The cyclotron produces a beam with an energy of 250 MeV, which can be reduced by a degrader to a minimum of 70 MeV. The gantry beamline begins at the coupling point and offers a full 360 rotation. To reduce the momentum spread of the beam, an ESS with a variable-thickness wedge is employed. The thickness of the wedge can be adjusted based on the beam's energy. Scanning magnets are utilized to scan the beam and administer the dose to the entire tumour. Patient treatment takes place at the isocentre. Q1Q14 are quadrupole magnets and D1D4 are dipole magnets.
