherent pair creation, minijets, crystal channeling, nonlinear QED effects in heavy ion collisions, etc.
4. Production and Handling of Condensate Beams: production and handling of Bose-Einstein Condensate atomic beams, crystalization/Fermi liquidation of ion, proton, and electron beams, ultimate limit of low emittance photon beams, etc.
5. Foundamental Physics under Violent Acceleration: laboratory tests of general relativity, Unruh effect, and dynamic Casmir effect, etc; accelerator production of gravitational waves and gravitons.
6. Quantum Methodology in Beam Physics: uses of renormalization theory, supersymmetry, Wigner function, Schrodinger equation, Dirac equation, etc, in beam physics.
Depending on the eventual response from our colleagues attending the meeting, certain topics listed above may be organized into joint working groups. A tentative plan of the working groups and their convenors are as follows:
Group A (Topic 1): K. J. Kim* and K. Oide*,
Group B (Topics 2&4;): S. Chattopadhay and another name to be identified,
Group C (Topics3&5;): K. Yokoya and A. Mellisinos,
Group D (Topic 6): A. Dragt.
* To be confirmed
A tentative list of plenary talks are given below for your information.
