Japan-Italy Symposium
on Beam Physics related to
High Luminosity Meson Factories

Frascati, 16 and 17 December 1999

at Laboratori Nazionali di Frascati of
Istituto Nazionale di Fisica Nucleare (LNF-INFN)



         DAFNE and KEKB are now completed and are under operation. These two accelerators are similar to each other: they have two rings with high currents, many bunches, crossing angles for the beam-beam collisions etc.

         In constructing these machines, physicists in Italy and Japan have collaborated with friendship. For the future of the high energy accelerators in both countries, it is time to start more regular collaboration.

         The symposium is devoted to:

1) review of the performance of the present accelerators;
2) common problems and their possible cures;
3) ideas to go beyond the design luminosity;
4) ideas and beam dynamics challenges for further luminosity.

         The topics will be limited mainly to beam dynamics problems and technical issues will not be covered fully, unless strongly related to dynamical issues.
