A new access control unit for GANIL and SPIRAL 2

International audienceFor the GANIL safety revaluation and the new project of accelerator SPIRAL 2, it was decided to replace theexisting access control system for radiological controlled areas. These areas are all cyclotron rooms and experimental areas. The existing system is centralized around VME cards. Updating is becoming very problematic. The new UGA (access control unit) will becomposed of a pair of PLC to ensure the safety of each room. It will be supplemented by a system UGB (radiological control unit) that will assure the radiological monitoring of the area concerned

A Small but Efficient Collaboration for the Spiral2 Control System Development

http://accelconf.web.cern.ch/AccelConf/ICALEPCS2013/papers/tucobab01.pdfThe Spiral2 radioactive ion beam facility to be commissioned in 2014 at Ganil (Caen) is built within international collaborations. This also concerns the control system development shared by three laboratories: Ganil has to coordinate the control and automated systems work packages, CEA/IRFU is in charge of the "injector" (sources and low energy beam lines) and the LLRF, CNRS/IPHC provides the emittancemeters and a beam diagnostics platform. Besides the technology Epics based, this collaboration, although being handled with a few people, nevertheless requires an appropriate and tight organization to reach the objectives given by the project. This contribution describes how, started in 2006, the collaboration for controls has been managed both from the technological point of view and the organizational one, taking into account not only the previous experience, technical background or skill of each partner, but also their existing working practices and "cultural" approaches. A first feedback comes from successful beam tests carried out at Saclay and Grenoble; a next challenge is the migration to operation, Ganil having to run Spiral2 as the other members are moving to new projects

Irradiation control of the “SPIRAL1” target by measuring the ion beam intensity: “CICS” Project

International audienceIn order to obtain a more precise control on the irradiation of the targets of the “SPIRAL1” installation and to optimize the experiments schedule as well as the exploitation costs, a new criterion of safety is respected. This new safety criterion is the maximum dose (maximum number of ions stopped in the Spiral1 Target). To control this, an AQ system has been put in operation and more specifically a new device has been set up in order to measure the ion beam intensity and to calculate the number of particules per second. This value can then be integrated over time. This device mainly consists of two redundant instrumentations, which are acquired via a real time industrial controller. The accuracy of measurement is estimated taking into account the variation of beam, of the environment and of the installation. This system obtained the agreement of the French nuclear safety authorities and is operational since September 2007

First partial cool down of the SPIRAL 2 LINAC

International audienceSpiral2 is a rare isotope accelerator dedicated to the production of some of the highest intensitybeams on earth. Its driver is a superconducting linear accelerator that takes advantages of 26 bulkniobium quater wave accelerating cavities. It takes up to 1000W@4K, 95 cryo-valves and 22automations systems to cryogenically operate the LINAC. The talk will present the achievement ofyears of hardwork to make the first trials of the LINAC partial cool down with its successes andchallenges

The new accelerator control system of GANIL

International audienceThe new computer control system has operated the heavy ion accelerator GANIL from the beginning of 1993 and has reached a state of routine operation. It supersedes the obsolete initial system to cope with the harsh experimental conditions required by the very high intensity beams expected in the near future. Hardware and software implementations, as well as the human interface, are presented. Emphasis is placed on the three-layer distributed architecture adopted. An Ethernet local area network (LAN) links the basic components: a VAX/VMS cluster, XWINDOWS-interfaced operator consoles, VAXELN-driven CAMAC crate controllers and programmable logic controllers for the front end controls. Also the data management, through the INGRES relational database management system (RDBMS), as well as the operating software written in ADA, are described. The early experience with the new control system is reported and future developments discussed
