Workshop on Very Rapid Cycling Acceleration
with FFAG Synchrotrons

KEK, Tsukuba
December 6-8,1999

We are pleased to announce the workshop on very rapid cycling beam acceleration with FFAG(Fixed Field Alternating Gradient)synchrotrons, its present understandings and future perspectives. The purposes of the workshop are

1)to discuss its directions such as a proton driver for a muon collider, an accelerator driven system for nuclear energy, etc
2)to discuss its direction such as a very rapid cycling acceleration for muon phase rotation and acceleration
3) to establish design principles with modern accelerator technology such as a high gradient accelerating cavity, and
4) to study beams under extreme regime such as a high repetition and high intensity operation in highly nonlinear magnetic field.


The topics to be covered include
- proton driver, and spallation neutron sources for material sciences and accelerator driven system for nuclear energy such as a high current machine,
- accelerator at industrial scene including medical use with its very stable operation,
- energy breeder with its extreme high power efficiency,
- muon acceleration and storage ring, and neutrino factory as a versatile beam transport,

for 1)
- lattice design principle with modern concept for scaling and non-scaling FFAG
-computational tools to track particles in a small machine,
- operational scenario aiming high current,
- pursuit of high power efficiency,
- a high gradient accelerating cavity,
- other necessary hardware R&D,

for 2)
- possible scheme for muon phase rotation,
- feasibility and problems for muon acceleration,

for 3) and 4),
- development of very high field gradient RF cavity,
- dynamic aperture.
