The ultimate collider gift list

| 10 December 2015 Do you know a linear collider enthusiast and would you like to surprise him or her with a gift? Or are you a linear collider enthusiast and as such too busy to go gift shopping? Then agonise no more. We’ve done some extensive research and proudly present a list of some of the best linear-collider-related gifts available online… 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.

Size-0 module

| 15 October 2015 Probably 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. Category: Image of the week | Tagged: , , ,

Eckhard Elsen to become research director at CERN

| 1 October 2015 From 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.

Back in the beam

| 17 September 2015 Calorimeter prototypes have been taking showers at CERN – particle showers, that is. Detector developers have just packed up their equipment after finishing a campaign to understand the time structure of hadron showers. And they are happy with what they achieved. Find out how a beer chiller played a role in the test beam as well… Category: Around the World | Tagged: , , , , , , , , ,

Here’s one we made earlier

| 17 September 2015 Particle detectors need to be at the forefront of technology in order to capture particle collisions in great detail and quick succession. R&D projects for upgrades of existing detectors or future ones are busy around the world, and sometimes the technologies developed and studied in these projects can help out in others. LC NewsLine has two examples. Category: Feature | Tagged: , , , , , , , , , , ,

Fresh funding for technical detector prototypes

| 3 September 2015 Detector R&D for future projects has just received a boost in Germany. Six universities are receiving some 1.8 million Euros from the German ministry of education and research (BMBF) for the next three years – twice the amount that was available before. The project will concentrate on improving the time projection chamber for the ILD detector, one of the two planned ILC detector concepts, and the hadronic calorimeter based on SiPMs. Category: Around the World | Tagged: , , , , , , ,

Expert puts report into context

| 3 September 2015 The summary of discussions published by the ILC Advisory Group to Japan’s funding agency MEXT is subject of a lot of discussion within the community. Why was it published now, what does it mean? NewsLine spoke to Satoru Yamashita from the University of Tokyo to find out more. Read also this week’s Director’s Corner.

And Still They Will Collide

| 20 August 2015 Is the beam delivery system delivering? Ten years ago, at the Global Design Effort’s formative meeting in Snowmass, Colorado, ILC communicator Perrine Royole-Degieux interviewed Phil Burrows, then professor at Queen Mary University of London, about the beam delivery system. How has the home straight where the particle bunches get squeezed, focused and brought to collision, evolved in a decade? Category: Feature | Tagged: , , , ,

Calorimeters don’t take holidays

| 6 August 2015 Summer 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.
