DRAFT The business and presentation tier services and applications are based on the Spring framework. Spring, being an industrial standard defined by a set of specifications and APIs, is based on Java programming language. Components are the key technology to write modular object-oriented distributed applications. The GUI applications will be based on a set of common control system services and generic components in order to avoid duplication of effort and solutions. All operational applications will use the provided interfaces which represent the "software view" of the ACS. The operational software development process relies on common development tools, guidelines and procedures for the design, implementation, testing, integration, deployment and change management. By defining and implementing such a software development framework for services and GUI applications, the developers can concentrate on writing code for the accelerator controls components such as parameter management, setting generation, cycle handling, trim management; they do not have to write system level services. 2.4.A2.9 Accelerator Settings and Management The GSI/FAIR accelerators and beam lines will be set and manipulated as much as possible on the base of high level physical values. The generation and management of complex settings is a functionality provided by dedicated services in the business tier of the ACS. They are based on theoretical machine models and ion-optical simulation programs. Additionally, operators and machine specialists can apply small corrections (trims) to settings that need to be handled. In order to obtain and preserve a comprehensive and coherent architecture for setting generation and management a modular framework will be provided. Every machine (linac, synchrotrons, storage rings, beam lines, etc.) will be represented by a machine manager (MM) service that provides an API to individual machine models. These might be implemented highly machine specific based on a set of make-rules which derive device specific settings from high level machine parameters. For the ring-machines (synchrotrons and storage rings) a generic model that can be highly customized is foreseen by the machine specialists. In order to handle dependencies from other machines, organize and optimize the timing for cycle management of the FAIR complex a coordinating beam manager (BM) service will be implemented. The BM interfaces with all individual MM, accounts for maximum parallel operation, external constraints like dynamic cryogenic and energy load, and can be operated by the central cycle management application. This application allows editing cycles in the accelerator chain and will assist the user in finding an optimal sequence. 2.4.A2.10 Industrial Controls Some of the technical subsystems of the FAIR facility (e.g. machine cryogenics, vacuum system, facility monitoring) are not time-critical and highly industrial related. The control of these systems is foreseen to be realized based on a common industrial automation system (SCADA, supervisory control and data acquisition system) and integrated into the ACS. There are several advantages to this approach: A SCADA system is highly available and reliable and will run autonomously, de- 166
DRAFT coupled from the ACS which is an important aspect for cryogenics and vacuum. Experience shows that industrial partners can be contracted to follow technical and functional specification to deliver turn-key solutions. Despite the autonomous controls, the industrial control system will however be fully integrated into the ACS by a gateway functionality. The UNICOS framework (unified industrial control system) developed at CERN which is based on the commercial SCADA product PVSS2 is a strong candidate to be evaluated for use at FAIR. This framework provides components, methodology and tools to design, build and program industrial based control systems. 2.4.A3 Survey and Alignment 2.4.A3.1 General Considerations This section describes common aspects of Survey and Alignment (S&A) that are significant for the accurate positioning of FAIR components in general. Surveying activities in support of any constructional work are not covered here and are not in scope of the S&A team. 2.4.A3.1.1 Role of Survey and Alignment in FAIR: major tasks The fundamental task of survey and alignment in the context of the construction of accelerators is the precise physical and geometrical positioning of machine elements, especially dipoles, quadrupoles, beam diagnostic devices, collimators etc. according to an exactly specified nominal position – the lattice – and the required alignment tolerances. An additional part of the scope of work is the metrological support to the physics experiments such as providing geodetic infrastructure in the experimental areas, aid on the installation of particle detectors and precise spatial measurement of such detectors. It has to be emphasized that a precise alignment is needed not only for the first installation; but also the regular control of the actual position of the accelerator and the preservation of the nominal values over a long period is under the responsibility of the S&A team. 2.4.A3.1.2 Basic survey and alignment steps (installation phase) Accelerator components need to be aligned to very tight tolerances. In order to perform these tasks, fundamental work packages are essential: • Definition of appropriate coordinate systems • <strong>Design</strong>, lay-out and installation of a primary network on the surface for the orientation of the connected machines (existing and planned) and increasing the accuracy of the tunnel network • Network densification by transferring the primary net into the single machine buildings. These networks are the basis for the mark out of the ideal positions of the supports and accelerator components (accuracy ± 1-2 mm) and the pre-alignment. 167
