Getting it all straight

Image: DESY | 4 October 2012 Linear collider detector experts get it straight - a vision of the XFEL tunnel that is. CLIC detector engineers from CERN visited DESY last week to discuss detector challenges such as earthquake stability, alignment, assembly planning and the construction of the detector's magnet yoke with their colleagues from the ILC's ILD detector. They also visited the tunnel for the European XFEL that is currently being constructed. Category: Image of the week | Tagged: , , , ,

Proposing a fishcake shape

| 27 October 2011 Kamaboko is a type of Japanese fishcake with a distinctive loaf shape, usually served sliced thin with dipping sauce such as soy sauce and wasabi or as a topping for noodles. It is also the shape of the newly proposed ILC tunnel design for an Asian mountain site. 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.

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: , ,

Getting a vision of tunnels

| 16 December 2010 Early November, four members of the Global Design Effort Conventional Facilities and Siting group and two guests from Japanese industry visited DESY in Hamburg, Germany, for two days. They wanted to find out more about the current state of the European X-ray Free Electron Laser (XFEL) civil construction and to get information about other relevant projects like DESY Category: Around the World | Tagged: , , ,

Linear collider scientists tour the Mont Blanc tunnel

| 2 December 2010 To see one example of tunnel safety done right, scientists and engineers in the linear collider community took a tour of the Mont Blanc tunnel earlier this autumn. The road tunnel, an 11.6-kilometre thoroughfare that connects France and Italy, is a model of safety in civil engineering. Category: Feature | Tagged: , ,

A tunnel for (module) dummies

30 October 2008 It feels like the real accelerator tunnel, but it’s only building 71 at DESY in Hamburg. It’s basically a tube made of concrete, 51 metres long and 5.20 metres in diameter. One accelerator module hangs from the top of the tube, water pipes, cable trays and ventilation ducts are installed and other accelerator parts stand around on the tunnel floor. All these are dummies, some even made of wood, but they are life-size dummies in building 71: the European XFEL mock-up tunnel. Category: Feature | Tagged: , ,

One Tunnel or Two

| 1 December 2005 Should we build the ILC using one underground tunnel? Or should we build it using two adjacent tunnels, one containing the support instrumentation and the other containing the accelerator? Category: Director's Corner | Tagged: , ,

Cape Town
