Scientists and experts of the Joint Institute for Nuclear Research (JINR), have helped to improve medical cyclotrons Belgian company IBA (Ion Beam Applications).
On Synchrocyclotron Laboratory of Nuclear Problems, Dubna accelerator first, and later reconstructed in Phasotron, with the 60-ies of the last century, at the initiative of prominent Russian physicist V. Dzhelepov (for many years he headed the laboratory, which now bears his name), in addition to basic research, work was started on proton therapy of cancer. Seven years ago, a Belgian company IBA, which has built in various parts of the world more than a dozen specialized medical proton cyclotron and was about to start production of medical carbon accelerators offered Dubna scientists and engineers to do a joint project of the superconducting medical cyclotron carbon C-400. To execute this order at JINR created the group, which included members of the two laboratories — nuclear issues and high energy physics. This group is led by Eugene Syresin in a short time with zero calculated accelerator of heavy nuclei of carbon and suggested elements of its design. Today, carbon cyclotron-400 begins constructed in France. In addition to this unique project, Dubna experts have proposed a number of improvements in serial medical cyclotron C-230, which produced IBA. Upgraded to JINR Belgian proton accelerator got its own name — the C-235, after which the company IBA has made a new proposal: to create a center for the JINR adjustment and launching medical proton accelerators. To this end, the Belgian partners have funded work on the equipment of the specialized areas in the 5th housing Laboratory of Nuclear Problems. It was here that works on setting up medical cyclotron for Russia’s first specialized proton therapy center in Dimitrovgrad, which should come into effect in 2014. In addition to this brand IBA cyclotron will stand and mark the JINR. Thanks made to the design of the cyclotron, which works in Orsay (France), the changes increased the efficiency and speed of the beam extraction with 50% (previous high) to 77%. Pmimo, specialists JINR also proposed to increase the helicity of the sectors of the cyclotron C-235, which would reduce the sensitivity of the cyclotron median plane distortion (which is, in fact, is the main cause of loss). When this change will also be made in the design of the accelerator, then the cyclotron will be even better.
