Wobec mijającego czasu i zmieniających się sytuacji geopolitycznych trwanie jest czymś niezwykłym, a jubileusze służą jako przystanki, by spojrzeć wstecz i w przyszłość. 60 lat działalności Instytutu Fizyki Jądrowej daje wiele powodów do dumy z jego osiągnięć i do radości z szerokich perspektyw na przyszłość. Warto co dekadę zatrzymać się, by dokonać podsumowań, zweryfikować plany i przyjrzeć się jak jesteśmy postrzegani w kraju i na świecie.

To the passing of time and the changing geopolitical situation the duration is something unusual, and anniversaries let us to look back and to the future. 60 years of activity of the Institute of Nuclear Physics gives us many reasons to be proud of its achievements and to rejoice with its broad prospects for the future. Worth every decade to make summaries, verify the plans and look at how we are perceived in the country and the world.

The operation of the Warsaw heavy ion cyclotron is presented. Technical solutions adopted were intended to accommodate the needs of different groups of users requiring a wide scope of beam species and energies. The accelerating structure of the machine, with two 45 degree dees, allows for the operation in the harmonics modes from 2 to 6 (first harmonic mode is also possible, although the acceleration of protons and deuterons is currently not within the scope of interest). Available energies range from 2 to about 10 MeV/amu due to the wide range of the stripping extraction system. Development of the multiturn stripping extraction technique was necessary to achieve the flexibility in energy variation, otherwise not reachable due to the highly saturated iron structure, which makes impossible the change of magnetic field and radio-frequency within the desirable limits. At present, the cyclotron, equipped with the ECR ion source, is capable of delivering ion beams from gaseous media up to Ar. Available ion beam species, their energies and intensities obtained up-to-date are shown. An overview of the experiments performed on the Warsaw cyclotron, including basic nuclear physics research, solid state physics and materials science, is intended to demonstrate the potential of the facility. The efficiency of the cyclotron and the ion beam line optics is discussed, as well as the plans for the future upgrade of the cyclotron and its infrastructure.

Ion beams are unique tools in modern science and technology. They are used for the analysis and modification of materials and are applied in medicine and technology. In cancer therapy fast protons allow a precise tailoring of the radiation field to the tumour, thus maximising the tumour control probability and simultaneously reducing the risk of side effects. Modification of the structure of solids by ion irradiation results in local structures on nano-scale, e.g. high-tech filters having defined pore numbers and pore sizes are produced by high-energy heavy ion irradiation with consecutive etching. Electronic devices utilised in areas with high radiation level have to be tested for their radiation hardness. The devices are irradiated with accelerated ions to receive the same dose by high-energy ions as expected during their lifetime. For materials sciences the analysis of composition and structure of solids is of uppermost importance. Complex layered structures are analysed by ERDA (Elastic Recoil Detection Analysis). Investigation of art and archaeological objects has to be non-destructive. PIXE (Proton Induced X-ray Emission) allows elemental analysis without sampling of the object. Different applications of high energy ions will be presented.

Content available Status report of the VINCY Cyclotron
EN
The VINCY Cyclotron is the main part of the TESLA Accelerator Installation. The diameter of the pole of this machine is 2000 mm. Its bending constant is 145 MeV while its focusing constant is 75 MeV. The radiofrequency system of the machine consists of two l/4-resonators with the eigenfrequency in the range from 17 to 31 MHz. Ions coming from a heavy ion source or a light ion source will be injected into the machine axially. They will be introduced into its median plane by a spiral inflector. Heavy ions accelerated in the machine will be extracted from it by a foil stripping system or by an electrostatic deflection system. Light ions will be extracted from it by the foil stripping system. The first programs of use of the VINCY Cyclotron are related to routine and experimental production of radioisotopes and radiopharmaceuticals, and to biomedical research with ion beams. The first beam extracted from the machine will be the proton beam of the energy of 22 MeV obtained from the H2+ beam extracted from the light ion source. This beam will be used first for production of radioisotope 18F and radio-pharmaceutical 18FDG, to be employed for positron emission tomography
