  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.

  An international Facility for Antiproton and Ion Research (FAIR) was proposed by GSI in 2001 and is currently under development. This new accelerator complex will be a significant extension to the existing GSI accelerator chain and will provide a range of particle beams from protons and antiprotons to ion beams of all elements up to uranium, as well as secondary beams of short-lived rare isotope beams. The central parts of the FAIR facility are a superconducting double-ring synchrotron and a system of storage rings. This presentation covers the status and scope of the FAIR project and its technical and organizational challenges, in particular in respect to the accelerator control system. As many parts of the new FAIR facility will be independently developed as in-kind contributions by international FAIR partner institutes, one significant point is integration and interface management. Among many other aspects, one important technical consideration is a high degree of parallel beam operation for the different research programs that imposes ambitious demands on the timing and cycle management system. We will discuss first steps towards a new FAIR control system.

  The Spiral2 project at Ganil aims to produce rare ion beams using a uranium carbide target fission process. The accelerator consists of an RFQ followed by a superconducting cavity linac and is designed to provide high-intensity primary beams (deuterons, protons, or heavy ions). The accelerator should be commissioned by the end of 2011, and the first exotic beams are planned for one year later. The control system will be a result of collaboration between several institutes, among which is the Saclay Dapnia division, which has good experience and knowledge with EPICS. Because of its widely used functionalities, EPICS has been chosen as the basic framework for the accelerator control, and people from the other laboratories belonging to the collaboration are progressively acquiring their first experiences with it. The paper first explains the organization of the collaboration, then it describes the basic hardware and software choices for the project. Some preliminary implementations are therefore given. As the project is still in its beginning phase, the paper ends by listing some questions not yet resolved for the control system definition and remaining open to discussion.

  The control system of the RIKEN RI-Beam Factory (RIBF) is based on the Experimental Physics and Industrial Control System (EPICS). To control magnet power supplies of cyclotrons and their beam transport lines, we are using VME and CAMAC as I/O Controllers (IOCs) depending on a kind of their interface boards. To control beam-diagnostic equipment and vacuum systems, small single-board computers mounted with Linux are used as IOCs. Other devices of cyclotrons like RF are controlled by PCs, which are independent systems from EPICS. These details will be reported. Furthermore, we will report about the RIBF beam interlock system using Melsec PLCs. We started beam commissioning of RIBF in July 2006 and succeeded in extracting uranium beam from the Superconducting Ring Cyclotron (SRC), which is the last of the multi-stage accelerators of the RIBF, on March 23, 2007.  
 
TPPB28 Preliminary Design Concepts for the Control and Data Acquisition Systems of the ITER Neutral Beam Injector and Associated Test Facility neutral-beams, controls, site, ion-source 220

  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.

  The TITAN experiment at the ISAC radioactive beam facility consists of an RF cooler system, a Magnetic Penning Trap (MPET), and an Electron Beam Ion Trap (EBIT). These three systems may run together or independently. This paper describes the EPICS-based TITAN control system, which was modeled after the ISAC control system to facilitate integration. Both software and hardware configurations will be described, with emphasis on pulsed diagnostics and the pulse distribution system for synchronizing the traps in different operation modes.  
 
TPPB39 Experiences with an Industrial Control System: Traceability of Specifications, Commissioning Support and Conclusions from the HICAT Project controls, diagnostics, linac, ion-source 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.  
 
WPPA05 The LANSCE Timing System Upgrade controls, diagnostics, linac, synchrotron 325
 
  • E. Bjorklund
    LANL, Los Alamos, New Mexico
  As part of a planned upgrade project for the Los Alamos Neutron Science Center (LANSCE) accelerator, we are considering replacing our current timing system, which distributes each timing signal on its own dedicated wire, with a more modern event-driven system. This paradigm shift in how timing signals are generated and distributed presents several challenges that must be overcome if we are to preserve our current operational capabilities. This paper will discuss some of the problems and possible solutions involved with migrating to an event system. It will also discuss some recent enhancements to theμResearch, Finland (MRF) event system that will help us accomplish our goal.  
 
WPPA06 An Embedded EPICS Controller Based on Ethernet/Serial Box controls, power-supply, target, vacuum 328
 
  • L. R. Shen, G. Y. Jiang
    SSRF, Shanghai
  The control system of SSRF takes the Ethernet as backbone. All kinds of serial devices such as vacuum pumps are connected to Linux IOCs via a kind of Ethernet/serial box made by Moxa company. In the preresearch stage of SSRF, the old model of this Ethernet/serial box was only a simple Ethernet/serial protocol converter which was functioned by firmware. Aim to this, we have developed several kinds of EPICS device drivers based on NetDev for our serial devices. Recently, Moxa company has upgraded the converter by replacing old arm9 CPU with a more powerful Intel Xscale CPU. It supports Monta Vista Linux as its embedded OS, also cross-compiler is provided to make further development available. Since we have decided to use the new model of converter in our facility finally, we manage to port EPICS IOC core on Monta Vista Linux and implement the same function on the new converter as old one's to avoid modifying existent EPICS device driver. By these, the dedicated Linux IOC can be omitted and the whole system can be more efficient and expandable. Details of the necessary integration work and initial operation experience will be discussed in this paper.

