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.

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.

The year of the snake

| 10 January 2013 2013 is the year of the snake - according to Chinese wisdom, it will be a year of steady progress and attention to detail. This prognosis is something the ILC design team can certainly sign off on: attention to detail is intrinsic to the ILC'S precise collisions, state-of-the-art detectors and challenging machine. And steady progress is certainly ahead with the publication of the Technical Design Report in summer. The uroboros - the snake that eats its own tail - is also often the representation of the universe, where the very big mirrors the very small.

Bye bye DORIS

| 20 December 2012 The German lab DESY is saying good-bye to one of its accelerator workhorses, the DORIS ring. On 2 January 2013 the final beam will go round its tunnel. It has already stopped being a light source: the last positron beam reached the HASYLAB experimental huts on 22 October. Between then and now, DORIS reverted to its original raison d’etre: an accelerator for particle physics. Category: Image of the week | Tagged: ,

Media advisory: International Linear Collider to take next step

6 December 2012 The Global Design Effort and ILC Research Directorate, the international planning team for the International Linear Collider (ILC), will hand over the draft of the ILC Technical Design Report (TDR) to its internal oversight board ILC Steering Committee (ILCSC) in an official ceremony to be held in Akihabara, Tokyo, Japan on 15 December 2012 at 14:00 h JST. This marks the first step towards the completion of the final design for the ILC project.

Geometries of a future Higgs factory

21 November 2012 Last week at Fermilab, a select group of experts discussed whether an accelerator to purely exploit the science around the Higgs(-like) particle found at the LHC should be linear, circular or something completely different. The participants compared the options of a linear 250-GeV electron-positron collider and a circular 125 GeV electron-positron collider from the accelerator point of view as well as physics requirements for a Higgs Factory and other options for a Higgs Factory, including a muon collider and a gamma-gamma collider. More about the workshop and an article in symmetry magazine.

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: , , , , ,

Which way to the ILC, please?

18 October 2012 Drivers stuck in a traffic jam in Ichinoseki city are more likely to wonder about the mysteries of the Universe than about the latest Hollywood movie - at least if they take in the billboards at the side of the road. Japan's Iwate prefecture in the Tohoku region in the north of the country boasts a road sign underlining the region's interest in hosting the ILC. Category: Image of the week | Tagged: , , ,

Getting it all straight

| 4 October 2012 Linear collider detector experts get it straight - a vision of the XFEL tunnel that is. CLIC detector engineers from CERN visited DESY last week to discuss detector challenges such as earthquake stability, alignment, assembly planning and the construction of the detector's magnet yoke with their colleagues from the ILC's ILD detector. They also visited the tunnel for the European XFEL that is currently being constructed. Category: Image of the week | Tagged: , , , ,

Chancellor Merkel’s first cavity

| 27 September 2012 Chancellor Angela Merkel visited DESY on 19 September for a hall baptism: the experimental hall of DESY's light source PETRA III is now officially named Max von Laue, after the discoverer of diffraction of X-rays. DESY DG Helmut Dosch presents the German chancellor (who was a physicist before she became a politician) with a miniature accelerator cavity. In her speech, Merkel stressed the importance of fundamental research, freedom of science and the importance to communicate results. Check DESY's press release for more links, the chancellor's full speech (in German) and images. Category: Image of the week | Tagged: , ,
