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: ,

All aboard the long bunch train

| 30 June 2011 Learning to stabilise a particle beam of longer pulses such as those needed for the ILC requires diligence, patience and practice. ILC and FLASH scientists share the fruits of all three at the recent workshop on long bunch trains. Category: Feature | Tagged: , , , ,

A new beginning – and no strings attached

| 23 June 2011 Winner of a Humboldt Professorship, Brian Foster has just taken up his work at DESY and University of Hamburg as a joint professor for experimental physics, focusing on accelerators for very high energies. He intends to spend the 5 million Euros for five years to the greatest effect, and the ILC will play a very strong part in his plans. Category: Director's Corner | Tagged: , , , , , , ,

Present, future and science fiction of particle physics

| 2 June 2011 Brian Foster, recently awarded the Humboldt professorship by the Alexander von Humboldt Foundation, has begun work in Germany this week. He hopes to advance particle physics by exploring new methods of acceleration, analysing unique physics data and of course playing his violin. Category: Feature | Tagged: , , ,

A robot to watch out for defects

| 14 April 2011 A 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. Category: Around the World | Tagged: , , , , ,
