Dear Colleagues,

The date of the ICFA sponsored workshop (panel on advanced accelerators), to be held in Los Angeles at the UCLA Faculty Center, is November 9-12, 1999. The workshop is entitled "The Physics of High Brightness Beams." The date was chosen to be contiguous with the APS Division of Plasma Physics meeting the following week in Seattle, so that some attendees could coordinate their travel for both events.

This workshop can be seen as a successor to similar gatherings at UCLA and Indiana in 1995. The organizational effort is now underway at UCLA, chaired by myself and coordinated by Melinda Laraneta. We are now in the process of creating an exciting program for this workshop. To do this we are working with the following mission in mind: To explore the physics of high brightness particle beams, the methods used to describe and analyze physical effects in these systems, and the issues surrounding the creation, preservation, and diagnosis of such beams.

It is envisioned that the program will contain aspects of both high brightness electron, and heavy ion beam physics, in the hope that significant cross-fertilization of ideas will take place between the two communities working in these areas. It should include a wide-ranging set of issues to discuss, such as:

The plenary discussions will be limited to one and one-half days (6 talks each morning), so that there is an equal time for working groups, and a final half-day for summaries. We will have two review talks at the beginning to describe the applications which are driving the demand for high intensity, low emittance beams: one talk on electron beam-based physics (advanced accelerators, FELs, etc.) and one on heavy ion beam-based physics (accelerator transmutation of nuclear waste, thorium-cycle fission, etc.), so that the members of the electron and ion communities can understand each other's challengers.

 

The list of plenary speakers is as follows:

Marnix van der Wiel: "Applications of high brightness electron beams"

Patrick O'Shea: "RF photoinjector sources"

Bruce Carlsten: "Emittance growth processes in bends"

Luca Serafini: "Computational modeling of high brightness electron beam physics"

Dave Dowell: "Experimental methods for high brightness electron beam measurements"

Eric Esarey: "High brightness beam production and transport in plasmas"

William Barletta: "Applications of high brightness ion beams"

Thomas Wangler: "Halo formation in high intensity proton beams"

Robert Ryne: "Computational challenges in high intensity ion beam physics"

Martin Reiser: "Space charge effects in rings"

Allesandro Ruggiero: "Crystalline beams"

Sergei Nagaitsev: "Cooling of high intensity beams"

 

A preliminary breakdown of the working groups at this workshop is as follows:

  1. Space-charge effects in rectilinear motion: emittance compensation, pulse lengthening, halo formation, etc.
  2. Space-charge effects in bending systems: emittance growth in bends, compression physics, coherent radiation effects, etc.
  3. Exotic source physics: photon-assisted field emission, spin polarization, cathode-less (plasma) sources, etc.
  4. Experimental and technological issues: emittance and pulse length measurement, characterization of beam halos, accelerator and cathode development, etc.

The workshop proceedings will be published by World Scientific. Details of working group organization and publication will follow in a subsequent communication.
