Funding: This project has received funding from the European Union's Horizon 2020 research and Innovation programme under the Marie Skłodowska-Curie grant agreement No 675265. MedAustron is a synchrotron-based ion therapy center allowing tumour treatment with protons and other light ion species, in particular C6+. Commissioning of all fixed lines, two horizontal and one vertical, has been completed for protons and in parallel to the commissioning of a gantry and C6+, a facility upgrade study is progressing. The upgrade study encompasses the optimization of the slow extraction mechanism by employing the RF empty bucket channeling and RF Knock Out techniques. The former is a front end acceleration technique that suppress spill ripples, fundamental to safely operate the machine at the highest intensities. The latter is an alternative extraction technique which opens up interesting possibilities for fast beam energy and intensity modulations. In this work, we quantify spill smoothening effect achieved with the first and report the results of a feasibility study of the second using a Schottky monitor as a transverse kicker. |

| MOPML027 | Status of Carbon Commissioning of the MedAustron Therapy Accelerator | 457 |
|
||
| The MedAustron therapy accelerator is intended to treat cancer patients with proton and carbon beams of 62-252 MeV and 120-400 MeV respectively. The accelerator features three Supernanogan ECR ion sources, a 400 keV/u RFQ and a 7 MeV/u interdigital H-mode Linac. A middle energy beam transfer line also serves as injector into a 77m synchrotron from which the beam may be transferred to 4 different irradiation rooms, 3 of which are dedicated to medical treatment. The therapy accelerator is in clinical operation since end 2016 and is currently solely configured for the use of protons. The next clinical objective is to enable treatments using C6+ ions which triggered the carbon commissioning of the accelerator in 2017. This paper will discuss the latest results from carbon commissioning in the different sections of the accelerator, achieved efficiencies and outlook on future carbon activities. | ||

| TUPAF004 | Status of the MedAustron Beam Commissioning with Protons and Carbon Ions | 665 |
|
||
| MedAustron is a synchrotron-based Particle Therapy Accelerator located in Wiener Neustadt, Austria, which is delivering beams for medical treatment since end of 2016. The accelerator provides clinical proton beams in the energy range 62-252 MeV and is designed to provide carbon ions in the range 120-400 MeV/n to three ion therapy irradiation rooms IRs, including a room with a proton Gantry. Proton beams of up to 800 MeV will be provided to a fourth room dedicated to research. Presently, proton beams are delivered to the fixed horizontal beam lines of three rooms. Beam commissioning of the vertical beam line of the second IR is being completed and the beam line is in preparation for clinical treatment. Commissioning of the accelerator with carbon ions is advancing and first clinical beams have been sent to the IRs, while the preparation for the Gantry beam line is ongoing. A slow extraction 3rd order resonance method is used to extract particles from the synchrotron between 0.1-10 seconds to favor control of the delivered dose during clinical treatments. The main characteristics of the accelerator and results obtained during the latest commissioning activities are presented. | ||
