Current success of the superconducting linear accelerators based on independently phased SC cavities gives a seriously reason to consider such structure in proton radiotherapy. Superconductivity allow to solve at once some problems concerned with a low rate of energy gain, high length, higher capacity losses and higher cost of the proton linear accelerator subsequently. One of the traditional aims of such facilities is receiving of the beam energy about 240 MeV with possibility of fluently regulation in range from 150 to 240 MeV that responds to irradiate the tumors located at different depth. The possibility of beam energy variation by means of RF field phase in last resonators and number of the resonator turn-off becomes the major advantage of the proton SC linac. The optimal choice of accelerator parameters and the beam dynamics simulation results with using BEAMDULAC-SCL code will presented*. Methods of the output energy variation with beam quality preservation in the proton SC linac will discussed.
