“…Making use of beams of different bombarding particles -protons, neutrons, and heavy ions, the ISOL installations at present provide the production of considerably more than 2000 mass-separated isotopes of almost all elements of the periodic system. The on-line mass-separator facilities like ISOLDE (CERN, Switzerland) [6], ISAC (Isotope Separation and ACceleration, TRIUMF, Canada) [7], IRIS (Investigations of Radioactive Isotopes on Synchrocyclotron, PNPI, Gatchina) [8] and many others enabled the production of radioactive isotopes with half-lives from several milliseconds to several thousand years which are used for studying in nuclear physics, solid-state physics, and for some medical physics experiments. The first experiments on receiving mass-separated medical radionuclides for tests on animals [9,10] were made at the ISOLDE installation which is used in general for nuclear physics research.…”

a cyclotron C-80 designed to produce protons with the energy of 40-80 MeV and beam intensity of 100 μA (first stage) has been launched. One of the beams of the cyclotron will be used for the treatment of malignant eye tumors. At the same time the main goal of C-80 is the production of a wide range of medical radionuclides for diagnostics and therapy. For this purpose, the construction of the RIC-80 (Radioactive Isotopes on the C-80 cyclotron) complex intended to function on the C-80 beam has been planned. A brief description of the RIC-80 complex is given, and the results of the use of new methods and studies of target devices for the production of radionuclide generator 212 Pb/ 212 Bi and 223 Ra, 224 Ra, 225 Ac radioisotopes that undergo alpha-decay are discussed. The suggestions of the mass-separator use in the on-line and semi on-line mode to obtain high isotopic purity radionuclides, which is especially important for medical applications, are discussed. The results of a new hightemperature method use of lutetium radionuclide separation from the ytterbium target material in a high vacuum are presented.

“…The main problem -the extraction and isotopic separation produced radio nuclides is under successful solution for almost 50 years already by means of ISOL installations at beams of different bombarding particles -protons, neutrons and heavy ions. Such on-line systems like ISOLDE (CERN, Switzerland), ISAC (TRIUMF, Canada), IRIS (PNPI, Gatchina) [2,3,4] operation on-line at proton beams, allows to obtain at present more than 2000 separated isotopes of almost all elements of the Periodic system. Produced radioactive isotopes with half-life from several milliseconds to several thousand years are used in nuclear physics study, in study of solid state physics and in the radiation medicine.…”

Abstract. Presently, the cyclotrons are playing a very important role in the production of radionuclides for medicine, which are very safe and reliable installations. From radioisotopes produced with cyclotrons, it is rather easy to select one that has appropriate nuclear-physical characteristics for medical use, in comparison to the ones produced with reactors. At PNPI, a high current cyclotron C-80 with the energy of extracted proton beam of 40-80 MeV and the current up to 200 µA is under construction. One of the main goals of C-80 is the production of a wide spectrum of medical radionuclides for diagnostics and therapy. At present time, a project is worked out for the construction of radioisotope complex RIC-80 (Radioisotopes at the cyclotron C-80) at the beam of C-80. In the presented submission, the project of RIC-80 complex is discussed, which includes three target stations for the production of a large set of radionuclides for medicine. The peculiarity of the proposed radioisotope facility is the use of the mass-separator with the target-ion source device as one of the target stations for on-line, or semi on-line production of a high purity separated radioisotopes. The first results on the target development for production of different medical radionuclides, including radioisotope generator for PET diagnostics 82 Sr, are presented as well.

“…Based on radiative heat transfer studies, Zhang and Alton [4] have proposed porous and fibrous composite targets, that are expected to operate with deposited beam powers of up to 40 kW. Besides, upon testing with both resistive and electron-beam heating, the TRIUMF-ISAC high-power target equipped with a finned container was shown to be capable of dissipating more than 25 kW when operated at 2200 1C [5]. However, these different studies concern solid targets, and characterized by relatively low thicknesses.…”

a b s t r a c tIn the context of the forthcoming next generation of Radioactive Ion Beams (RIBs) facilities based on an Isotope Separation On Line (ISOL) method, the development of production targets capable of dissipating the high power deposited by the primary beam is a major challenge. The concept of a high-power target based on a liquid Pb-Bi loop incorporating a heat-exchanger and a diffusion chamber was proposed within EURISOL DS and is being developed within the LIEBE 1 project. Due to the non-static character of the target, specific hydrodynamics issues are of concern. In this paper, these issues are studied mostly based on three-dimensional (3D) Computational Fluid Dynamics analysis of the flow of the Lead Bismuth Eutectic (LBE) target, resulting in optimized designs. The concept and hydrodynamic challenges of generating RIBs from a liquid-metal-loop target irradiated with a high-power primary beam are presented. The optimization of the target design has been conducted keeping in mind the need for a fast and efficient release of short-lived isotopes. This study shows that approximately 100 ms after the proton pulse the irradiated liquid-metal is entirely and uniformly evacuated from the irradiation volume and spread in a shower of small droplets (100-μm radii), in order to reduce the diffusion length of isotopes. Solutions to deal with the typical cavitation risk due to the presence of low-pressure zones in the liquid have also been found and simulated.
