  In 2009 IBA decided to start the development of a compact superconducting synchrocyclotron as a proton-source for the small footprint proton therapy system called Proteus One ®. The cyclotron has been completely designed and constructed and is currently under commissioning at the IBA factory. Its design and commissioning results will be presented.

  At IBA, the steels used to build the magnets of the Cyclone 230 are cast on demand, using very strict criteria, casting procedure, requirements and quality control. Among the various steps performed at the foundry, a thermal annealing is made. In this work, we assess the usefulness of such thermal treatment. In this communication, samples of pure iron cast ingots (maximum concentration of C = 31 ppm, N = 94 ppm, O = 31 ppm, S = 65 ppm) have been magnetically and structurally characterized. Progressive magnetic softening was observed upon successive annealing steps. These changes of the magnetic properties were ascribed to the relief of internal stresses. Various results, obtained by means of X-ray diffraction, electron microscope and precise determination of magnetization curve and hysteresis loop, will be presented and commented.
