THB02	Production of 70 MeV Proton Beam in a Superconducting Cyclotron	294
	V.L. Smirnov, S.B. Vorozhtsov JINR, Dubna, Moscow Region, Russia
	Production of 70 MeV proton beams with help of a cyclotron-type facility is one of highly requested tasks presently. Such beams are used for medical applications including direct tumor irradiation and also for production of medical isotopes. The applications mentioned above dictate corresponding requirements imposed on the beam quality and intensity. For proton therapy treatment it is sufficient to have 300-600 nA output beam current with rather strict tolerance on the transverse beam quality. On the other hand, for the isotope production the major requirement is high enough beam intensity (hundreds µA) with less demanding beam quality. Nowadays, for production of the proton beams in the energy range considered cyclotrons with resistive coil weighting ~200 tons are mostly used. In these cyclotrons two extraction methods - with electrostatic deflector and with stripping foils - can provide somewhat different quality of the output beam. In given report a possibility of using a superconducting cyclotron instead of room-temperature one is considered. To this end, acceleration of various ions was investigated with analysis of the main facility parameters and resulting output beams.
