  On 16th March 2019, Varian celebrated the 10th anniversary of first patient treatment in the Munich Proton Center, Germany. Since the first cyclotron installation, 22 more 250 MeV superconducting isochronous proton cyclotrons have successfully been manufactured, commissioned, and tested in our Troisdorf production line. During this process, an increasing experience with the cyclotron’s internal mechanisms and underlying physics allowed for a nowadays significant faster commissioning lead time without having changed the hardware setup substantially. Furthermore, we can already verify full clinical performance of each cyclotron in the factory test cells before delivery to the customer. Essential improvements in the areas of qualification of magnetic field configuration, RF conditioning, and beam commissioning are presented.
