11 August 2011The 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.

21 July 2011The 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!

7 July 2011Users 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.

Barbara Warmbein | 14 April 2011A small group of young researchers at DESY, Germany, is working on a robot that could drastically reduce the time it takes to optically inspect a cavity. Their work covers everything from the pure mechanics of the workbench and fine-tuned motors for moving the heavy parts to developing sophisticated methods of automatically analysing the pictures. Cavities might eventually pass the check in two hours instead of the one-and-a-half days it takes today.
