From metal sheet to particle accelerator (part 3 of 3)

| 12 May 2016 If you're an electron, a ride in a cavity is pretty much the coolest thing that can happen to you. If you're an accelerator and you need huge numbers of cavities you better make sure they're all of outstanding quality – which is what the X-ray free-electron laser European XFEL under construction in Hamburg has just finished. In a series first published in DESY inForm, we look at how a niobium sheet turns into a curvy beauty. Part three describes how they make their way from test benches into the cryomodules and, finally, into the tunnel. Category: Around the World | Tagged: , , , , , , ,

French linear collider days review Linear Collider status

| 14 April 2016 For their 4th edition, the French Linear Collider Days brought participants to Paris to review recent national development on accelerator, physics and detectors as well as to hear about the global progress of the project at the international level. The meeting was jointly organised by members of CEA/Irfu and IN2P3. Roman Pöschl, member of the organisation committee, summarises. Category: Around the World | Tagged: , , , , ,

Family reunion of many generations of TESLA technology

| 14 January 2016 Quality factors, nitrogen doping and "the golden age" of superconducting radio frequency technology: an in-depth report from the recent TESLA technology collaboration meeting, also covered in this week's Director's Corner. Category: Feature | Tagged: , , , , , ,

Higgs found at DESY

| 12 November 2015 [gallery ids="35324,35319,35320,35322,35321,35323,35317"] The German research centre DESY opened its doors to the public on 7 November, a day now known as DESY DAY. More than 18000 visitors came to see real accelerators, braving long queues and Hamburg drizzle to walk through parts of the European XFEL, PETRA or HERA accelerators, to visit DESY's workshops and partner labs on campus, learn about vacuum, magnetism, cryo technology, molecular biology, crystal and much more. Some of them even discovered the Higgs, which was roaming around on campus, happy to be photographed. At the stand of DESY's linear collider groups, visitor could try a magnetic linear accelerator, cable a detector prototype and even play electron in an accelerator tunnel. In a mocked up linac tunnel stretching a couple of metres and ending in a crash mat, children accelerated like electrons in a cavity and even had their average speed measured. "We recorded every of the approximately 3000 runs," explained Marc Wenskat of DESY's linear collider accelerator group, one of more than 1200 volunteers who tirelessly explained to visitors what they do all day, and why. "Considering that most kids had more than one go, we estimate that some 1500 kids visited our stand – probably about equal to the number of children on site!" For the next open day - planned again to coincide with Hamburg's Night of Science in two years - the team is considering to turn the crash mat into a calorimeter to measure the runner's impact and make it even more of a linear collider experience.

Addressing the known unknowns

| 6 August 2015 I am sure that my readers will remember that in my last Director’s Corner, in April, I threatened to write at some future date about the new Project Implementation Planning (PIP) document. Those of you with an even longer memory, going back to my Director’s Corner of April 2014, may even remember what it is. Just in case, however, I take this opportunity not only to honour my promise of last April to also to refresh your memory and to offer you an opportunity to peruse the final document.

“Let’s get it straight”

| 9 July 2015 The visual petition continues: scientists from DESY and the University of Hamburg recently gathered in the tunnel of the European XFEL to shoot this group #mylinearcollider video and a few others. Category: Image of the week | Tagged: , ,

The European XFEL – helping pave the way for the ILC

| 11 June 2015 The European XFEL at DESY, Germany, will be a brilliant light source for a broad range of fundamental research in all areas of science – but it is also the first great mass production of the so-called TESLA technology. The ILC community is thus watching the construction of the European XFEL very closely. Category: Around the World | Tagged: , , , , , , , ,

A year with the ILC

| 8 January 2015 For the ILC, 2014 was a year of progress in many areas, but the most important activities were centred in Japan, where Japan’s Ministry of Education, Culture, Sports, Science and Technology has started deliberations to evaluate the physics justification as well as the scope and cost of the project. The past year also featured nice results from the ATF2 facility in Japan and the XFEL in Europe. Mike Harrison, associate director for the International Linear Collider in the Linear Collider Collaboration, didn’t avoid the temptation to look back before looking ahead to 2015.
