The Marburg Ion-Beam Therapy Centre (MIT) has been in clinical operation since October 2015. The raster scanning technique provides a precise and accurate radiation dose application employing beams of either protons or carbon nuclei. The accelerator, developed by Siemens/Danfysik, consists of an RF linear accelerator and a 65 m synchrotron. During treatment, the position, shape and intensity of the ion beam is monitored online at the beam outlet by the Therapy Control System. In addition, the quality of the beam along the accelerator is monitored by online measurements of beam properties using non-invasive beam diagnostics as well as by dedicated daily performance checks involving also destructive measurements. We present our experience on the machine stability from the first two years of operation of MIT as well as ongoing work to improve analysis tools for long-term monitoring of beam properties. A possible extension of the daily quality assurance tests based on the experience gathered so far is under investigation.
