Development, Testing and Commissioning of Powerful High Voltage Electron Accelerator | |
|
||
| A powerful high voltage electron accelerator has been designed for the use in installations for purifying of flue gases of thermal power plants (primarily, coal-fired electric power plants) from sulfur and nitrogen oxides. The design parameters of the accelerator are as follows: the energy is 1 MeV and the power is up to 500 kW in the continuous mode. A three-phase transformer-rectifier with a closed magnetic circuit operating at a frequency of 50 Hz is used as a high-voltage generator. The high-voltage generator and accelerating structure are located in a common high-pressure vessel filled with an insulating gas. Accelerated electron beam is scanned in a vacuum chamber of triangular shape and further is extracted into the atmosphere through an outlet window combined of four parallel sections measuring 60x2400 mm and covered with metal foil. The report presents the results of the development, testing of the accelerator on a NIIEFA testing facility and commissioning. | ||

| A C-80 cyclotron system is intended to produce proton beams with an energy ranging from 40 up to 80 MeV and current up to 200 mkA. The beams with these parameters will be used for commercial production of a wide spectrum of isotopes for medicine, proton radiation therapy of eye diseases and superficial oncologic diseases as well as for fundamental and applied researches. Manufacturing and installation of the cyclotron equipment and first section of the system for the beam transport to remote targets have been finished. Physical start-up of the cyclotron has been realized. In future, the C-80 cyclotron is supposed to be used as an injector of the C-230 synchrotron, which serves for additional acceleration of the extracted proton beam to energies of the order of 230 MeV. This will allow the Bragg's peak-based treatment procedures to be applied in the proton therapy of oncologic patients. | ||
| FRACH02 | High-voltage Accelerators Intended to Produce Continuous and Pulse Neutron Fluxes | 189 |
|
||
| Recently, in NIIEFA has been designed a series of high-voltage accelerators intended to produce continuous and pulse neutron fluxes with a yield from 10 to the tenth power to 10 to the twelwth power. The facilities designed can be used for operation in the continuous, microsecond and nanosecond modes, in any combination. In the pulse microsecond mode, ion currents of up to 100 mA with pulse lengths ranging from 2 up to 100 mks can be obtained on target. In the nanosecond mode, the accelerator allows an ion beam current of up to 5 mA with a pulse length in the range of 2-30 ns to be obtained. | ||

| FRACH03 | The CC1-3 Cyclotron System | 191 |
|
||
| A СС1-3 cyclotron system has been designed to be installed in the Vinca Institute of Nuclear Sciences, Belgrade, Serbia. This system will be operated in the laboratory of nuclear-physical methods of the elemental analysis. The system includes a compact cyclotron and a system for beam shaping with specified energy characteristics. The cyclotron ensures the acceleration of negative hydrogen ions up to energy in the range from 1 to 3 MeV and a beam of protons is extracted by stripping on a thin carbon foil. The beam-shaping system ensures the beam of protons with a spectrum width not more than 0.1%. The main unit of the beam-shaping system is a magnetic analyzer with a bending angle of 270 deg. To date, the equipment of the cyclotron system has been manufactured and tests have been carried out on test facilities in the D.V. Efremov Institute. Installation will be performed in 2012. | ||
