  A control system for operating the future FAIR (Facility for Antiproton and Ion Research) accelerator complex is being developed at GSI. One of its core components is the settings management system. At CERN, settings management and data supply for large parts of the CERN accelerator complex is done using the LSA (LHC Software Architecture) framework. Several concepts of the LSA framework already fit the FAIR requirements: Generic structures for keeping accelerator data; modular design; separation between data model, business logic and applications; standardized interfaces for implementing the physical machine model. An LSA test installation was setup at GSI and first tests were performed controlling the GSI synchrotron SIS18 – already applying the new system to the existing facility. These successes notwithstanding, there are issues resulting from conceptual differences between CERN and FAIR operations. CERN and GSI have established a collaboration to make LSA fit for both institutes, thereby developing LSA into a generic framework for accelerator settings management. While focussing on the enhancements that are necessary for FAIR this paper presents also key concepts of LSA.

WEPL020 EPICS applications in the control of SPES Target Laboratory controls, target, power-supply, diagnostics 67

  The project of a new facility for the Selective Production of Exotic Species (SPES) has started at LNL. Radioactive ions will be produced by impinging an UCx target by a 70MeV, 200μA proton beam delivered by a commercial cyclotron. Then, the unstable ions will be accelerated by injecting them into the LNL superconducting LINAC. The construction of Target and Ion source prototype is at an advanced stage and, after more than two years spent in its construction, preliminary extraction tests were carried out with non-radioactive beams. The control of Target instrumentation is based on EPICS; we describe here the basic choices on hardware and software tools on both IOC and client side and give a brief description of last developments.

THPL020 Control and Acquisition Software Complex for TBTS Experiments controls, target, vacuum, simulation 168
 
  • A. Dubrovskiy
    CERN, Geneva
  The Two Beam Test Stand (TBTS) is a test area in the CLIC Test Facility (CTF) to demonstrate the high power RF extraction and acceleration at a high accelerating gradient, which are feasibility issues for the Compact Linear Collider (CLIC) project. In order to achieve an efficient data collection, an acquisition and logging software system was developed. All year round these systems store the main parameters such as beam position, beam current, vacuum level, pulse length etc. For predefined events they also gather and store all information about the last several pulses and the machine status. A GUI interface allows from anywhere to plot many logged characteristics at a maximum of 10 minutes delay, to go though all events and to extract any logged data. A control interface configures actions and long-term control procedures for conditioning accelerating structures. The flexible configuration of the logging, the acquisition and the control systems are integrated into the same GUI. After two years operation the critical components have shown highly fault-tolerant. Logging data are used for physic researches.  
 
FRCOMA02 FLASH DAQ Data Management and Access Tools controls, linac, laser, free-electron-laser 195

  The Free Electron Laser in Hamburg (FLASH) at DESY is a user facility for the photon science community. It produces laser light of short wavelengths from the extreme ultraviolet down to soft X-rays. To study, monitor and document the machine performance and parameters and also to collect the results of the experiment measurements, a fast data acquisition (DAQ) system has been developed. Having above 1000 linear accelerator diagnostics channels collected by the DAQ currently results in a data rate of ~100MB/s. The large amount of data requires corresponding data storage and management to enable an efficient data retrieval. This paper will focus on the data paths, storage and bookkeeping. A number of tools provided for the users to work with DAQ data will be described. The current status of the achieved performance in the data storage and retrieval will be covered as well.
