Operation regime of AIC-144 cyclotron for delivering 60 mev proton beam to the radiotherapy of eye melanoma

Abstract

The latest computational and experimental results concerning 60 MeV proton beam acceleration and extraction in AIC-144 cyclotron of the Institute of Nuclear Physics (Krakow, Poland) are being considered. Improvement of RF system reliability at dee voltage of 60 kV and frequency of 26.26 MHz as well as precise shaping of the cyclotron magnetic field made it possible to accelerate the proton beam up to 60.5 MeV and to provide its extraction with overall efficiency ~35%. The beam is planned to be used for the long-term radiotherapy of eye melanoma in the year 2013.
