FLASH2020+ technical design phase started


Making FLASH brighter, faster and more flexible


The technical design phase of the FLASH2020+ project at DESY started with an internal virtual kick-off meeting. Over 270 participants mainly from DESY and the campus in Hamburg joined the project team online on 3 July 2020. Key topics were the upgrade project of the free-electron laser (FEL), scientific goals, the embedding at DESY and the international landscape, the project structure and its timeline over the next five years.

The FLASH2020+ project is based on the long history of FLASH at DESY, from its inception as a test facility for the TESLA project in the mid-90s of the last century to the worldwide first XUV to soft X-ray FEL user facility ten years later. With the FLASH2 project, it is now the first FEL that runs two independent undulator lines in parallel, again about ten years later.

In 2020, yet another ten years later, the project is right in time to make the next step forward with the facility where especially the external seeding and shorter pulses will enable new and unique scientific opportunities. The upgrade will keep FLASH at the forefront of science with FELs for the next decade, as highlighted by Edgar Weckert, director in charge for DESY Photon Science. The importance of the project for the DESY strategy to further advance DESY’s machines and to develop new technologies for future accelerators was stressed by Wim Leemans, the DESY director of the accelerator division. With such a project, DESY contributes also to the technical developments in FEL science and teaching of the next generation of scientists.

The FLASH2020+ project is be led by Enrico Allaria, who presented the project phases, timeline and structure. He is an expert from the FEL “FERMI” in Trieste (Italy) and has just started to work at DESY.

Kai and Albert

Kai Siegbahn was awarded the 1981 Nobel Prize in physics for “his contribution to the development of high-resolution electron spectroscopy”.
Albert Einstein received the 1921 Nobel Prize in physics for “his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect”.

10 years of SASE at FLASH

Back in 2005, early in the morning of January 14th, first SASE has been observed at DESY's newly installed VUV free-electron laser. The electron beam has been accelerated to 445 MeV corresponding to a wavelength of 32 nm. In summer 2005, the VUV-FEL turned into a user facility named FLASH.

The image shows the Spectrum of the first SASE signal measured in the early morning of January 14th, 2005.

Fifth user period started 24-Feb-2014 with its first beam time block

Coming out of a long shutdown to finish up the construction of the new beamline FLASH2, the fifth user period for beamline FLASH1 has started end of February with its first user block. Until April 2015, more than 5000 hours of user experiments are scheduled. Beam time will also be available for accelerator and photon beam line studies as well as for FLASH2 commissioning. FLASH2 saw first beam in March 2014 pushing the beam to the dump for the first time May, 23. Since then, FLASH2 is operated in parallel to FLASH1 whenever possible to finish up the commissioning of beam diagnostics and to refine beam optics. First SASE radiation at 40 nm has been seen on Aug 20, 2014. The next goal is to characterize the SASE radiation, to measure gain length for example for as many other wavelength.

The image shows a schematic layout of FLASH. Not to scale. The second beamline, FLASH2, is being commissioned.
