	Conventional slow extraction driven by a tune sweep perturbs the optics and changes the presentation of the beam separatrix to the extraction septum during the spill. The constant optics slow extraction (COSE) technique, recently developed and deployed operationally at the CERN Super Proton Synchrotron to reduce beam loss on the extraction septum, was implemented at MedAustron to facilitate extraction with a tune sweep of operational beam quality. COSE fixes the optics of the extracted beam by scaling all machine settings with the beam rigidity following the extracted beam’s momentum. In this contribution the implementation of the COSE extraction technique is described before it is compared to the conventional tune sweep and operational betatron core driven cases using both simulations and recent measurements.

Using the rotator, all beam parameters at the location of the patient become independent of the gantry rotation angle. Furthermore, both the gantry and the high energy transfer line optics had to be redesigned and adapted to the rotator-mode of operation.

The MedAustron Particle Therapy Accelerator located in Austria, delivers proton beams in the energy range 60-250 MeV/n and carbon ions 120-400 MeV/n for medical treatment in two irradiation rooms, clinically used for tumor therapy. Proton beams up to 800 MeV/n are also provided to a room dedicated to scientific research. Over the last two years, in parallel to clinical operations, we have completed the installation and commissioning of the gantry beam line in a dedicated room, ready for the first patient treatment in early 2022. In this manuscript, we provide an overview of the MedAustron gantry beam commissioning including the world-wide first ’rotator’ system, a rotating beamline located upstream of the gantry and used to match the slowly extracted non-symmetric beams into the coordinate system of the gantry. Using the rotator, all beam parameters at the location of the patient become independent of the gantry rotation angle. Furthermore, both the gantry and the high energy transfer line optics had to be redesigned and adapted to the rotator-mode of operation. A review of the beam commissioning including technical solutions, main results and reference measurements is presented.
