12th SC meeting at MAX IV, Lund, Sweden.

The 12th Steering Committee meeting of the Collaboration of European FEL and SPS Facilities took place on 26-27 September 2013 at MAX IV, Lund, Sweden.
After presenting recent developments, on-going activities and future plans at their facilities, the SC members discussed extensively the implications of the recent report of the Assessment Expert Group about the readiness for implementation of EuroFEL as a distributed research infrastructure according to the definition of ESFRI, as well as possibilities for EU funding based on the first informal draft of the H2020 Work Programme 2014-2015. It was agreed to give highest priority to strengthening the Collaboration and enhancing its visibility both at the European and international level.
The SC reviewed the on-going collaboration activities, including the expert groups on seeding and pulse length measurement, the white paper and the preparation of the Science at FELs conference 2014 at PSI on 14-17 September 2014. It was agreed to expand the pulse duration expert group with a sub-group on fs-timing and synchronization and to include a networking session for students at the Science@FELs 2014.


The Conceptual Design Report of CLARA test facility has been published

The Conceptual Design Report of the proposed new Free Electron Laser Test Facility, CLARA, has now been published by STFC Daresbury Laboratory.
This CDR describes an exciting and ambitious new accelerator test facility for the UK which will be capable of testing many 4th and 5th generation light source techniques and technologies. It is envisioned that CLARA will be dedicated to the production of ultra-short photon pulses of high-brightness coherent light. In order to achieve this vision, CLARA must be able to implement advanced techniques, such as laser seeding, laser-electron bunch manipulation, and femtosecond synchronisation. These can only be achieved by developing a state-of-the-art accelerator with the capability to drive current FEL designs. CLARA is therefore of direct relevance to the wider international accelerator community and will also ensure that the UK has all the skills required should it choose to develop its own future FEL facility.

Members of the Steering Committee during the 8th meeting at INFN Frascati, Italy

8th Steering Committee meeting of the Collaboration of European FEL and SPS Facilities, 14 – 15 March 2013 in Frascati, Italy

The Steering Committee of the Collaboration of European FEL and SPS Facilities and FELnet/CALIPSO members met from the 14 – 15th March 2013 at INFN, Frascati, Italy. During this meeting aimed at discussing the status of the Collaboration and planning future activities, it was unanimously agreed to admit the IR-FELs (CLIO, FELBE and FELIX) from FELnet/CALIPSO, as full members of the Collaboration, bound by the MoU signed on 31st May 2012.

The meeting began with members giving highlights on recent and on-going developments at their facilities – from progress in planning, construction, upgrade of existing facilities to experimental designs and user activities. It was observed that there is a strong momentum in the development of FEL science in Europe. However, there is a greater need to jointly coordinate such efforts in order to provide efficient and cost effective services to the user communities.

Two newly established expert groups on pulse length measurement and seeding schemes bringing together experts from the Collaboration, presented first ideas for joint technical developments. These groups are also open to external experts who want to contribute to the topics.

In addition to the technical collaboration activities, the members plan the publication of a white paper on European FEL science. The concept of this white paper was discussed and it was decided that the paper will include the science case for the complete European research infrastructure of free electron lasers comprising the European XFEL and all national FEL facilities. The white paper is planned to be published by March 2014.

The second day of the meeting focussed on the establishment of EuroFEL as legal entity. A draft statute of EuroFEL as an AISBL (association international sans but lucrative) submitted by DESY was examined and it is currently being examined by the legal representatives of the interested facilities.

Activities planned for 2014 are the 2nd Science at FEL conference, to be organized as a satellite to the FEL conference in Basel, and an FEL school for Ph.Ds. and Postdocs at MAX IV Laboratory.

Representatives of the ten research organisations sign the MoU

Establishment of European Free-Electron Laser Collaboration

Partner institutions of the IRUVX-PP project together with the European XFEL agreed on a close long-term collaboration in the field of free-electron lasers and accelerator-based short-pulse sources. With combined efforts, the technologies and methods for operating and using these novel research facilities will be further developed and implemented, thus creating a unique European research infrastructure of short-pulse light sources, offering optimal experimental conditions for a wide range of scientific applications.
With the signing of the agreement on 31 May 2012, a total of ten research institutions from France, Germany, Great Britain, Italy, Poland, Sweden and Switzerland express their interest to promote research with free-electron lasers. After the joint signature, the representatives of the ten institutions nominated Dr. Josef Feldhaus (DESY) as first chairman of the collaboration’s steering committee for the next three years and discussed the first action items of the new collaboration.

3rd Annual IRUVX-PP Meeting on 21 – 23 March in Berlin

With a three-day meeting in Berlin, the EU project IRUVX-PP– the “Preparatory Phase of the EuroFEL Consortium” of the ESFRI roadmap 2006 coordinated by DESY – was brought to an end. The event was hosted by Helmholtz-Zentrum Berlin, one of the project partners.

The participating scientists (117) made a very positive résumé: in the project phase of three years, new networks were created on different levels between the partners. This does not only include technical innovations but also the optimal use of the facilities, coordinated training and exchange of personnel, and improved internal and external communication.

The perfectly organised meeting started on a sunny Monday with the facilities’ status reports on the national FEL projects. A lively panel discussion on the afternoon with the topic future „European collaboration of FEL and SPS facilities“ rounded off the first day. The discussion made evident that the current collaborations in FELs science and technology need to be strengthened.

On Tuesday, the work package leaders summarised their project results and presented highlights from three years of project work, see details:

On Tuesday afternoon, working groups elaborated proposals for further activities. At first, these will be promoted and funded by the participating centres. Parallel to this, there was a satellite meeting dealing with “Timing and Synchronisation”. Scientists from the partner facilities presented the latest developments, results and experiences.

