Brookhaven National Laboratory (BNL) is one of the premier high energy and nuclear physics laboratories in the world and has been a leader in accelerator based physics research for well over half a century. For the past ten years experiments at the Relativistic Heavy Ion Collider (RHIC) have recorded data from collisions of heavy ions and polarized protons, leading to major discoveries in nuclear physics and the spin dynamics of quarks and gluons. BNL is also the site of one of the oldest alternating gradient synchrotrons, the AGS, which first operated in 1960. The accelerator controls systems for these instruments span multiple generations of technologies. In this report we will describe the current status of the Collider-Accelerator Department controls systems, which are used to control seven different accelerator facilities (from the LINAC and Tandem van de Graafs to RHIC) and multiple science programs (high energy nuclear physics, high energy polarized proton physics, NASA programs, isotope production, and multiple accelerator research and development projects). We will describe the status of current projects, such as the just completed Electron Beam Ion Source (EBIS), our R&D programs in superconducting RF and an Energy Recovery LINAC (ERL), innovations in feedback systems and bunched beam stochastic cooling at RHIC, and plans for future controls system developments.

The Heidelberg Ion Therapy Center (HIT) is a heavy ion accelerator facility located at the Heidelberg university hospital and intended for cancer treatment with heavy ions and protons. It provides three treatment rooms for therapy of which two using horizontal beam nozzles are in use and the unique gantry with a 360° rotating beam port is currently under commissioning. The proprietary accelerator control system runs on several classical server machines, including a main control server, a database server running Oracle, a device settings modeling server (DSM) and several gateway servers for auxiliary system control. As the load on some of the main systems, especially the database and DSM servers, has become very high in terms of CPU and I/O load, a change to a more up to date blade server enclosure with four redundant blades and a 10Gbit internal network architecture has been decided. Due to budgetary reasons, this enclosure will at first only replace the main control, database and DVM servers and consolidate some of the services now running on auxiliary servers. The internal configurable network will improve the communication between servers and database. As all blades in the enclosure are configured identically, one dedicated spare blade is used to provide redundancy in case of hardware failure. Additionally we plan to use virtualization software to further improve redundancy and consolidate the services running on gateways and to make dynamic load balancing available to account for different performance needs e.g. in commissioning or therapy use of the accelerator.

The 180 MeV proton beam from the cyclotron at The Svedberg Laboratory is primarily used for a patient treatment. Because of the fact that the proton beam is needed only during a small fraction of time scheduled for the treatment, there is a possibility to divert the beam to another location to be used by a secondary user. The therapy staff (primary user) controls the beam switching process after an initial set-up which is done by the cyclotron operator. They have an interface that allows controlling the accelerator and the beam line in all aspects needed for performing the treatment. The cyclotron operator is involved only if any problem occurs. The secondary user has its own interface that allows a limited access to the accelerators control system. Using this interface it is possible to start and stop the beam when it is not used for the therapy, grant access to the experimental hall and monitor the beam properties. The tools and procedures for the beam sharing between the primary and the secondary user are presented in the paper.

At PSI there are two facilities with proton cyclotron accelerators. The machine control system for PROSCAN which is used for medical patient therapy, is running with EPICS. The High Intensity Proton Accelerator (HIPA) is mostly running under the in-house control system ACS. Dedicated parts of HIPA are under EPICS control. Both these facilities are configured through an Oracle database application suite. This paper presents the concepts and tools which are used to configure the control system directly from the database-stored configurations. Such an approach has advantages which contribute for better control system reliability, overview and consistency.

The first beam line addition to the SARAF facility was completed in phase I. two experiments are planned in this new beam line, the Liquid Lithium target and the Foils target. For those we are currently building hardware and software for their control systems. The Liquid Lithium target is planned to be a powerful neutron source for the accelerator, based on the proton beam of the SARAF phase I. The concept of this target is based on a liquid lithium that spins and produces neutron by the reaction Li7(p,n)Be7. This target was successfully tested in the laboratory and is intended to be integrated into the accelerator beam line and the control system this year. The Foils Target is planned for a radiation experiment designed to examine the problem of radiation damage to metallic foils. To accomplish this we have built a radiation system that enables us to test the foils. The control system includes varied diagnostic elements, vacuum, motor control, temp etc, for the two targets mentioned above. These systems were built to be modular, so that in the future new targets can be quickly and simply inserted. This article will describe the different control systems for the two targets as well as the design methodology used to achieve a reliable and reusable control on those targets.

The High Intensity Proton Accelerator (HIPA) control system network is spread through about six buildings and has grown historically in an unorganized way. It consisted of about 25 network switches, 150 nodes and 20 operator consoles. The miscellaneous hardware infrastructure and the lack of the documentation and components overview could not guarantee anymore the reliability of the control system and facility operation. Therefore, a new network, based on modern network topology, PSI standard hardware with monitoring and detailed documentation and overview was needed. We would like to present the process how we successfully achieved this goal and the advantages of the clean and well documented network infrastructure.

The Soreq Applied Research Accelerator Facility (SARAF) is a proton/deuteron RF superconducting linear accelerator, which was commissioned at Soreq NRC. SARAF will be a multi-user facility, whose main activities will be neutron physics and applications, radio-pharmaceuticals development and production, and basic nuclear physics research. The SARAF Accelerator Control System (ACS) was delivered while still in development phase. Various issues limit our capability to use it as a basis for future phases of the accelerator operation and need to be addressed. Recently two projects have been launched in order to streamline the system and prepare it for the future development of the accelerator. This article will describe the plans and goals of these projects, the preparations undertaken by the SARAF team, the design principles on which the control methodology will be based and the architecture which is planned to be implemented. The rebuilding process will take place in two consecutive projects. The first will revamp the network architecture and the second will involve the actual rebuilding of the control system applications, features and procedures.

SPES (Selective Production of Exotic Species) is an INFN project to produce Radioactive Ion Beams (RIB) at Laboratori Nazionali di Legnaro (LNL). The RIB will be produced using the proton induced fission on a Direct Target of UCx. In SPES the proton driver will be a Cyclotron with variable energy (15-70 MeV) and a maximum current of 0.750 mA on two exit ports. The SPES Access Control System and the Dose Monitoring will be integrated in the facility Protective System to achieve the necessary high degree of safety and reliability and to prevent dangerous situations for people, environment and the facility itself. A Quality and Safety Management System for SPES (QSMS) will be realized at LNL for managing all the phases of the project (from design to decommissioning), including therefore the commissioning and operation of the Cyclotron machine too. The Protective System, its documents, data and procedures will be one of the first items that will be considered for the implementation of the QSMS of SPES. Here a general overview of SPES Radiation Protection System, its planned architecture, data and procedures, together with their integration in the QSMS are presented.
