Description
In ion beam therapy most cancer patients are treated using the raster-scanning dose delivery method of heavy ion pencil beams, with the penetration depth determined by the ion beam energy. The beams are provided by synchrotrons, which currently have to start a new cycle to change the beam energy. The number of particles available in one cycle typically exceeds the required amount for a single energy. Thus changing the beam energy by reacceleration of the stored beam could significantly reduce the overall treatment duration.
Within the HITRIplus project a novel accelerator control system will be designed, which will enable multiple reaccelerations within one synchrotron cycle. As this drastically increases the amount of parameter combinations, it is no longer feasible to use pre-calculated control data for each cycle. Instead the data will be calculated on-the-fly by the device controllers when a new energy is requested.
Here, we will present the current status of the data generation strategy and the architectural model of the new accelerator control system.
