  The construction of the X-ray free electron laser facility (SACLA) in SPring-8 started in 2006. After 5 years of construction, the facility completed to accelerate electron beams in February 2011. The main component of the accelerator consists of 64 C-band RF units to accelerate beams up to 8GeV. The beam shape is compressed to a length of 30fs, and the beams are introduced into the 18 insertion devices to generate 0.1nm X-ray laser. The first SASE X-ray was observed after the beam commissioning. The beam tuning will continue to achieve X-ray laser saturation for frontier scientific experiments. The control system adopts the 3-tier standard model by using MADOCA framework developed in SPring-8. The upper control layer consists of Linux PCs for operator consoles, Sybase RDBMS for data logging and FC-based NAS for NFS. The lower consists of 100 Solaris-operated VME systems with newly developed boards for RF waveform processing, and the PLC is used for slow control. The Device-net is adopted for the frontend devices to reduce signal cables. The VME systems have a beam-synchronized data-taking link to meet 60Hz beam operation for the beam tuning diagnostics. The accelerator control has gateways to the facility utility system not only to monitor devices but also to control the tuning points of the cooling water. The data acquisition system for the experiments is challenging. The data rate coming from 2D multiport CCD is 3.4Gbps that produces 30TB image data in a day. A sampled data will be transferred to the 10PFlops supercomputer via 10Gbps Ethernet for data evaluation.

FERMI@Elettra is a new 4th-generation light source based on a seeded Free Electron Laser (FEL) presently under commissioning in Trieste, Italy. It is the first seeded FEL in the world designed to produce fundamental output wavelength down to 4 nm with High Gain Harmonic Generation (HGHG). Unlike storage ring based synchrotron light sources that are well known machines, the commissioning of a new-concept FEL is a complex and time consuming process consisting in thorough testing, understanding and optimization, in which a reliable and powerful control system is mandatory. In particular, integrated shot-by-shot beam manipulation capabilities and easy to use high level applications are crucial to allow an effective and smooth machine commissioning. The paper reports the status of the control system and the experience gained in two years of alternating construction and commissioning phases.

  The Free Electron Laser (SwissFEL) Test Facility is an important milestone for realization of a new SwissFEL facility. The first beam in the Test Facility was produced on the 24th of August 2010 which inaugurated the operation of the Injector. Since then, beam quality in various aspects has been greatly improved. This paper presents the current status of the Test Facility and is focused on the control system related issues which led to the successful commissioning. In addition, the technical challenges and opportunities in view of the future SwissFEL facility are discussed.

TUDAUST04 Status of the Control System for the European XFEL 597
  • K. Rehlich
    DESY, Hamburg, Germany
  DESY is currently building a new 3.4 km-long X-ray free electron laser facility. Commissioning is planned in 2014. The facility will deliver ultra short light pulses with a peak power up to 100 GW and a wavelength down to 0.1 nm. About 200 distributed electronic crates will be used to control the facility. A major fraction of the controls will be installed inside the accelerator tunnel. MicroTCA was chosen as an adequate standard with state-of-the-art connectivity and performance including remote management. The FEL will produce up to 27000 bunches per second. Data acquisition and controls have to provide bunch-synchronous operation within the whole distributed system. Feedbacks implemented in FPGAs and on service tier processes will implement the required stability and automation of the FEL. This paper describes the progress in the development of the new hardware as well as the software architecture. Parts of the control system are currently implemented in the much smaller FLASH FEL facility.

TUDAUST05 The Laser MegaJoule Facility: Control System Status Report 600

  The French Commissariat à l'Energie Atomique (CEA) is currently building the Laser MegaJoule (LMJ), a 176-beam laser facility, at the CEA Laboratory CESTA near Bordeaux. It is designed to deliver about 1.4 MJ of energy to targets for high energy density physics experiments, including fusion experiments. LMJ technological choices were validated with the LIL, a scale 1 prototype of one LMJ bundle. The construction of the LMJ building itself is now achieved and the assembly of laser components is on-going. A Petawatt laser line is also being installed in the building. The presentation gives an overview of the general control system architecture, and focuses on the hardware platform being installed on the LMJ, in the aim of hosting the different software applications for system supervisory and sub-system controls. This platform is based on the use of virtualization techniques that were used to develop a high availability optimized hardware platform, with a high operating flexibility, including power consumption and cooling considerations. This platform is spread over 2 sites, the LMJ itself of course, but also on the software integration platform built outside LMJ, and intended to provide system integration of various software control system components of the LMJ.

The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory is a stadium-sized facility that will contains a 192-beam, 1.8-Megajoule, 500-Terawatt, ultraviolet laser system together with a 10-meter diameter target chamber with room for multiple experimental diagnostics. NIF is the world’s largest and most energetic laser experimental system, providing a scientific center to study inertial confinement fusion (ICF) and matter at extreme energy densities and pressures. NIF’s laser beams are designed to compress fusion targets to conditions required for thermonuclear burn. NIF is operated by the Integrated Computer Control System (ICCS) in an object-oriented, CORBA-based system distributed among over 1800 front-end processors, embedded controllers and supervisory servers. In the fall of 2010, a set of experiments began with deuterium and tritium filled targets as part of the National Ignition Campaign (NIC). At present, all 192 laser beams routinely fire to target chamber center to conduct fusion and high energy density experiments. During the past year, the control system was expanded to include automation of cryogenic target system and over 20 diagnostic systems to support fusion experiments were deployed and utilized in experiments in the past year. This talk discusses the current status of the NIC and the plan for controls and information systems to support these experiments on the path to ignition.
