    HIT, Heidelberg
  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 Spiral2 project is aiming to provide high intensity rare ion beams for nuclear physics experiments. It is based first on a primary beam driver accelerator consisting of a RFQ followed by a superconducting L. I.N. A.C., then a rare ion production process delivers the beam either to a low energy experimental area or to the existing Ganil facility. The EPICS software has been chosen as the basic framework to improve efficient collaboration between several research laboratories (CEA-IRFU, CNRS-IPHC, GANIL) which are designing the accelerator control system. The whole facility will integrate more than 600 power supplies used for the magnetic and high voltage equipment control of the accelerator. It has been decided to interface these power supplies through the MODBUS/TCP protocol, using Ethernet as a field bus. This paper introduces the EPICS software archetype set up to assess the practicability of such a solution and presents a first implantation for prototyping.

  The control system for an FFAG accelerator complex in KURRI (Kyoto University Research Reactor Institute) is based on PLC and LabVIEW on PC. In order to manage a lot of parameters of accelerator all through the operations, the data-logging system using SQL server and Web-browsing databases using PHP have been constructed. Some data-transfer methods were attempted for the purpose of getting the effective data processing cycle in our environment. The construction method and the performance of our data-logging system will be introduced in the presentation.

  The Spiral2 project consists of a new facility to provide high intensity rare ions beams. It is based on a primary beam driver accelerator (RFQ followed by a superconducting linac) and a rare ion production process delivering the beam either to a low energy experimental area or to the existing Ganil facility. From October this year, one ion source coupled with a first beam line section will be in test; then, the injector (ion and deuteron sources, RFQ) will be tested by the end of 2010 so the whole accelerator should be commissioned by the end of 2011; the first exotic beams being planned one year later. The accelerator control system design results from the collaboration between several institutes and Epics has been chosen as the basic framework. The paper therefore presents the main choices: MVME5500 CPUs, VME I/O boards, VxWorks, Siemens PLCs, Modbus field buses, EDM screens and Java applications, Linux PCs, use of a LabView/Epics gateway<br/>Specific topics are the evaluation of the XAL environment, an Epics design to address the power supplies, an emittance measurement system, the development of a beam profiler interface and the investigation for a triggered acquisition system.

  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.  
 
WEP005 Monolithic DAQ System for Beam Diagnostics at the HIT Medical Accelerator Facility controls, diagnostics, synchrotron, medical-accelerators 177
 
  • M. Schwickert, T. Fleck, A. Reiter
    GSI, Darmstadt
  The Heidelberg Ion Therapy Center HIT is presently in the final phase of commissioning. HIT consists of a two-stage linac followed by a compact heavy-ion synchrotron. The ion beam can be delivered to two horizontal treatment places and a gantry structure for 360° patient treatment. In this contribution we report on the basic concepts for the integration of the beam diagnostic data acquisition into the overall accelerator control system and the distributed timing devices. The equipment-side abstraction layer of facility-wide device classes and its seamless integration besides device control units, e.g. for power supplies, is presented and first operational experiences of the machine commissioning are discussed. As examples for the data acquisition of the high-energy beam transport section the detection of beam profiles using MWPCs and Scintillation Screens is presented, as well as measurements of beam intensity using ionization chambers.

  At the GSI accelerator facility, several optical beam instrumentation devices for transversal profile measurement are installed. Their readout is done with FireWire CCD cameras attached to a small embedded device, specialized for image processing tasks (National Instruments Compact Vision System 1456). Here a LabView application preprocesses the images based on user requests. The resulting data (e.g. projections, histograms, compressed or original images) is sent over ethernet to a Windows or Linux PC, reaching frame rates above 30fps at VGA resolution. Using C++ with Qt libraries for networking and GUI purposes, platform independence without source code modification is achieved. In this paper we present the system components and software design to control CCD cameras and various other devices with an easy-to-use graphical user interface for machine operators.

WEP007 FESA - The Front-End Software Architecture at FAIR controls, diagnostics, monitoring, instrumentation 183
 
  • T. Hoffmann
    GSI, Darmstadt
  The planned Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt is a very challenging task due to its dimension and complexity. Several new heavy ion accelerators have to be built and then operated in parallel and multiplexed modes. In order to cope with these unique requirements numerous collaboration partners are involved to add so-called ”in-kind contributions” to the project. Detailed guidelines and interface specifications have to be defined in advance to avoid an indefinite pool of different technologies which have to be handled by the future control system. For that purpose, GSI decided to use the Front-end Software Architecture (FESA) at the lowest level of the control system. FESA was developed by CERN and is already established for usage at LHC and its injectors. It is a framework to integrate any kind of equipment such as beam instrumentation devices, magnet power supplies, vacuum- and cryogenic components into the control system. A framework overview, its advantages, and boundary conditions provided by FESA are described.

  Shortly before first tumour patients will be treated with high-energy ions at the facility in Heidelberg we give an overview of the control systems special characteristics, current status and remaining functionality to completion. The control system was designed by GSI but has been developed by an all-industrial partner. At each of the three therapy rooms more than 20000 combinations of beam energy, intensity and focus can be requested by the therapy control system. The commissioning for carbon and proton ion beams has already been conducted by GSI. We show how different operating conditions are implemented to ensure at the same time the possibility for experimental research while beam properties already verified within medical test procedures must not be altered without following predefined workflows. Therefore all system and device parameters as well as all set values that possibly change beam properties for patient treatment have to be securely locked or e.g. integrated into checksums. We will also focus on several minor and a few major changes in functionality that had to be implemented to conform to the requirements that originated by the risk assessment of the control system.
