TOAA02	Status of the Control System for HICAT at an Advanced Stage of Commissioning: Functions, Restrictions and Experiences	controls, ion, diagnostics, target	47
	R. Baer, M. Schwickert, T. Fleck GSI, Darmstadt
	One and a half years after installation of the first components, much progress has been made in commissioning of the accelerator for the clinic in Heidelberg. In the final state it is designed to produce different kinds of heavy ions with energies up to 430 MeV/u to treat about 1300 tumor patients a year at three therapy rooms. Presently the specified parameter space for patient treatment is filled to meet the correct combinations of energies, beam foci, and intensities for the therapy. In this contribution we will first shortly describe the concept of the control system which was designed by GSI but developed by an all-industrial partner who furthermore delivered the front-end control units and has another contract with Siemens Medical Solutions to meet the requirements at the interface to the therapy control system. We will mainly focus on its abilities and experiences with it: different kinds of beam requests, time accuracy, real-time analysis, assurance of consistent device data, offline-diagnostics and the beam diagnostic systems. We also report on known restrictions and the concept to securely provide different operation modes for accelerator adjustment or patient treatment.

	ITER is a joint international research and development project aiming to demonstrate the scientific and technical feasibility of fusion power. The ITER Neutral Beam Injector (NBI, negative D2 ion source, 1MV acceleration voltage, 40A ion current, 16.5MW beam power, 1 hour continuous operation) is a major component of ITER and will be supported by a dedicated test facility (NBTF). The NBI and the NBTF are being designed with the goal to have one injector fully operational on the ITER device in 2016. The two items need separate, but closely interacting, control and data acquisition systems (CDAs). The NBI CDA system will manage the NBI device and will be installed at the ITER site; the NBTF CDA system will manage the test facility and in particular will enable extensive scientific exploitation of the NBI before its final installation at the ITER site. The paper reports on the design activity for both CDA systems, including the definition of the system requirements, the functional system structure, and the preliminary system architecture.
TPPB39	Experiences with an Industrial Control System: Traceability of Specifications, Commissioning Support and Conclusions from the HICAT Project	controls, ion, diagnostics, linac	247

	While the accelerator for HICAT was designed by GSI, most components and systems were supplied by industrial partners. Despite thorough and detailed specifications for the control system, the concept allowed a rather high degree of freedom for the industrial partner regarding the implementation. The challenge of this combination established a good understanding of the necessary functionalities by our industrial partner. First, we describe the process of implementation starting with the specifications made, sum up the tracing of the development, and show how we ensured proper functionality ab inito and necessary steps since then. Second, we describe problems ranging from software bugs to demands regarding acceptance tests for other components and state how we managed to solve these problems with our industrial partner on a short timescale. Last, we show what can be learned from our experiences. In particular we discuss where it is more efficient to describe all necessary physical dependencies to the industrial partner instead of defining a proper interface where the programming can be done by accelerator experts and concentrate on areas that led to problems with the time schedule.
WPPA34	Extended Application Fields for the Renovated GSI Control System	controls, septum, synchrotron, coupling	386

	The current GSI control system uses a very monolithic approach that made it difficult to extend the system to other than the original platforms (VME front ends and OpenVMS on the application level). For the present renovation project of the communication layers, flexibility was a major design criterion. Front-end and application levels are connected via CORBA middleware, giving free choice for using various system architectures and programming languages on both levels. While most of the current front-end software will be ported to the existing VME front-end environment, now running Linux, the new system can integrate devices running on various architectures and operating systems into the new GSI control system. To model equipment functionality as independently as possible, generating adapter code from a well-defined XML description of device models is now under development. This will make the task of porting the existing 65 device models (including around 3000 properties) to the new modular approach easier. We will present the current state of this project and future plans.
