[en] The Data Centre of the Leningrad Institute of Nuclear Physics (LIYaF) is working on the establishment of a library of problem-oriented computer programs for solving problems of atomic and nuclear physics. This paper lists and describes briefly the programs presently available to the Data Centre. The descriptions include the program code numbers, the program language, the translator for which the program is designed, and the program scope

[en] The basic trends in the activity of the Data Centre of the Leningrad Institute of Nuclear Physics (LINP) are considered. The LINP Data Centre is involved in compiling handbooks on the properties of nuclear excited states; it publishes its own bulletin and descriptions of calculation programs for nuclear models. The information-retrieval system of the LINP Data Centre is based on the M-4030 and ES-1010 computers and permits to retriev abstracts by key words and inquire for actual data on the properties of nuclear states

[en] A number of different techniques have been developed over the years to obtain ultracold neutron beams of sufficient intensity to enable exploitation of the special qualities of these particles in experiments where either the basic properties of the neutron itself are investigated or where they serve as sensitive tools in high-resolution condensed matter research. Ultracold neutron sources available at present (1989) are stronger by 10⁴ to 10⁷ times than the first installations were 20 years ago. It may be expected that this trend will continue in the foreseeable future. We shall attempt to set up general criteria for estimating the efficiencies or the potential of the various methods of UCN production in their interrelation with the different schemes of primary and cold neutron sources in existence or under discussion at present.

[en] The research reactor is now under construction at the Leningrad Institute of Nuclear Physics, 45 km away from the city. The projected power of the reactor is 100 Mwt. The reactor will be used for physical investigations with external neutron beams. The thermal neutron flux in the reflector is higher than 10¹⁵ neutrons/cm² sec and the flux in the usual water trap in the centre of the core is 4.10¹⁵ neutrons/cm² sec. Sources of cold and fast neutrons are designed in the reactor. Most of the experiments will be conducted on stationary neutron guides. (author)

[en] Absolute dose calibration of three medical proton beams (JINR, ITEP and LINP synchrotrons) are compared. Measurements of absorbed dose values of ITEP and LINP beams were performed by means of LiF and CaF² thermoluminescent dosemeters, that had been perliminary calibrate at JINR medical proton beam. The accuracy of comparative dosimetry in each series of measurements were 10-12% (standard deviation). Absolute dose values of every beam are in agreement within the measurement accuracy in spite of the differences of energy and time parameters of the beams