  The STAR (Solenoidal Tracker At RHIC) experiment located at Brookhaven National Laboratory has been studying relativistic heavy ion collisions since it began operation in the summer of 2000. An EPICS-based hardware controls system monitors the detector's 40000 operating parameters. The system I/O control uses VME processors and PCs to communicate with sub-system based sensors over a variety of field busses. The system also includes interfaces to the accelerator and magnet control systems, an archiver with CGI web based interface and C++ based communication between STAR online system, run control and hardware controls and their associated databases. An upgrade project is underway. This involves the migration of 60% of the I/O control from the aging VME processors to PC's. The host system has been transferred from Sun OS to Scientific Linux and some of the VME boards were replaced with "softIOC" applications. The experience gained with the current setup will be discussed, and upgrade plans and progress will be outlined.  
 
WPPA17 Spectra Acquisition System for the LNL ECR Ion Source controls, dipole, linac, rfq 350

  Since beginning 2006 the LNL ECR ion source on a 350-kV high-voltage platform must to supply reliable and stable beams for the operation of a linear accelerators complex: the superconducting PIAVE injector and the superconducting linear accelerator ALPI. At the end of 2006 a new spectra acquisition system was put into operation for the ECRIS setup and beam periodic checks. The previously used spectra acquisition system was running only on a local scope on the high-voltage platform while the new system was required to work both on the local and on the remote control computer in the console room. To achieve this goal a set of new devices had to be integrated in the standard remote control system. New software modules had also to be developed and integrated in the existent and working control system. An important goal of this upgrade was to assembly a tool that may be easily installed, used and maintained on different computer platforms (Linux and Windows PCs) and that may cope with future changes in the hardware devices to be used for spectra acquisition. Here a survey of this new facility is given.  
 
WPPA24 EPICS CA Enhancements for LANSCE Timed and Flavored Data controls, site, proton, diagnostics 365
 
  • J. O. Hill
    LANL, Los Alamos, New Mexico
  Currently the subscription update event queue in the EPICS server is capable of carrying event payloads consisting always of the channel’s value, time stamp, and alarm state. The complexity of the LANSCE macro pulse beam gates requires unique capabilities within the LANSCE control system - which is currently only partly based on an EPICS core. Upgrade designs specify a 100% EPICS based system, but this has evolved new requirements for enhanced capabilities within EPICS. Specifically, EPICS Channel Access (CA) clients need to dynamically specify the LANSCE macro pulse beam gate combinatorial (LANSCE Flavored Data), and the timing offsets (LANSCE Timed Data), to be viewed when they subscribe. EPICS upgrades in progress fulfilling these requirements, including generic software interfaces accommodating site specific event queue payloads and client specified subscription update filters, will be described.

  MicroIOC is an affordable, compact, embedded computer designed for controlling and monitoring of devices via a control system (EPICS, ACS, and TANGO are supported). Devices can be connected to microIOC via Ethernet, serial, GPIB, other ports, or directly with digital or analog inputs and outputs, which makes microIOC a perfect candidate for a platform that integrates devices into your control system. Already over 90 microIOCs are installed in 18 labs over the world. LOgarithmic COnverter (LOCO) is a specialized microIOC used as a high-voltage power-supply distribution system for vacuum ion pumps. A single high-voltage power-supply controller can be used for delivering power to multiple ion pumps. A highly-accurate logarithmic-scale current measurement is provided on each pump, enabling an affordable and reliable pressure measurement ranging from 10-12 to 10-4 mbar.

  After a 15-month construction period, the CERN Control Centre (CCC) began operating on February 1st, 2006. The CCC now controls all of CERN's accelerators, technical infrastructure, and cryogenics plants. In addition, most LHC experiments as well as other scientific laboratories throughout the world, are adopting some of its design options (furniture, layout, colours, …) for their own control rooms. This paper presents the main ideas behind the ergonomic choices.  
 
RPPB29 Requirements and Coherent Realization of the HICAT Control System Functionality for Test, Commissioning, and Operation controls, synchrotron, diagnostics, linac 674
 
  • R. Baer, M. Schwickert, T. Fleck
    GSI, Darmstadt
  The control system for the HICAT project comprises several rather different functionalities for the whole range of demands starting from tests of single components up to the specified operation mode where the accelerator has to deliver a beam of high-energy ions with requested energy, focus and intensity for tumor treatment. We outline the concept and realization of this system which is capable of fulfilling all those needs within the implemented functions and GUIs. The range of functionality spans from test environments and trace-possibilities for single front-end controllers up to complete integrity tests of the whole accelerator for the designed operation mode. For example, for commissioning of the LINAC division the control system utilizes a 5Hz mode while typical synchrotron cycles last for several seconds and can be used with similar adjustments. In normal operation mode diagnostics like beam current are only evaluated at special times in a cycle, but it is possible to monitor and record these data at high sampling rates in a continuous mode over several hours. Furthermore it is possible to accomplish long-term stability tests of single components during normal operation.
