  Mainly for carrying out nuclear physics experiences, the SPIRAL2 facility based at Caen in France will aim to provide new radioactive rare ion or high intensity stable ion beams. The driver accelerator uses several radiofrequency systems: RFQ, buncher and superconducting cavities, driven by independent amplifiers and controlled by digital electronics. This low level radiofrequency subsystem is integrated into a regulated loop driven by the control system. A test of a whole system is foreseen to define and check the computer control interface and applications. This paper describes the interfaces to the different RF equipment into the EPICS based computer control system. CSS supervision and foreseen high level tuning XAL/JAVA based applications are also considered.

  Spiral2 whose construction physically started at the beginning of this year at Ganil (Caen, France) will be a new Radioactive Ion Beams facility to extend scientific knowledge in nuclear physics, astrophysics and interdisciplinary researches. The project consists of a high intensity multi-ion accelerator driver delivering beams to a high power production system to generate the Radioactive Ion Beams being then post-accelerated and used within the existing Ganil complex. Resulting from the collaboration between several laboratories, Epics has been adopted as the standard framework for the control command system. At the lower level, pieces of equipment are handled through VME/VxWorks chassis or directly interfaced using the Modbus/TCP protocol; also, Siemens programmable logic controllers are tightly coupled to the control system, being in charge of specific devices or hardware safety systems. The graphical user interface layer integrates both some standard Epics client tools (EDM, CSS under evaluation, etc …) and specific high level applications written in Java, also deriving developments from the Xal framework. Relational databases are involved into the control system for equipment configuration (foreseen), machine representation and configuration, CSS archivers (under evaluation) and Irmis (mainly for process variable description). The first components of the Spiral2 control system are now used in operation within the context of the ion and deuteron sources test platforms. The paper also describes how software development and sharing is managed within the collaboration.

  The SPIRAL2 linear accelerator will produce entirely new particle beams enabling exploration of the boundaries of matter. Coupled with the existing GANIL machine this new facility will produce light and heavy exotic nuclei at extremely high intensities. The field deployment of the Control System relies on Linux PCs and servers, VME VxWorks crates and Siemens PLCs; equipment will be addressed either directly or using a Modbus/TCP field bus network. Several laboratories are involved in the software development of the control system. In order to improve efficiency of the collaboration, special care is taken of the software organization. During the development phase, in a context of tough budget and time constraints, this really makes sense, but also for the exploitation of the new machine, it helps us to design a control system that will require as little effort as possible for maintenance and evolution. The major concepts of this organization are the choice of EPICS, the definition of an EPICS directory tree specific to SPIRAL2, called "topSP2": this is our reference work area for development, integration and exploitation, and the use of version control system (SVN) to store and share our developments independently of the multi-site dimension of the project. The next concept is the definition of a "standardized interface" between high level applications programmed in Java and EPICS databases running in IOCs. This paper relates the rationale and objectives of this interface and also its development cycle from specification using UML diagrams to testing on the actual equipment.
