	HIT is the first dedicated proton and carbon cancer therapy facility in Europe. It uses the full 3D intensity controlled raster scanning dose delivery method of pencil beams with ion beams of 48 - 430 MeV/u provided by a linac-synchrotron-system. Ion beams in this wide range of energies, different beam sizes, and intensities have to be provided by the control system to all treatment rooms at any time with high accuracy, stability, and reproducibility. This paper briefly reflects some aspects of the data supply, i. e. the settings of accelerator devices at a medical accelerator. This includes the generation of control data, storage, and data recovery routines, which have been developed at HIT in the recent years. That is in particular the management of verified therapy data and settings, which are stored in a non-volatile memory of the device controllers, and – as a backup – in a database and which are protected against unintended changes for safety reasons.

HIT is the first dedicated proton and carbon cancer therapy facility in Europe. It uses the full 3D intensity controlled raster scanning dose delivery method of pencil beams with ion beams of 48 - 430 MeV/u provided by a linac-synchrotron-system. Ion beams in this wide range of energies, different beam sizes, and intensities have to be provided by the control system to all treatment rooms at any time with high accuracy, stability, and reproducibility. This paper briefly reflects some aspects of the data supply, i. e. the settings of accelerator devices at a medical accelerator. This includes the generation of control data, storage, and data recovery routines, which have been developed at HIT in the recent years. That is in particular the management of verified therapy data and settings, which are stored in a non-volatile memory of the device controllers, and – as a backup – in a database and which are protected against unintended changes for safety reasons.
