  The European XFEL is a 3.4km long X-ray Free Electron Laser in the final construction and commissioning phase in Hamburg. It will produce 27000 bunches per second at 17.5GeV. Early 2015 a first electron beam was produced in the RF-photo-injector and the commissioning of consecutive sections is following during this and next year. The huge number and variety of devices for the accelerator, beam line, experiment, cryogenic and facility systems pose a challenging control task. Multiple systems, including industrial solutions, must be interfaced to each other. The high number of bunches requires a tight time synchronization (down to picoseconds) and high performance data acquisition systems. Fast feedbacks from front-ends, the DAQs and online analysis system with a seamless integration of controls are essential for the accelerator and the initially 6 experimental end stations. It turns out that the European XFEL will be the first installation exceeding 2500 FPGA components in the MicroTCA form factor and will run one of the largest PROFIBUS networks. Many subsystem prototypes are already successfully in operation. An overview and status of the XFEL control system will be given.

  PID (Proportional, integral and derivative) is the most used feedback control algorithm in the process control industry. Despite its age, its simplicity in terms of deployment and its efficiency on most of industrial processes allow this technique to still have a bright future. One of the biggest challenges in using PID control is to find its parameters, the so-called tuning of the controller. This may be a complex problem as it mostly depends on the dynamics of the process being controlled. In this paper we propose a tool that is able to provide the engineers a set of PID parameters in an automated way. Several auto-tuning methods, both in open and close loop, are selectable and others can be added as the tool is designed to be flexible. The tool is fully integrated in the UNICOS framework and can be used to tune multiple controllers at the same time.

  Almost 200 controls applications, in domains like LHC magnet protection, cryogenics and vacuum systems, cooling-and-ventilation or electrical network supervision, have been developed and are currently maintained by the CERN Industrial Controls Group in close collaboration with several equipment groups. The supervision layer of these systems is based on the same technologies as 400 other systems running in the LHC Experiments (e.g. WinCC Open Architecture, Oracle). During the last two-year LHC Long Shutdown 1, the 200 systems have been successfully migrated from a file-based archiver to a centralized infrastructure based on Oracle databases. This migration has homogenized the archiving chain for all CERN systems, and at the same time has presented a number of additional challenges. The paper presents the design, the necessary optimizations and the migration process that allowed us to meet unprecedented data-archiving rates (unachievable for the previously used system), and liaise with the existing long-term storage system (LHC LoggingDB) to assure data-continuity.

  EAST (Experimental Advanced Superconducting Tokamak) is the first full superconducting experimental Tokamak fusion device in the world which has been carried out ten campaigns since its implementation at the end of 2005. The cryogenic control system for EAST was designed based on DeltaV DCS of Emerson Corporation which has been in operation for the same time period and has been proved to be safe and stable. However, Manny control components have been running beyond the expected lifetime gradually. Many problems from control system have affected the cryogenic system reliability. This paper presents the current status and upgrade solutions of the cryogenic control system of EAST.

THHD3O08 Upgrades to the Infrastructure and Management of the Operator Workstations and Servers for Run 2 of the CERN Accelerator Complex controls, network, operation, site 1

  The Controls Group of the CERN Beams Department provides more than 400 operator workstations in the CERN Control Centre (CCC) and technical buildings of the accelerators, plus 300 servers in the server room (CCR) of the CCC. During the long shutdown of the accelerators that started in February 2013, many upgrades were done to improve this infrastructure in view of the higher-energy LHC run. The Engineering Department improved the electrical supply with fully redundant UPS, on-site diesel generators and for the CCR, water and air cooling systems. The Information Technology Department increased network bandwidth for the servers by a factor of 10 and introduced a pilot multicast service for the video streaming of the accelerator status displays and beam cameras. The Controls Group removed dependencies on network file systems for the operator accounts they manage for the Linacs, Booster, PS, ISOLDE, AD, CTF3, SPS, LHC and cryogenics. It also moved away from system administration based on shell scripts to using modern tools like version-controlled Ansible playbooks, which are now used for installation, day-to-day re-configuration and staged updates during technical stops.
