title: [Production and study of therapeutic proton beams on the remodeled phasotron].
abstract: The first results of the formation and transportation of therapeutic proton beams at the JINR phasotron are presented. To ensure flat-top depth-dose distributions with a steep back slope, a method of forming a beam with a necessary energy spectrum from a non-monoenergic beam is employed. Extension of the flat hop of depth-dose distribution is 4.7 g/cm2 for a proton beam with the mean energy of 200 MeV.
