The next, XVII session of the Scientific Council on Low Energy Physics completed its work. It was chaired by JINR Vice-Director Professor Ch.Shimane. Professor Ts.Bonchev (Bulgaria), Doctors T.Fenesh and J.Ere (Hungary), Professor Nguyen Van Hieu (DRV), Doctor O.Zeliger (GDR), Professor J.Zhilich (Poland), Professor M.Petrashcu (Romania), as well as Directors of JINR Laboratories Academicians I.M.Frank and G.N.Flerov, Deputy Laboratory Directors Professor V.G.Soloviev, Doctors S.Chojnacki, K.Hennig and others took part in the session.

The main task of the session was to discuss the progress of the laboratories' topical plans on low energy physics and nuclear structure. Plans for international scientific cooperation, the results of the International Conference on Nuclear Physics in Munich, information from Dr. Chojnacki on the progress of development of the U-200 ion accelerator in Warsaw and others were also discussed.

The results of the third quarter were summed up at CEM. Head of the Centre for Economics and Mathematics M.A.Liberman, made a report. During this time, the production of three new electronic units was mastered and 30 rewinding tables were delivered to LHTA. Together with DLNP, research is carried out on the physical launch of the magnetic spark spectrometer; orders for the experimental section of the ringtron have been completed for the Department of New Acceleration Methods.

In February 1972, the JINR Evening School of Physics and Mathematics started its work. This year, the first 14 students graduated, most of whom entered Moscow State University, MEPhI, MIPT and other universities. It suggests that the level of training in physics and mathematics among graduates turned out to be very high. Directorate of the Institute provides great support to the School. The premises are provided by secondary school No.8. Significant assistance is provided by Head of the City Education Department N.V.Neganova, physics and mathematics teachers of city schools E.P.Mamaeva, T.V.Ivanova, G.V.Morozova and others.

For 20 years now, in Sector No.2 of the Scientific and Experimental Electronic Department of LHE, headed by M.N.Khachaturyan, the main instrument for physical research has been a Cherenkov total absorption spectrometer manufactured of lead glass. In 1958, this detector was used to measure the cross sections for the interaction of neutrons with protons, neutrons and nuclei and in 1963 - to measure the total and differential cross sections for the charge exchange of pions on protons. In 1966, a two-channel gamma spectrometer was used to study the electromagnetic decays of vector mesons. And finally, today, a 90-channel Cherenkov hodoscope has been developed in the Sector that among instruments of this kind is one of the best in the world in terms of its characteristics and will become one of the main detectors of the Foton experimental facility.

Staff members of the Sector hope that the Photon facility, once completed, will provide a number of interesting physical results.
