The HIT (Heidelberg Ion Beam Therapy) Centre is the first heavy ion therapy accelerator in Europe, which is operated by the university hospital of Heidelberg, Germany. In accordance with the german radiological protection ordinance, a personnel safety system (PSS) was installed during the comissioning of the accelerator. Main functions of the PSS are radiation protection, gate control, emergency stop handling, change of the state of the protection areas and safety interlocks. The PSS is a stand alone part of the accelerator control system and consists of several OPC servers and a special designed GUI for the control room. The installation of the PSS was started in June 2006 and finished in March 2008. This presentation will report on the concept and realization of the PSS.

The HIT ACS is a modular, PC and front-end controller (with FPGAs) based accelerator control system developed by the company Eckelmann AG, Wiesbaden, Germany in cooperation with GSI and HIT. It consists of a database and several central applications running on Windows 2k3 server machines as well as a dozen control room client PCs for the GUIs, and a few hundred front-end device controlling units (DCUs). Due to strict timing requirements in the ms and partly μs range, communications during an acceleration cycle are done in real-time via RTB (Real Time Bus) and real-time shared memory components on the main control server. We show the overall structure of the ACS network and outline the relation of the component devices and the Ethernet and RTB communications between them.
