	The MedAustron accelerator, located in Wiener Neustadt (Austria), will deliver clinical beams of protons (60-250 MeV) and carbon ions (120-400 MeV/n) to three ion beam therapy irradiation rooms (IR). Clinical beams and proton beams up to 800 MeV will be provided in a fourth IR, dedicated to non-clinical research. A slow-extracted proton beam of maximum clinical energy has been delivered for the first time in IR3 in October 2014, thus providing the technical proof-of-principle of the accelerator chain. The recent related beam commissioning efforts included setting up of the multi-turn injection into the synchrotron at 7 MeV, the acceleration on first harmonic up to 250 MeV, the slow extraction on the third integer resonance with a betatron core and the matching of the High Energy Beam Transfer line. The accelerator optimization phase leading to IR3 medical commissioning of proton beams is ongoing. The main characteristics of the MedAustron accelerator system will be presented, along with the results obtained during the commissioning process.

	In proton and ion storage rings using the third-order resonance extraction mechanism, beam particles are slowly extracted from the ring when reaching the resonance stop-band. Typically at beam injection, the horizontal tune is set to a value close to the resonance value. The tune is then moved towards the resonance value to trigger beam extraction in a controlled way. The tune shift generated by space charge forces needs to be taken into account. For this, the incoherent space-charge tune shift for protons of the MedAustron accelerator main ring has been evaluated. This has been performed by multi-particle tracking using an optics model based on MADX, considering a realistic Gaussian beam distribution and exact non-linear space charge electric field forces. The MedAustron accelerator is in the beam commissioning phase and is planned to start medical commissioning at the end of 2015.
