EuroFEL is part of the ESFRI Roadmap since 2006. The preparatory phase of EuroFEL
(IRUVX-PP) prepared the establishment of the EuroFEL Consortium to link FEL &
SPS facilities in Europe closer together. IRUVX-PP has been funded by the European
Commission under FP7 from April 2008 to March 2011.
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.
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.

On the 26 and 27th June 2013, the kick-off meeting of the Seeding Schemes Expert Group took place at Synchrotron SOLEIL, France. The meeting was chaired by the coordinator of this group – Luca Giannessi and brought together participants from Elettra, European XFEL, DESY, INFN, MAX IV, SOLEIL and STFC. Various topics were discussed and a draft work plan for collaborative activities prepared . This Expert Group is one of the activities established by the Collaboration of European FEL and SPS Facilities to strengthen technical collaboration between the various facilities.
European XFEL underground construction completed
An important milestone was reached on Germany’s largest science construction site: the underground civil engineering work for the X-ray laser European XFEL has been completed, and the underground construction is almost finished. About 300 guests from politics, academia, administration, and business gathered to celebrate and visit the underground facilities in Schenefeld.
Kick-off meeting: Pulse Length Measurement Expert Group
The kick-off meeting of the Pulse Length Measurement Expert Group took place at DESY Hamburg, from the 10-11 June 2013. This group was established by the Collaboration of European FEL and SPS Facilities to foster joint research activities.
This initial meeting gave an opportunity to participants to learn about on-going activities and interests of the various facilities on pulse length measurement from which common topics of interest for joint research activities will be identified and work plans developed.
Over 20 participants including representatives from Elettra, European XFEL, PSI, SOLEIL and DESY attended the meeting. Stefan Düsterer from DESY is the coordinator of this Expert Group.
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.
The beam line FERMI FEL-2 has generated its first coherent photons
On October 11, 2012 the beam line FERMI FEL-2 has generated its first coherent photons. This is the first experimental demonstration of a seeded free electron laser configured as a two stages cascade operating in the "fresh bunch injection” mode, where the second stage is seeded by the light produced by the first stage. In this configuration the photons in the second stage are generated from a fresh portion of the electron bunch, which has not been heated by the seed of the first stage, overcoming the problem of the induced energy spread which limits the order of the harmonic conversion in a high-gain harmonic-generation seeded FEL.
The first commissioning experiments were done at a final wavelength of 14.4 nm in planar polarization. This wavelength is the result of an harmonic conversion to the 6th harmonic (43.3 nm) in the first stage and the 3rd harmonic in the second (i.e., 18th harmonic of the seed laser). The FEL pulse energy has been optimized to increase the flux to about 20-30uJ. Further tests at the final wavelengths of 10.8nm (4th harmonic conversion in the second stage) and 8.7 nm (5th harmonic conversion in the second stage) are in progress. The figure shows one of the single mode spectra obtained from FEL-2 at 14.4 nm.
DESY extends its Free Electron Laser FLASH - Start of construction work for FLASH II main tunnel
DESY's Free Electron Laser FLASH doubles its research capacity: in the beginning of August, the construction of the main tunnel section of the FLASH II extension project has started. The installation of a second FEL in the new 110-metre-long tunnel and the construction of a second experimental hall with room for six experimental stations are planned in 2013. First experiments should be possible by the end of 2014.
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.
3rd Annual IRUVX-PP Meeting on 21 – 23 March 2011 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.
Workshop on Photocathodes for RF Guns in 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.
First images of proteins and viruses caught with an X-ray laser
Experiments at LCLS show the scientific potential of X-ray Free Electron Lasers
It has been a dream of researchers for over a decade: image biological materials at high resolution using incredibly intense X-ray laser pulses. Calculations had long predicted that these blasts of X-rays would allow exquisite measurements of the molecular structure of biological objects, from samples too small to be studied by conventional methods. In the usual methods, X-ray images of materials are blurred out because the X-rays degrade the structure. Surprisingly, the proposed way to overcome this “radiation damage” is to use ultra-short pulses a billion times brighter than conventional sources. The pulses are so fast that the image is formed before the effects of the damage are felt.
Seeded coherent emission from FEL-1 measured by means of a fast photodiode located in the FERMI@Elettra experimental hall. The undulators were tuned at 43 nm. The green trace shows the time profile of a single pulse with the photodiode in saturation. The yellow trace shows a series o seeded FEL pulses being turned on (left) and off (center-right) by changing the superposition between SEED laser pulses and electron pulses.
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.
PSI scientists perform the worlds first hard X-FEL user experiment at SLAC
In October 2010, the commissioning phase of the X-Ray Pump-Probe experimental station at the Stanford LCLS source was finished. The very first user experiment in the hard x-ray range was carried out by a group of scientists from SLAC, the European XFEL and PSI under the lead of Christian David (PSI).
First lasing of the ALICE FEL at STFC Daresbury Lab
Good news from our UK partners: The Infra Red Free Electron Laser installed on the ALICE energy recovery accelerator at STFC Daresbury Laboratory lased for the first time on Saturday 23rd October 2010 at 16:35. Once established, the FEL lased for several hours at about 8 microns wavelength and appeared quite tolerant to the machine setting.
IRUVX-PP PrepGroup and Steering Commitee meetings at DESY
The members of the IRUVX-PP PrepGroup and the Steering Commitee held meetings at DESY in Hamburg on 3 and 4 November 2010. In the meeting the consortium partners intensively discussed the next steps in the process of setting up the future EuroFEL consortium as an ERIC. Additionally they prepared the Directors' Meeting in Villingen end of November 2010. The work package leaders reported on the status of the deliverables which are all progressing very well. The next PrepGroup and SC meeting will take place on 17-18 January 2011.
FLASH opens the view through the water window
The Free Electron Laser FLASH at DESY in Hamburg has set a new record: this weekend, the FLASH accelerator team operated the FEL with an electron energy of 1.25 Giga electronvolts, thus reaching a wavelength of 4.12 nanometres. For the first time FLASH has generated laser light in the so-called water window using the fundamental wavelength – so far this was only reached with laser harmonics.
Research Council decision to release funding for MAX IV in Sweden
The Swedish Research council has decided to release and make available the funding previously granted for the MAX IV project. The consequence is that it is now possible to start signing the first order of the accelerator system.

