11:45 - 12:15 RNDr. Jiří BYSTRICKÝ (Centre d´études nucléaires, Saclay, France) Od matematiky k experimentální fyzice Summary My way from mathematics to experimental physic After graduating from Charles University, Prague, in mathematics, I seized the opportunity to work in the Join Institute of Nuclear Research in Dubna where I arrived with my wife in 1962. For physicists working at the Dubna accelerator, I carried out computations on the computer M20. My wife was employed as a laboratory assistant. My contribution treats some aspects of our life in the Soviet Union at that time – material conditions, travel possibilities, compilation of Russian-Czech dictionary of nuclear physics. My wife added some personal memories. Acquaintance with Dubna's physicists proved to be decisive for our further destiny. In 1969 František Lehar arranged for me an invitation to work in France and I definitely passed from mathematics to experimental physics. The L. Van Rossum's group where I was to work was situated for a few months at CERN in Geneva. The next experiment was scheduled in Russia at Serpuchov. Both Lehar and me participated on it only at Saclay by an analysis of measured data. At the end of my contribution, I describe briefly my further collaboration with F. Lehar, which resulted in a number of papers concerning nucleon-nucleon elastic scattering.
12:15 - 12:45 Prof. Ing. Ivan WILHELM, CSc. (Univerzita Karlova, Praha / Charles University, Prague) Ohlédnutí za spoluprací s SÚJV Dubna v neutronové fyzice Summary Some personal remarks on the Czechoslovak cooperation with JINR in neutron physics The paper is a short personal and so incomplete sight of the starting period of the building of the Laboratory of Neutron Physics (LNP) of JINR in Dubna. It describes its development in the period of first 15 years and the role of the Czechoslovak influence in this proces. The building of LNP, as one of the main units of the international scientific institution, was motivated by the headword – important center of research with neutrons, fully competitive in the world. The pulse fission reactor as a unique source of neutrons gave the chance to realize this mission. For this reason the main effort in the starting period was focused on the construction and installation of this equipment. The same attention was simultaneously given to the preparation of research programs based on the utilization of this device. Apart from the nuclear physics programs a chance to other research orientations of fundamental importance was given (from the point of view of nuclear physics, however, being considered as applications). The contribution of the Czechoslovak research community to the outlined process is described. The study of radiation capture in neutron nuclear resonances was initiated by Czechoslovak physicists and signified an important contribution to the physical research program of LNP in the initial period. The development of the alpha decay of neutron resonances studies was influenced by the Czechoslovak participation too. The intensive cooperation with Czechoslovak physicists in the neutron diffraction to the material research was realized in later period of time. A part of the paper is also dedicated to a description of the civil life at JINR in 1968 and the relationship of the institute representation to the political situation in the CSSR after the military intervention. A brief remark in the conclusion is dedicated to the pursuit of the Czechoslovak delegates of the rebuilding of the JINR after 1989 and in the last time period.
12:45 - 13:15 Ing. Milan ČIHÁK, CSc. (Ústav jaderné fyziky AV ČR, v. v. i., Řež / Nuclear Physics Institute CAS, Řež) Výstavba cyklotronu U-120M v SÚJV a jeho instalace v ÚJF ČSAV v Řeži Summary Construction of the cyclotron U-120M at JINR and its installation at the Nuclear Physics Institute CAS in Řež A history of the project of the principal reconstruction of the classical cyclotron U-120 to the isochronous U-120M will be presented. Cyclotron’s implementation at the JINR Department of New Accelerators in Dubna with the participation of Czech specialists, its subsequent installation at the Department of Accelerators of the NPI CAS in Řež and the following cooperation of both institutions during its operation and ongoing modernization will be shortly mentioned. The cyclotron U-120M manufactured in Dubna was originally intended to serve as a prototype for the reconstruction of U-120 cyclotrons in the former Soviet Union and associated countries. In the final stage, however, the NPI CAS in Řež remained the only candidate for the U-120M, where it was sold then in 1976. Due to its variability of accelerated particles (e. g. unique beam of 3He+2 ions) in a wide range of energies, relative reliability, the possibility of its maintenance and continuous modernization by a qualified staff, the U-120M cyclotron is still successfully operated. It is used both in basic research (including international co-operation) and applications and production of various radionuclides for commercial and non-commercial radiopharmaceuticals.

14:15 - 14:45 Ing. Jan BŐHM, CSc. (Fyzikální ústav AV ČR, v. v. i., Praha / Institute of Physics CAS, Prague) Ohlédnutí za účastí v experimentech SÚJV a CERN (od 60. let 20. století) Summary Looking back at my participation in experiments JINR and CERN (from the 1960s) The presented paper looks back at the fifty-year period of my cooperation with JINR and CERN, from the nuclear emulsions up to the discovery of the Higgs boson at LHC. I started my cooperation with the propane bubble chamber experiments at JINR (a three-year stay at JINR, 1966-68) and the 80cm hydrogen chamber DESY Hamburg on studies of (e+e−) generation by electrons in the electromagnetic field of nuclei. The antiproton interactions with protons at 5.7GeV/c were measured on pictures of the 2m hydrogen bubble chamber (CERN, a one-year contract as a visiting scientist, 1973) and at 22.4 GeV/c of the 2m bubble chamber Ludmila (JINR) installed at U70 in Serpuchov. Detailed attention is given to the international collaboration of six countries based on the 5m streamer chamber magnetic spectrometer RISK (JINR) placed in the magnet SP136 in the 38 GeV/c negative particle beam U70 in Serpuchov. From several suggested experiments two experiments developed in Prague/Bratislava (“Large PT” and “Production of dimions and J/ψ particles”) and one proposed by JINR/Berlin-Zeuthen (“Interactions of π, K and anti-p with nuclei”) were realized (a twelve-year stay at JINR starting from 1978, head of the sector RISK II). The results were awarded the 2nd prize of JINR, were presented at international conferences, published in 29 articles (40 quotations), and based on those results three candidate dissertations were defended at JINR and two diploma works at Charles University, Prague. After 1989, I joined experiments WA94 and WA97 at CERN (exploring features of quark gluon plasma) and ATLAS at LHC (a one-year contract at CERN in 1999).
14:45 - 15:15 RNDr. Alice VALKÁROVÁ, DrSc. (Matematicko-fyzikální fakulta UK, Praha / Faculty of Mathematics and Physics, Charles University, Prague) Ohlédnutí za spoluprací s SÚJV Dubna v subjaderné fyzice (1972−1983) Summary My contribution with JINR Dubna in subnuclear physics (1972–1983) In my contribution I present the history prior to my posting to the Joint Institute for Nuclear Research (JINR) in Dubna and my first experience with the life there. During the years 1973 – 1983 I participated in the evaluation of an experiment that studied the interactions of antiprotons with protons and then antideuterons with deuteron target in the two-meter hydrogen bubble chamber Ludmila. The chamber was placed in the beam of protons of the proton accelerator in the Protvino laboratory. In 1980 I defended my dissertation thesis that focused on this topic in Dubna. After my return to Prague I participated in the experiment RISK until 1986. This experiment studied interactions of pions with different targets and also associated production of J/ψ particle in the streamer chambre.
