Power napping for detectors

| 5 December 2013 If physicists had it their way, detectors of the future would be powered with air. They want no material and no electronic noise to disturb their measurements. Powering by air isn’t a realistic option, so electrical engineers are tackling the challenge, putting a lot of effort into keeping noise down and material out. One of them is Cristian Fuentes at CERN. His latest project: power pulsing for the CLIC detector. Category: Around the World | Tagged: , , ,

Running like an electron

| 7 November 2013 Hundreds of children (as well as some playful adults) turned into human electrons at the ILC exhibit for the German accelerator lab DESY’s Open Day on 2 November in a mini ILC. Category: Around the World | Tagged: , ,

Stairway study

| 10 October 2013 After publishing the physics and detector chapters for the CLIC Conceptual Design Report organised only through working groups on various different study topics and detector R&D projects, the CLIC physics and detector community has spent the last months putting a new organisation in place: the CLIC detector and physics study. So far, 19 institutes have joined the study that is hosted at CERN. Frank Simon, MPI Munich, was elected as the chair of the Institute Board and Lucie Linssen as the first spokesperson. At their meeting at CERN last week, some 50 representatives from the various institutes met at CERN to discuss progress on physics simulations and detector development.

Tunnel vision

| 13 June 2013 During the ECFA LC2013 workshop that took place a the end of May at DESY in Hamburg, the LC management, civil engineering and machine-detector interface experts visited the tunnel of the future European X-Ray Free-Electron Laser XFEL - a week before construction was officially finished. DESY and the European XFEL celebrated the completion of the construction work with a ceremony, atmospheric lights and music in the new tunnel. Watch the slideshow.

Setting the course for European particle physics

| 30 May 2013 On 30 May, at a special meeting hosted by the European Commission in Brussels, the CERN Council formally adopted the update of the European Strategy for Particle Physics. This strategy sets the course for the future of this research field in Europe, making recommendations for projects and research sectors to be pursued with priority, both the near-term and the long-term future.

Hiking like an electron

| 30 May 2013 Hiking for charity can be a bit like particle acceleration, say three DESY scientist who walked an Oxfam Trailwalk in Japan in May. Beta functions, final focus, samurais and a shrouded Mount Fuji were all part of their two-day adventure. Category: Around the World | Tagged: , ,

From Symmetry Magazine: The cherry pie collider

| 16 May 2013 What’s the next step in particle colliders? Symmetry takes a trip into the kitchen pantry to find out. Don't miss the video that (nearly) explains it all, using the analogy of protons vs cherry pies that was first brought by Hitoshi Murayama, deputy director of the Linear Collider Collaboration, during a recent press conference. Enjoy! Category: Feature | Tagged: ,

Good signal, little noise

| 18 April 2013 A concept to save space and power for future particle detectors called power pulsing has recently been tested and proven to work on one of the possible calorimeter options for the future ILC detectors. The silicon-tungsten electromagnetic calorimeter prototype took data in test beam and magnet at the German lab DESY. The project is currently run by groups from France and Japan.

Cherry seed colliders unite

| 7 March 2013 [caption id="attachment_26218" align="alignleft" width="300"] Image by Marcello Pavan, TRIUMF[/caption] According to Linear Collider Deputy Director Hitoshi Murayama, the Large Hadron Collider is a collider of cherry pies, with lots of cherries, pastry and cream flying off in all directions, while what scientists are really after is the collision of two cherry seeds. The ILC and CLIC, by contrast, are colliders of cherry seeds, he explained at a press conference at TRIUMF laboratory in Vancouver to mark the beginning of the Linear Collider Collaboration. "Throwing two cherry seeds at each other is difficult, but you can see clearly what's going on - and for the ILC that is similar to what happened in the early Universe," he said when asked about the fundamental differences between LHC and the linear collider. Detector Director Hitoshi Yamamoto added that once the LHC discovered the Higgs, "at the ILC we can do in a day” with the Higgs what it would take the LHC several years to accomplish. Linear Collider Board chair Sachio Komamiya estimated that some 80 to 90 percent of collisions at the ILC would feature the Higgs, making it easy to fund and study in detail. Barry Barish made the new value estimate for the ILC public at the conference. Watch the video of the press conference - in both English and Japanese - here.

Global Design Efficiency – the story of a group revolution

| 21 February 2013 It all started in 2004... or so. LC NewsLine recaps the important milestones in the Global Design Effort history, and present and former honourable witnesses remember and send wishes to Barry Barish and Sake Yamada. Category: Feature | Tagged: , , , ,
