28 January 2016Sometimes even linear-collider experts make semi circles, especially when you have to squeeze more than 200 participants into one picture (and it's raining). The CLIC workshop was held at CERN from 18 to 22 January. Get the latest on the Compact Linear Collider Study in a future issue of LC NewsLine.

Barbara Warmbein | 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.

Barbara Warmbein | 15 October 2015Probably the most advanced ultra-thin pixel sensors ever: DEPFET. Developed for the ILD detector’s vertex subdetector, they will be used in the Belle II detector – an extreme example of fast-forward technology spin-off. The first full-size module for use in Belle II has just been completed. It comprises a thin sensitive area (75 microns) with roughly 200,000 DEPFET pixels and the monolithically integrated silicon support frame with all necessary read-out electronics. Stay tuned for a more detailed report in a future issue of NewsLine.

Barbara Warmbein | 1 October 2015From cavity studies to shaping the future of particle physics in Europe: Eckhard Elsen, scientist at the German lab DESY, will become research director at CERN when Fabiola Gianotti becomes Director-General in 2016. Elsen is well known in the linear collider community for his central role advancing not only the the performance of high-gradient superconducting cavities but also of the linear collider project itself. He is a member of and has chaired numerous committees in the world of particle physics and beyond. His term of office covers the second run of the Large Hadron Collider LHC.
17 September 2015Working in particle physics can easily fill your day. But there's always more to life than physics – football, for example. Three core members of the linear collider management team turn out to also be hardcore fans of Sunderland Association Football Club – so much so that one of them, John Osborne, founded the Sunderland Swiss Branch. John Osborne is a civil engineer at CERN and heavily involved in the planning of tunnels for the linear collider (and other projects), while the other two are Directors in the Linear Collider Collaboration: Mike Harrison for the ILC and Brian Foster for Europe. They all come from the northeast of England, home of Sunderland football club. The Swiss branch has even made it into the Fanzine "Legion of Light"! Any more particle physics football fans out there?

3 September 2015In the last issue we celebrated the 10th anniversary of the ILC-constituing meeting in Snowmass. For those who missed it, here's the timeline of linear collider development since 2005. We're also still collecting your personal memories of highlights from the last ten years and hopes for the next ten!
20 August 2015The design is clunky, but the faces look familiar: the very first issue of NewsLine was published on 18 August 2005. It had lots of live coverage from the meeting in Snowmass that more or less officially started a global R&D project for the International Linear Collider. It made scientists from different collider and R&D backgrounds work together towards the goal of eventually building the next big adventure in particle physics. Some 400 issues of ILC / LC NewsLine later the accelerator and detector designs have matured a lot, the project has experienced some ups, some downs and has taken many "important steps towards realisation," including the selection of a possible site in northern Japan. While R&D continues and the community keenly anticipates results from the LHC's run 2, the project is now at a stage where its realisation is down to political decisions rather than technological challenges. Have a look at the first edition and the archive and send us your personal memories of highlights from the last ten years ans hopes for the next ten!

Barbara Warmbein | 6 August 2015Summer breaks don't exist for detector prototypes. For almost three weeks in July – around the time that a new temperature record of 39.7 degrees was measured in Geneva – the team working on the technological prototype of a potential hadronic calorimeter for the ILD detector at the ILC took data at the Super Proton Synchrotron test beam at CERN.
