    Opis:
    Protein crystallography, the main experimental method of structural biology, has undergone in the recent past three revolutionary changes leading to its unexpected renaissance. They were connected with (i) the introduction of synchrotron radiation sources for X-ray diffraction experiments, (ii) implementation of Se-Met multiwavelength anomalous diffraction (MAD) for phasing, and (iii) initiation of structural genomics (SG) programs. It can be foreseen that in the next 10-15 years protein crystallography will continue to be in this revolutionary phase. We can expect not only an avalanche of protein crystal structures from SG centers, but also attacking of more demanding projects, such as the structure of membrane proteins and of very large macromolecular complexes. On the technological front, the introduction of X-ray radiation from free-electron lasers will revolutionize the experimental possibilities, making feasible even the imaging of single molecules and of intact biological cells.

    Opis:
    The most powerful now in the world, American X-ray laser LCLS (Linac Coherent Light Source), has been working as a research and user facility since 2009. It is further developed to LCLS II machine at the Stanford National Accelerator Laboratory SLAC in Menlo Park CA. In a certain sense, LCLS II is a response to the EXFEL machine and a logical extension of LCLS. All these machines are light sources of the fifth generation. EXFEL is expected to open user facility in 2016, at a cost of over 1 mld Euro. LCLS II, which design started in 2010, will be operational in 2017. The lasers LCLS, LCLS II and EXFEL use SASE and SEED methods to generate light and are powered by electron linacs, LCLS by a warm one, and EXFEL by a cold one. The linacs have energies approaching 20 GeV, and are around 2 - 3 km in length. EXFEL linac uses SRF TESLA microwave cavity technology at 1,3 GHz. A prototype of EXFEL was FLASH laser. SLAC Laboratory uses effectively over 50 years experience in research, building and exploitation of linear electron accelerators. In 2009, a part of the largest 3 km SLAC linac was used to build the LCLS machine. For the LCLS II machine a new infrastructure is build for two new laser beams and a number of experimental stations. A number of experts and young researchers from Poland participate in the design, construction and research of the biggest world linear and elliptical accelerators and FEL lasers like LCLS (Stanford), EXFEL (DESY) and CEBAF (JLab), and a few more. The paper concentrates on the development state-of-the-art of large laser infrastructure and its global and local impact, in the competitive world of R&D. LCLS infrastructure implications in Poland are considered.

    Opis:
    Gamma and neutron radiation is produced during the normal operation of linear accelerators like Free-Electron Laser in Hamburg (FLASH) or X-ray Free Electron Laser (X-FEL). Gamma radiation cause general degeneration of electronics devices and neutron fluence can be a reason of soft error in memories and microcontrollers. X-FEL accelerator will be built only in one tunnel, therefore most of electronic control systems will be placed in radiation environment. Exposing control systems to radiation may lead to many errors and unexpected failure of the whole accelerator system. Thus, the radiation monitoring system able to monitor radiation doses produced near controlling systems is crucial. Knowledge of produced radiation doses allows to detect errors caused by radiation, schedule essential replacement of control systems and prevent accelerator from serious damages. The paper presents the project of radiation monitoring system able to monitor radiation environment in real time.

    Opis:
    The Advanced Telecommunications Computing Architecture (ATCA) standard describes a powerful and efficient platform. With multiple integrated solutions like redundancies and intelligent control mechanisms this technology is characterized with reliability estimated at the level of 99.99999 percent. These features make the standard perfect for use in projects like the Free Electron Laser in Hamburg (FLASH) and the X-ray Free Electron Laser (X-FEL) in order to help them meet the requirements of high availability and reliability. The ATCA standard incorporates advanced control systems defined in the Intelligent Platform Management Interface (IPMI) specification as one of the key elements. The entire ATCA implementation retains its functionality as long as the IPMI remains operational. The complexity level of the application increases, which results in preparing it to run and debugging being more difficult to perform. At the same time, only scrupulous elimination of any kind of possible deficiencies can enable the ATCA implementation to offer the desired level of reliability. Thus, diagnostics become crucial, which creates a need for additional tools performing these tasks during the preparations of both hardware and software for the ATCA application. The paper presents application aiding in development of the prototype Carrier Board by enabling the user of external PC station to perform diagnostic and control activities over the Board. It helps in examining all its components at the stage of running the Board, as well as in further operation analysis.

    Opis:
    Free electron laser FELs are built in Europe mainly as nondependent infrastructures, or as a development of synchrotron ones. They are constructed mainly in centres which have considerable experience with synchrotron light sources of the third generation like DESY, Trieste, INFN, etc. Advances in very energetically efficient superconducting linear accelerators for electron beams, like TESLA type, caused an abrupt development of FEL machines all over Europe. New generation of FELs emits light beam of extreme intensity, good parameters, in IR, VIS, UV, EUV and X-ray spectral regions. The machine construction teams comprise also of young active researchers from Poland. In particular, these is a considerable participation of M.Sc. and Ph.D. students from Warsaw University of Technology at building of FLASH I, FLASH II, and EXFEL machines. Unique experiences gathered at work with these large experiments result in development of these young teams, and their further engagement in new initiatives: laser, laser - accelerator, inertial, plasma, plasma - energy, etc. This is what we observe with satisfaction. However, due to the lack of large research infrastructures in Poland, we are not members of the infrastructure owner clubs. Our young researchers may take part in the initiatives only indirectly as members of cooperative teams from the leading countries. As a further consequence, there is also a confined access of Polish laser and accelerator researchers to some kinds of European infrastructure development projects now under realization within the H2020.

    Opis:
    The Advanced Telecommunications Computing Architecture (ATCA) standard describes a powerful, high performance platform. Its implementation has been considered among candidates for a base of the control system of the X-ray Free Electron Laser (X-FEL), which is being built at Deutsches Electronen-Synchrotron (DESY) in Hamburg, Germany. The Low Level Radio Frequency (LLRF) control system is designed as a set of ATCA Carrier Boards. Each Carrier Board hosts an Intelligent Platform Management Controller (IPMC), which is developed in compliance with the PICMG specifications. IPMC is responsible for management and monitoring of components installed on Carrier Boards and pluggable Advanced Mezzanine Card (AMC) modules. The ATCA Shelf Manager is the main control unit of a single ATCA shelf, responsible for power management, fan modules and Carrier Boards installed in ATCA shelf. It provides a set of control and diagnostic capabilities regarding the shelf and its sub-modules. These capabilities are available for operators and can be used by higher level applications. This publication presents a software component intended to support management and supervision of the ATCA shelf and its sub-modules, including Carrier Boards with AMC modules. The application provides enhanced mechanisms of control and allows to acquire detailed information regarding status and parameters of crucial devices (e.g. power supply voltages, temperatures, presence of reference clocks). The information supplied from Shelf Manager combined with graphical user interface of the application provides visual representation of selected system components and contributes towards efficient control and supervision of Carrier Boards and entire ATCA-based platform.
