　　REPORTS
　　General report by Director
- On 27 November 1999, a seminar for public people was held at RCNP, and many public people
visited the RCNP accelerator facility, and got information on the K400ring-cyclotron and 
the experimental devices.
- TARN�U workshop was held on December 13-14. RCNP staff Meeting was held on 
December 24. It was decided that RCNP will not request to move the TARN�U facility 
from KEK.
- People from Ibaraki city office visited RCNP on December 28.


　　- An ECR ion source of the SF cyclotron will be transferred from CNS to RCNP.
　　- RCNP review was held on January 5-6.
　　- Personal affairs:
　H.Suganuma will move to Tokyo Institute of Technology.
　M.Nomachi moved to Osaka University.
　　- Calls for positions:
　Visiting Seminar Researcher (closed on January 10)
　COE (Closed on February 7)
　Researcher (closed on February 24)
　An associate professor position for the theory group is now called.
　　- BPAC was held on February 29.

Reports from each group in RCNP
- Nuclear Science 1A
Activities at RCNP Ring Cyclotron Facility were reported.
M.Yosoi (Kyoto U.) reported on the activities of Kyoto group, including the (p,2p) and (p,p’) reactions.
T.Wakasa (RCNP) reported on the status of construction of the new WS beam course.
M.Fujiwara (RCNP) reported on the (3He,t) measurement on 176Yb and discussed about the new 
project LENS related to the solar neutrino problem.
T.Shimoda (Osaka U.) reported on the results of new development for studying the “snow ball” 
production in the low-temperature He liquid.
K.Hatanaka (RCNP) reported on other activities.

- Nuclear Science 1B
T.Nakano (RCNP) reported on the present status of LEPS at SPring-8.
A beam intensity of 5×106 photon/s was achieved. The beam energy resolution of the LEPS 
spectrometer system was estimated to be 15 MeV.
Experiment to measure φ photo-production will start soon.

　- Nuclear Science 1C
K.Takahisa (RCNP) reported on the present status of the Oto Cosmo Observatory,


including the Dark matter measurement.
Y.Nagai (RCNP) reported a study on 4He photo-disintegration at ETL.
　
　- Theory
H.Toki (RCNP) reported on the activities of the theory group of RCNP.
The international conference “Confinement 2000” was finished successfully.

　- Accelerator
S.Ninomiya (RCNP) reported on the upgrade of the AVF cyclotron. The magnetic field of
AVF cyclotron will be greatly stabilized by improving the water cooling system.
There is a possibility that we can try achieve the single turn extraction after the stabilization
of the magnetic field. A new model of the D-electrode is under development.

- Computer
M.Nomachi (Osaka U./RCNP) reported on the status of the computer system.
A software bug was found in the migration system of the RCNP UNIX system.
Upgrade of the computer system is scheduled in this calendar year. The collaboration with
the computer center of Osaka University for the super-computer will continue.

DISCUSSIONS
FY2000 funding status
- Report by Director Y.Nagai
The director reported on the budget requests for FY2000 as follows:
　1. Returning staff position to Yamagata University and Kyoto University.
　2. Starting a group to support the operation of LEPS at SPring-8.
　3. Upgrade of the AVF cyclotoron.
- Short discussion was made on the budget request.

Future plan and new projects
- Ultra Cold Neutron (UCN) source
　The director reported that RCNP approved the UCN project after the confirmation of
　the validity of the new method of the UCN production with the condition that the main budget 
　for the project should be available from the outside. There was a question about the condition 
　of the approvement. The committee discussed on the possibility of the budgetary support from
　RCNP. The decision was postponed until the result of the great application will be clear.

　- Nuclear Theory Lecture series
　H.Toki (RCNP) proposed to start a lecture series, Nuclear Theory Lecture.
　The frequency of the lecture will be one lecture/month, and travel and local expenses
　for participants (young researchers) will be supported. The proposal was generally approved,
　and H.Toki, S.Hirenzaki (Nara Woman’s U.), T.Watabe (RCNP) and T.Sato (Osaka U.) will 
　work for starting the lecture series.

　RCNP workshop
　　- GR2000
　　　M.Fujiwara (RCNP) requested budget support for the international conference GR2000
　　　(June 12-15, 2000). The request was approved by PPAC and sent to Director.
　　- LEPS2000
　　　H.Shimizu (RCNP) requested budget support for the international workshop LEPS2000
　　　to be held as a pre-symposium of SPIN2000. The request was approved by PPAC 
　　　and sent to Director.

　　Others
　　- Director reported the status of discussion on the possible change of the management system
　　　of Osaka University. The committee discussed on the relation between the change of
　　　the management system and the future prospect of RCNP.

　　　The next PPAC meeting will be held on July 17(Mon), 2000.
