Globetrotters made of niobium

| 13 October 2011 The European XFEL X-ray laser in Hamburg will use accelerator modules of the newest generation. These high-tech devices are operated using superconducting technology at temperatures similar to those in outer space. The concept was developed and brought to practical application by the international TESLA collaboration, led by DESY. Category: Around the World | Tagged: ,

Virtual tunnel

22 September 2011 DESY's Information Management, Processes, Projects (IPP) group continued their design integration activities for the ILC and managed to automatically generate simple three-dimensional models from lattice files, obtaining a 3-D model of the entire accelerator. Tunnel and infrastructure models can be added where available to get an early preview of the facility. More images can be seen at the LCWS11 conference in Granada.

Humboldt Professor Brian Foster

15 September 2011 Brian Foster, Global Design Effort European Regional Director, recently began his tenure at DESY and the University of Hamburg as a recipient of the Alexander von Humboldt professorship. View this seven-minute video to learn about his research plans at DESY, the University and for the ILC. Category: Video of the week | Tagged: ,

Light through the wall – take 2

| 15 September 2011 DESY’s ALPS experiment aims high by searching low, looking for lightweight particles in the low-energy range. The lightweight particles could clue us into the nature of dark matter or dark energy, and ALPS is being upgraded to make more precise measurements than it could before.

Summer students of science

18 August 2011 This summer 81 students of 19 different nationalities joined in the day-to-day work of research groups at the DESY Laboratory in Hamburg and Zeuthen (Berlin), participating in different activities. An introductory talk about the ILC is included in this year's programme. Category: Image of the week | Tagged: ,

TULA tunnels through

11 August 2011 The tunnel boring machine TULA (TUnnel for LAser) squeezed through a large hole in the wall of the injector building of the European XFEL facility. The hole, only 40 centimetres wider than the colossus that is TULA, made for a challengingly tight fit. TULA, which started 7 July 2010 at the European XFEL construction site in Schenefeld (Schleswig-Holstein), arrived a couple of days ago at the DESY site in Hamburg. In 13 months it has completed three tunnels with a total length of 3084 metres of the tunnel system, including the 2.1-kilometre-long linac tunnel. The second tunnel boring machine AMELI is still on its way to dig the (slightly thinner) rest of the nearly 6-kilometre long European XFEL tunnel system. TULA is 6.17 metres in diameter and 71 metres long, weighs 550 tonnes and costs 18 million Euros. Category: Image of the week | Tagged: , ,

Good gradients in seconds flat

| 4 August 2011 A stable particle beam needs a trouble-free path on its way to high energies, and that means providing it with a smooth gradient to ascend. A team of scientists at Fermilab has arrived at a way to control accelerating cavities so they can give particle beams exactly that – a tilt-free path to collision.

Up in the air

21 July 2011 The PCMAG – the magnet of the large prototype time projection chamber – will travel from DESY in Germany all the way to KEK in Japan. Before the magnet can begin its journey it must be properly wrapped and lifted out of the DESY test beam facility. Have a save trip PCMAG! Category: Image of the week | Tagged: , , , ,

Achieving cavity resonance

| 7 July 2011 Keeping accelerating cavities tuned to the right frequency requires continual, gentle hammering by a little device called a piezoelectric tuner. DESY scientists have mastered the art and science of applying the piezo to cavities, bringing them to within several ten-thousandths a percent of the desired frequency.

Cavities in stereo

7 July 2011 Users can take a virtual tour through the European XFEL tunnel, currently under construction, walking through the newly planned facilities to get an idea of its space and future working conditions. The nine-cell structures of pure niobium are designed to speed up the electrons at DESY's FLASH, the European XFEL, and the ILC. The picture was taken in DESY’s IPP stereo projection room, where it is possible to project and view three-dimensional models on a 1:1 scale. Category: Image of the week | Tagged: ,
