24 June 2010For 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. Prior to this, there was a five-month machine upgrade, above all with a significant improvement of the superconducting linear accelerator and the installation of a seeding experiment together with the University of Hamburg.

17 June 2010The University of Hamburg and DESY have won a shared Alexander von Humboldt professorship for the development of accelerators and particle physics. The renowned award goes to Professor Brian Foster, currently head of Particle Physics at the University of Oxford in the United Kingdom, the Alexander von Humboldt Foundation and the Federal Ministry of Education and Research announced today. Assuming successful conclusions to negotiations, Foster will receive up to 5 million Euros over a period of five years to fund research into the development and realisation of acceleration technologies for particle physics and continued analysis of data from DESY's flagship accelerator, HERA.

Barbara Warmbein | 10 June 2010I don't usually start stories for ILC NewsLine with the word 'I'. This time I have to make an exception, because for a change I was not merely a spectator and communicator of science, but a facilitator (of sorts). One of the actors in something both very mundane and very exciting: transporting scientific equipment from one lab to another. On Sunday 30 May, the EUDET beam telescope was brought from DESY to CERN, and I was one of its (three) drivers.

Barbara Warmbein | 25 February 2010Sometimes detector projects that are still at a planning stage can tell detector projects that are already taking data what hardware to use. This is certainly the case when the R&D project has been using, trying and testing a technology that the 'old hand' is considering for its upgrade: a relatively new type of sensor called Silicon Photo Multiplier, or SiPM, developed in Russia. A meeting brought experts from all areas that use SiPMs together at DESY in Hamburg, Germany, for two days earlier this week.

Rika Takahashi | 28 January 2010Four superconducting accelerating cavities have been successfully assembled at KEK’s Superconducting RF Test Facility (STF). From 14 to 22 January, the assembly team of technical staff from DESY and Fermilab visited KEK, and completed cavity-string assembly work in the STF cleanroom, making a wonderful start for S1 global, a crucial system test towards realising the International Linear Collider.

12 November 2009When you plan to move and try to find helpers, they often ask: to which floor? If the DESY people working in the detector lab would depend on the help of friends, they would have difficulties to find volunteers because the answer would be: seventh floor! Everything has to be transported from the ground floor to deep down underground. The HEP groups' detector lab moves from hall 5 to HERA hall west. In order to make room the electronics hut of the still present HERA-B detector was dismantled.

Barbara Warmbein | 29 October 2009The idea sounds simple enough: collect all the data that exist in the world on cavities – nine-cell TESLA-style cavities, to be precise – including all tests, manufacturers and achieved gradients and merge it into a common format so that all cavity professionals around the world can extract the data they need to compare cavity performance and learn. Anyone who has ever set up a database and tried to merge existing data sets into one knows: it's not that easy. However, the ILC's accelerator experts have just decided that they will all use a database system developed by DESY to set up the world's first global cavity database.

Barbara Warmbein | 24 September 2009The last two weeks were two of the most important (and intense) weeks for accelerator specialists working on the ILC. After a long period of preparation and a series of first tests, they have just finished a period of successfully running the superconducting linear accelerator FLASH at DESY under ILC-like conditions to demonstrate that a long train of electron bunches with high charge can be produced in and travel through the accelerator – and stay there, too. After the ILC-like run, which ended on Monday after long day and night shifts in the control room, FLASH will receive a major upgrade to improve capabilities and performance for the users of the laser light generated by FLASH.

Barbara Warmbein | 3 September 2009It takes vision to be able to image the transformation of one thing into another. Take a football field, for example. What are your associations – running, competition, goals, fun? And now imagine you want to build a new accelerator. What would you use the field for? The European XFEL team at DESY did not have to reflect for very long: acceleration, competition, goals? An accelerator module test facility of course! It’s only a small step to the next vision: an accelerator module test facility for the ILC…

Gerrit Hörentrup (DESY) | 27 August 2009When groups from different countries work together the usual procedure is to send the people to the machines they are working on. A team of engineers and technicians from DESY, Fermilab and KEK decided to do the exact opposite: they sent the machines to the people. On 3 August two machines constructed at DESY embarked on a voyage to Fermilab in the US.
