A particle beam treatment system having a beam generation unit for generating a beam of charged particles, in particular ions, preferably protons, and having a beam guidance system. The generic beam guidance system takes up less space but can provide comparable or even improved beam properties because, in part, the beam guidance system seen in the direction of the beam of charged particles and behind the beam generation unit has at least one solenoid magnet as a beam shaping unit, and the at least one solenoid magnet of the beam guidance system is a superconducting solenoid magnet.
