>  The Committee understands that the present limitation in the
>  machine's luminosity is mainly due to a 1.3 GHz mode in the kickers
>  which forces the use of a working point in the tunes plane far from
>  the one foreseen as optimal by the calculations. The Committee is
>  therefore looking forward to the insertion of the new kickers,
>  which should be delivered to the Lab by the fall of 1999, as an
>  important step in achieving a substantial increase in  luminosity.
>  In the meanwhile the Committee endorses the proposal of the A.D. and
>  of the Directorate to rapidly set up a small committee of external
>  experts with the purpose of advising and helping the DAFNE crew
>  in the commissioning of the machine.
>  The Committee believes that, given the present situation, the best
>  running strategy is the following:
>
>   end Nov. -end Dec. 1999: Stable run at the best achivable luminosity
>             with the main goal of delivering at least 100 nb^-1/day to
KLOE.
>             At the same time  collisions in the DEAR i.r. should also be
>             tried, with the purpose of letting DEAR study background
>             conditions with interacting beams.
>             If it turns out that stable colliding beams cannot be obtained
in
>             both i.p. at the same time, two three-days periods should be
>             devoted to this studies, one at beginning and one at a later
time
>             towards the end of the running period.
>
>   Jan - end of Feb. 2000: Insertions of the new kickers. Start of the
>              installation of FINUDA, including installation of
>              the cryogenics lines, powering up of the magnet and
measurement
>              and mapping of the magnetic field.
>
>   March - July 2000: Resume of machine operations and colliding
>              beams for both KLOE and DEAR. The first two or three weeks of
>              this period should be devoted totally to machine studies,
>              while the remaining ones should be divided as follows:
>              three weeks of data taking for the experiments plus m.d.
>              and one week for continuing FINUDA installation as well
>              as for hardware interventions possibly needed by both
>              DAFNE and the other experiments.
>
>  By the end of April 2000, the Committee will decide to keep or correct
>  this plan, according to the performances achieved by the machine.
>
>  FINUDA
>  The Committee believes that today FINUDA is a well motivated community,
>  with many active young physicists fully devoted to the enterprise. The
>  status of preparation of the detectors is well advanced, for what
concerns
>  the silicon detectors, the drift chambers, the straw tubes and the
>  scintillation counters. Most of the work that could possibly be done
>  in the assembly hall, was done. The Committee believes that now FINUDA
>  should be allowed to install as soon as possible the detectors in their
>  final position inside the magnet in order to proceed with the final
alignment
>  and calibration.
>  With a complete detector they will also be able to progress in the
testing
>  of the electronics and the data acquisition system; the collection of
>  cosmic ray data will allow them to check more thoroughly the
reconstruction
>  programmes, the detector performance and the simulation software.
>  At the next meeting, the Committee would like to see a clear assessment
>  by FINUDA about the physics potentials that can be achieved in the case
>  they can collect 5 and 50 pb^-1.
