The commissioning of the Spiral2 Radioactive Ion Beams facility at Ganil will soon start, so requiring the control system components to be delivered in time. Yet, parts of the system were validated during preliminary tests performed with ions and deuterons beams at low energy. The control system development results from the collaboration between Ganil, CEA/IRFU, CNRS/IPHC laboratories, using appropriate tools and approach. Based on Epics, the control system follows a classical architecture. At the lowest level, Modbus/TCP protocol is considered as a field bus. Then, equipment are handled by IOCs (soft or VME/VxWorks) with a software standardized interface between IOCs and clients applications on top. This last upper layer consists of Epics standard tools, CSS/BOY user interfaces within the so-called CSSop Spiral2 context suited for operation and, for machine tunings, high level applications implemented by Java programs developed within a Spiral2 framework derived from the open-Xal one. Databases are used for equipment data and alarms archiving, to configure equipment and to manage the machine lattice and beam settings. A global overview of the system is therefore here proposed.

The Spiral2 linear accelerator will drive high intensity beams, up to 5mA, to up to 200kW at linac exit. Such beams can seriously damage and activate the machine ! To prevent from such situation, the Machine Protection System (MPS) has been designed. This system is connected to diagnostics indicating if the beam remains under specific limits. As soon as a diagnostic detects its limit is crossed, it informs the MPS which will in turn take actions that can lead to a beam cut-off in appropriated timing requirements. In this process, the Beam Loss Monitors (BLM) are involved in monitoring prompt radiation generated by beam particles interactions with beam line components and responsible for activation, on one side, and thermal effects, on the other side. BLM system relies mainly on scintillator detectors, NIM electronics and a VME subsystem monitoring the heating of the machine. This subsystem, also called «Thermal BLM», will be integrated in the Spiral2 EPICS environment. For its development, a specific project organization has been setup since the development is subcontracted to Cosylab. This paper focuses on the Thermal BLM controls aspects and describes this development process.

The 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
