Commissioning operations and performances of the Dose Delivery system for CNAO

The first Italian hospital-based facility for hadron therapy, the Centro Nazionale di Adroterapia Oncologica (CNAO), is treating patients since a few weeks. The optimization and commissioning of the Dose Delivery system have been performed in the course of the current year and were concluded in August 2011. After a short introduction on the CNAO and the Dose Delivery features, the paper describes the main operations from the Treatment Planning System output to the end of the particle delivery operation. A second section focuses on the tests and measurements performed for the commissioning reporting also on the measured performances. The Dose Delivery short-term perspectives are then added to the conclusions.
