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: , , , ,

Andy White and Marcel Stanitzki new SiD spokesmen

| 21 February 2013 There is a change at the helm of SiD, one of the two detector concepts for the ILC. After John Jaros and Harry Weerts have pushed SiD the LOI, the validation of SiD as one of two ILC detector concepts and collaboration in the CLIC CDR, the time is right for two new spokesmen to take over. These are Andy White and Marcel Stanitzki, whose role now is to strengthen the SiD detector concept and attract new collaborators from all the regions and and continue to develop and improve the SiD concept.

An eye on the pulse

| 6 December 2012 The technical prototype of the silicon-tungsten electromagnetic calorimeter, one of the calorimeter options for the ILC’s ILD detector, is about to spend its first weeks in a test beam at DESY. The team will test its performance under power-pulsed operation and take detector development one step further towards a real collider detector. Category: Around the World | Tagged: , , , , , , , ,

Cryo conveyor belt

| 21 November 2012 An industrial study commissioned by the Global Design Effort in collaboration with experts from CERN gives a clearer picture of how cryomodules for the ILC could be mass-produced by industry. The study, whose results were recently presented at a meeting between accelerator experts from different labs. A similar study has looked at cavity serial production. One of the scientists leading the cryomodule study, Vittorio Parma from CERN, was the driving force behind the cryostat assembly for 2000 cryomagnets for CERN’s Large Hadron Collider between 2003 and 2008 and thus predestined to lend his experience to the project.

Strip teaser

| 1 November 2012 A team of two scientists and four students from Shinshu University of Japan and Kyungpook National University of Korea have just packed up their cables, laptops and scintillator strips and left a test beam at DESY with many interesting results in their luggage. They tested the scintillator-strip-based electromagnetic calorimeter (ScECAL), one of the potential layers of a future ILC detector. Category: Image of the week | Tagged: , , , , ,

Grassroots master plan includes a Higgs factory

| 27 September 2012 Some 500 particle physicists from Europe and beyond met in Cracow, Poland, in September to kick-start the update of the European Strategy for Particle Physics, an initiative by the CERN Council that sets the European pace for global planning and cooperation on future projects in particle physics around the world. With the recent discovery of the Higgs-like particle at the LHC, a Higgs factory is high up on the wish list. Category: Feature | Tagged: , , ,
