Adaptation of AIC 144 cyclotron to the radiotherapy of eye melanoma

This article was devote to the adaptation of cyclotron AIC 144 to the radiotherapy of eye melanoma. First part described the optimization of energy and shapes the protons beam, which was made by the specialist from Joint Institute Nuclear Research in Dubna. The result of they work, was successful the energy of proton increased to 59 MeV and shape of the beam decreased. Second part described the renovation of ratio frequency generator. In order to improve the conductivity, all electrical connection was welded. (author)