Directors’ Meeting at the Paul Scherrer Institut (PSI) in Villingen
From 25 – 26 November 2010 the directors/representatives of the participating research centres, DESY, Elettra, HZB, INFN, MAX-lab, PSI and STFC will meet at the Paul Scherrer Institut in Switzerland to discuss the foundation of the future EuroFEL consortium. The aim of the meeting is to sign a preliminary consortium agreement.
The sFLASH seeding test takes up operation
The most valuable good at FLASH is time. FLASH is more or less the universal prototype for X-ray Free Electron Lasers; therefore, many scientists compete for every minute on it. This is not only true for the users who have been served in routine operation since 2005, but also for accelerator physicists and developers who never run out of ideas on how to improve the facility. They keep upgrading FLASH under the critical eyes of the researchers’ world and show what this technology can do.
Lights on…. Inauguration of the SwissFEL Injector Test Facility
An important milestone for the realization of the new SwissFEL facility was reached on the 24th of August 2010, when the core of the new SwissFEL facility was set into operation at the Paul Scherrer Institute. Guest of Honour, Bundesrat Didier Burkhalter pressed the red button, and the SwissFEL Injector Test Facility produced its first electron beam. The Paul Scherrer Institute is one of the partners of the EuroFEL consortium. For more information see news from PSI .

End of June, about 85 scientist 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 and 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.
Record wavelength at FLASH – First lasing below 4.5 nanometres at DESY´s Free Electron Laser
The spectrum of the record laser pulse peaks at a wavelength of 4.45 nanometres. For the first time, FLASH produced laser light with a wavelength of 4.45 nanometres; thus, DESY’s Free Electron Laser for soft X-ray light considerably beat its previous record of 6.5 nanometres. At the same time, the peak intensity of single light pulses nearly doubled, with 0.3 millijoule.
A IRUVX-PP SC meeting was held at DESY in Hamburg on 17 June 2010 to concretise the planning for the 3rd project year.
The meeting topics were: reports from the workpackages and deliverables for the 3rd year, internal regulations for the future activity boards, internal regulations for the future EuroFEL activity boards and plannings for the transition phase to the EuroFEL consortium. Furthermore a concept to reach new users has been presented and discussed.
The next SC meeting will take place on 4 November.
