Khaibullin³ ¹Federal State Unitary Enterprise Moscow Radio Technical Institute, Moscow, Russia ²Lomonosov Moscow State University, Moscow, Russia ³Alikhanov Institute for Theoretical and Experimental Physics, Moscow, Russia Abstract Investigations in hadron therapy having been carried out since 1953 proved its efficiency in treatment of oncological diseases and made it possible to be applicated in clinical practice (since 1990). 16 hospital based proton therapy facilities (PTF) function and 15 ones are currently under construction worldwide. Before 1990 Russia was one of the leading countries in development of proton therapy. But due to political and economical cataclysms in 1990s became behind other countries in radiation therapy application and in proton therapy particularly. Just in 2005 the Moscow mayor made a decision to construct the first Russian PTF based on the Botkin Hospital (for the second time, the first was in 1997, some months before the default in Russia). The project of this PTF describing briefly in the report is currently undergoing the appraisal in Moscow Committee of the State Project Appraisal. ª – corresponding author |

Yu. Budanovª, O. Belyaev, I. Zvonarev, A. Maltsev, E. Mazurov, S. Strekalovskyh, V. Teplyakov Institute of High Energy Physics, Protvino, Russia Abstract Advantage of use of the accelerated ions to the medical purposes has been proved in the middle of the last century. However, only recently this idea began to be used widely in applied medicine. It became possible owing to qualitative development of accelerating technique. An essential role in invention and a practical realization of acceleration and focussing of ions in systems with high-frequency quadrupole focussing (RFQ) here has played. In IHEP first-ever such accelerator has been implemented, and then some more various accelerators with RFQ [1] have been produced. RFQ application as an initial part of the accelerator now is applied in the in most cases of accelerators of ions to the medical purposes all over the world. In IHEP accelerators with drift tubes and simultaneous use of high-frequency focusing RFQ DTL also are developed and put into operation. Application RFQ DTL is practically realized for acceleration of protons up to 30 MeV [2]. Now in IHEP working on creation of two accelerators with use RFQ for the medical purposes are carried out. In the report theoretical calculations, sketches and design decisions for projects of these accelerators are submitted. The accelerator of carbon ions up to energy 286 keV/u is intended for injection of carbon ions in existing accelerator I-100 according to medical ion IHEP program. This accelerator will represent section RFQ with application of a special structure of electrodes and radio engineering division into two subsections, providing work of second subsection RFQ as debuncher. Other accelerator for protons with energy 5 MeV is planned as injector in the ring accelerator for the center of proton-beam therapy of Botkin's hospital (Moscow). The accelerator will consist of two sections, in first section is used conventional RFQ, in the second section the RFQ DTL structure is applied. Sections are planed on the basis of resonators with a longitudinal magnetic field. ª – corresponding author |

Shtarklev Budker Institute of Nuclear Physics Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Russia Abstract A new irradiation line based on ILU-6 electron accelerator is put into work in September 2007. The line is purposed for decontamination of medicinal raw and sterilization of the medical goods. The medicinal raw is treated in hermetically sealed polymer packs. The products are transported to the irradiation zone and back from it by the loop conveyor driven by chain. The nominal electron energy is 2.5 MeV, conveyor velocity – up to 10 cm/s, production rate – up to 400 kg/hour. The installation is housed in specially designed 2-storeyed building. The biological shield is made of concrete. The report describes ILU type industrial electron accelerators. It describes their main parameters, design, principle of action, electron beam extraction devices, wide set of auxiliary equipment for various technological processes and ways of their usage. ª – corresponding author |

Onischenko Joint Institute for Nuclear Research, Dubna, Russia Abstract Dubna scientific medicine center is under development since 1967 on the base of the proton beam of LNP JINR Phazotron. Proton beam with energy Åð~170 MeV and intensity I~0.1 μA is used for patients irradiation. Proposal of the cyclotron with the same beam characteristics was reported earlier at the RUPAC04 [1], ICAA05 [2], RUPAC06 [3] and printed in magazine [4]. New project of C250 – cyclotron for proton therapy is considered in this paper. Energy of the extracted beam increased according to last medical requirements up to 250 MeV. 4-fold and compact types of magnet yoke were studied by 3D computer magnetic field calculations. The ability of optimal combination of the magnet yoke, HF and extraction systems of the cyclotron taking into account the dynamics of the proton beam in calculated magnetic and accelerating field is under discussion. ª – corresponding author |

THE PROJECT OF RFQ LINAC FOR AN EDUCATIONAL LABORATORY AT RAC OF MEPHI |
|
|
B.Yu. Bogdanovich, V.V. Kapinª, A.V. Nesterovich Moscow Engineering Physics Institute (State University), Moscow, Russia Abstract RFQ linac of light ions with the energy up to 2-MeV/amu and the charge-to-mass ratio ≤1/3 is proposed at the Radiation-Acceleration Center (RAC) of Moscow-Engineering Physics Institute (MEPhI). The accelerator is intended for educational and research purposes. In the report, RFQ designs with two different frequencies of 150 MHz and 433 MHz are considered as possible candidates. Two types of the RFQ designs using either a constant or an increasing intervane-voltage distribution along the structures are compared and discussed. The former type is a conventional RFQ, and the latter type allowing an in-creased energy gain results in a shorter accelerating struc-ture, while it requires a higher RF power. ª – corresponding author |
