Gotta catch them all – and fast

| 22 July 2016 Silicon detectors play a crucial role in particle detectors, both present experiment at the LHC and future experiments like the ILC. More than 80 calorimeter and silicon tracking experts attended a dedicated workshop on high-granularity silicon devices, held last month in Hamburg.

Tunnel visions for civil engineers

| 7 July 2016 A delegation from the Japan Society of Civil Engineers including its president took to Europe last month to have a look at civil engineering project for large science facilities. They visited CERN and DESY to look at past and current building projects, which they would use as a reference in case ILC is constructed in Japan. Category: Around the World | Tagged: , , , ,

German particle physics community gives “strongest support” to ILC

| 26 May 2016 It may feel like only yesterday that the update of the European Strategy for Particle Physics was adopted, but preparations for a new one, planned for 2018/19, are already underway. Germany has now published its first conclusions from a workshop on future electron-positron colliders that are very supportive of the ILC. Category: Image of the week | Tagged: , , , , , ,

More time for collaboration

| 24 March 2016 DESY and KEK are two labs that have a lot in common. They know a lot about accelerators, operated and have operated a number of them in their long and eventful histories. They are their countries’ hubs for particle physics research, but they also run accelerators for photon science. They are national labs that collaborate closely with other institutes and labs from around the world. And, notably, with each other. At the recent DESY KEK Workshop at DESY in Hamburg, Germany, the two therefore decided to extend the existing cooperation agreement by another five years.

Unplugged: new magnet concept could lower CLIC’s power bill

| 3 March 2016 Spirits lifted by a motivating talk by CERN's new Director-General, scientists attending the recent CLIC workshop say that there’s a lot that’s happening in the world of the Compact Linear Collider study. Category: Feature | Tagged: , , , ,

ARUP tool shortlisted for prestigious prize

| 11 February 2016 Remember the ingenious civil engineering tool that British consultancy ARUP has developed for CERN's FCC and that is also being used for site-specific planning of the ILC? That thing where you can play around with shafts, tunnels and rock formations without leaving your desk? It's been shortlisted for a prestigious award, so keep your fingers crossed.

Here’s your physics case, once and for all

| 11 February 2016 Dear colleagues, this one is for you. All those paper writing thesis completing report submitting physicists out there: here comes a new central paper for your list of references and your reading list. It provides a comprehensive physics case for the e+e- linear collider and puts all the topics and ideas from theory, collider searches, astronomy in context to each other. It’s been published in the open-access peer-reviewed European Physical Journal C (EPJC). Category: Feature | Tagged: , , , , , , ,

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: , , ,