The last meeting day focused on recent highlights from FEL science and technology developments under the motto “EuroFEL provides access to cutting-edge technology”.

“With IRUVX-PP, we created the basis for a firm and long-term collaboration, and I hope that the obtained results will convince the decision makers”, said coordinator Josef Feldhaus. The future collaboration shall soon be sealed with a memorandum of understanding. Negotiations on this are currently being carried out among the directors of the participating institutes and includes the director of European XFEL too.


EuroFEL Workshop on Photocathodes for RF guns, INFN of Lecce, Italy

From 1-2 March 2011, the EuroFEL “Workshop on Photocathodes for RF guns” took place at the Physics Department of the University of Salento. This workshop was held in the frame of Workpackage 3 of the IRUVX-PP project and organised by the support of National Institute of Nuclear Physics (INFN). Over 40 researcher experts in these fields took part to this workshop coming from several international research institutes. In particular L. Cultrera (Cornell University), D. Dowell (SLAC), F. Hannon (Jefferson Laboratory), and X. J. Wang (BNL) attended from the United States.

Despite of the short time, a number of interesting topics was faced such as: Photoemission theory (derivation of QE and thermal emittance, cathode engineering); Photocathode growth and preparation (metal and semiconducting thin films and metal bulk surface treatments); Photoelectrons characterisations (quantum efficiency, thermal emittance, dark current); Photocathode lifetime (observations of pollution, RF conditioning influence, UV laser interaction with residual gas, etc.); Experience on photocathodes; Cathode cleaning techniques (laser cleaning, annealing, ozone gas,etc.); Advanced photoelectron sources (carbon nanotubes, spindt field emitter, ultracold electron sources); New material for photocathodes: high QE, cathodes for IR or green laser light, and for SC guns.

The organisers were very proud to organise this workshop which was a great tool for discussions and for exchange ideas in photocathode R&D. The organisers: Giuseppe Penco, Antonella Lorusso & Siegfried Schreiber


Directors Meeting at PSI

Representatives of the labs participating in the IRUVX-PP project met from 25 to 26 November at Paul Scherrer Institute in Switzerland. The main
goal of the meeting was to decide on the procedure, the areas and the framework of their future collaboration. IRUVX-PP, the preparatory phase
for EuroFEL, is to finish end of March 2011. The Directors of DESY, Elettra, HZB, INFN, Max-Lab, PSI and STFC agreed on drawing up a Memorandum of Understanding defining the areas of activities in which they want to collaborate in the future.

The MoU is to be signed by the lab directors shortly before the end of the IRUVX-PP project and will define the framework of the collaboration. The
scientists of the IRUVX-PP project are now encouraged to propose precise activities and projects that they would like to pursue after IRUVX-PP, so
that the most propelling projects can be continued in the coordinated and collaborative way that has been successfully initiated in the individual workpackages.

New experiments need new diagnostics

FELs are opening a fascinating new world of opportunities for photon science. They are providing light pulses of a coherence, brightness and shortness that even a few years ago scientists weren’t able to dream of. But with the new opportunities also new challenges are arising: How to handle and diagnose a light pulse that is a thousand times shorter and a billion times brighter than ever before? Industrial suppliers for today’s synchrotron sources are not able to provide beam line transport systems with the required thermal resistance and spatial accuracy to exploit FELs; they don’t even have the metrology to measure them. New materials, new techniques and new ideas are necessary.

End of June, about 85 scientists from 33 current and future FEL labs and industrial participants met at DESY in Hamburg for the first “EuroFEL Workshop on Photon Beamlines and Diagnostics” which was organised by the workpackages 3 & 7 of the IRUVX-PP project. The aim was to discuss new ideas which arise in the different laboratories, and to start joining the efforts for developing diagnostic systems and metrology. Perspectives of entirely new R&D efforts were presented, for example multilayer mirrors that are able to compress or expand the FEL beam or which can be used for soft X-ray polarimetry techniques. Wave front sensing, another intensively discussed topic, is one of the most promising approaches to optimise FEL beam transport systems and might be used for active or adaptive optics. “It was great to see the participants in intense discussions and making plans for joint projects,” says DESY’s Kai Tiedtke. “The people have amazing new ideas and approaches for the challenges of the FELs.” After three days of presentations and discussion, the participants returned to their labs with the clear wish that this dedicated FEL workshop should mark the start of a series.

IRUVX-PP meets industry

As part of the WP6 “Collaboration with industry”, the IRUVX-PP consortium organised a workshop “IRUVX-PP meets industry” on 1 March 2010 in Döllnsee near Berlin in connection with the 2nd IRUVX-PP Annual Meeting. There were 85 participants from industry, scientists and engineers from the partner institutes and 20 industrial exhibitors. The objective of the workshop was to open a dialogue with industry and focus on key industries for the setting up of new FEL facilities. Therefore the aim was to provide information to industry about required specification for realisation of advanced components and systems, required R&D collaboration with industry, outline of industry’s involvement and opportunities and give examples of collaboration with industry and technology transfer from both an institute perspective and from an industry perspective.

Common technical needs for construction of FELs have initially been identified in the areas of photon and e-beam diagnostics, X-ray optics, laser systems, synchronisation and control systems. Other areas, such as advanced undulator concepts, detector development, cryogenic modules and superconducting RF technology, will be addressed in future workshops. Very positive feedback has been received from both, the industry and engineers with the main feedback from industry indicating that networking with individual facilities is difficult and there is a distinct advantage in linking with EuroFEL with experts being present from all over Europe.
