THCAMH05 | The CC-18/9M Cyclotron System for Production of Isotopes for PET | 117 |
|
||
The CC-18/9M cyclotron system has been designed, manufactured and delivered to JSC "NIITFA", Moscow to be operated in a pilot PET center. Acceptance tests have been conducted; design parameters of the updated cyclotron have been obtained: energy variation of accelerated proton and deuteron beams within the ranges of 12 - 18 and 6 - 9 MeV with currents of 150 and 50 mkA respectively. For the first time in NIIEFA practice the cyclotron is equipped with a target system intended for the production of F-18 and C-11 radionuclides for PET. At present the cyclotron system in the PET center is put into commercial operation. | ||

TUCASH04 | Physical Start-up of the C-80 Isochronous Cyclotron | 179 |
|
||
Works on the creation of a cyclotron for the acceleration of H− ions at energies ranging from 40 up to 80 MeV have been carried out over a number of years in PNPI, the National Research Centre Kurchatov Institute. The cyclotron is intended for production of a wide assortment of radioisotopes for medicine including radiation generators (Sr-Rb, Ge-Ga), proton therapy of ophthalmic diseases, tests of radioelectronic components for radiation resistance, studies in the field of nuclear physics and radiation material science. In June, 2016 physical start-up of the cyclotron was realized in the pulsed mode; the beam of ~10 mkA was obtained at the inner probe, the extracted beam at the first diagnostic device was ~8 mkA and ~7.5 mkA at the final diagnostic device of the beamline. In the near future we plan to obtain the design intensity of 100 mkA. | ||

TUCASH05 | The CC1-3 Cyclotron System. Installation and Test Results | 182 |
|
||
A unique CC1-3 cyclotron system has been installed in the Vinca Institute of Nuclear Sciences, Belgrade, Serbia to be used in the laboratory of nuclear-physical methods of the elemental analysis A compact cyclotron and a beam shaping system ensure an accelerated proton beam in a wide range of energies from 1 to 3 MeV with a spectrum width not more than 0.1%. Tests of the cyclotron system have been carried out at proton energies of 1.0, 1.7 and 3 MeV with the beam transport to the final diagnostic device. | ||

Preparation of the Water Target Device Experience for the F-18 Operating on the Cyclotron CC-18/9M | |
|
||
Experience of preparation of the water target device for the F-18 operating is presented in the present article. Processes of vacuum preparation, target coils, seals, a body of a target, deinstallation and installation of the target device are considered. So, by preparation for mounting of vacuum and target coils, as a result of flushing in a hostile environment (potassium permanganate) the material corrupting discloses at a stage of the vacuum target tests is revealed. Subsequently coil flushing was carried out in the deionized water. The derived development researches have revealed a need for refuse a hostile environment by preparation of target devices. Isotope operating results and the subsequent product synthesis based on F-18 showed an almost total impurity absence. The product yield after the module of synthesis constituted at least 60%. Besides, installation works with the target device has shown need of application of quick-detachable connections on the cooling target lines that generally affined with the high induced activity on the work place. | ||

WEPSB061 | Neutron Generators of the NG-10 Series for Metrology | 502 |
|
||
Neutron generators NG-10 and NG-10M with a neutron yield of 1*1010 n/s and 2*1011 n/s respectively have been designed in the JSC "NIIEFA". The generators are high-voltage accelerators with target devices intended for installation and effective cooling of Ti-T/Ti-D targets of different diameters. A duoplasmotron with a beam current up to 5 mA is used in the NG-10 generator, and the NG-10M employs a microwave ion source providing the beam current up to 10 mA. The power supplies, which are under high voltage, are controlled via fiber optic communication lines. Deuterium ions produced in the ion source are accelerated up to 150 keV in a sectionalized accelerating tube, separated in mass with an electromagnetic mass-separator and focused onto a target with a doublet of electromagnetic quadrupole lenses. The generators are equipped with several lines to transport the beam to targets, which can be placed in separate rooms. In addition to a high and stable in time yield of neutrons when operating continuously, the generators provide the pulsed mode with a smooth variation of the pulse width from 2 mks up to 100 mks and pulse repetition rate from 1 Hz up to 20 kHz. | ||
