Ready for the jump

| 19 March 2015 The Large Hadron Collider is about to start up again as an almost new machine and almost twice the previous collision energy. With first beams possibly circulating by the end of the month and first collisions expected for the beginning of summer, physicists around the world cannot wait to see what the collisions of Run 2 will reveal. Will there be first signs of supersymmetry, a possible key to the as yet locked dark universe? What will the properties of the Higgs boson reveal? Will there be unexpected peaks in the data? And how do these results translate to the ILC? LC NewsLine speaks to two theoretical physicists. Category: Feature | Tagged: , , , , , , , , ,

Linear collider technology checks LHC lumi

| 5 March 2015 There’s a piece of linear collider detector technology that is getting ready to take real collision data. The linear collider may be at planning stage, but right in the middle of the CMS detector, a luminometer based on work done for the forward region of the ILC’s ILD detector is very much a working piece of kit. It will measure the luminosity in CMS, ie the rate of collisions that the LHC produces per second, and the beam-induced background. Category: Feature | Tagged: , , , , , ,

Tech transfer from linear collider to LHC detector

| 19 February 2015 The CMS detector at CERN's Large Hadron Collider is very much a detector at work. It co-found the Higgs particle in 2012 and, although still in Lang-Shutdown-1 mode, it's ready for the second LHC run. In it: a piece of linear collider technology. Stay tuned for the whole story in a future issue of LC NewsLine. Category: Image of the week | Tagged: , , ,

CLICing into action

| 5 February 2015 The first prototype module of CLIC is operational in the CLIC test facility. The Compact Linear Collider Study shows that it does what it says in the acronym: a compact accelerator module, fed by high-power waveguides, cables and cooling tubes, sits elegantly on a custom-made mechanical structure that can be moved in all directions to ultra-high precision, and tests how all the little details work that turn a metal structure into a functioning accelerator module– frequency, losses, damping, acceleration, deceleration. At the CLIC test facility you see none of the heavy-duty steel pipes that characterise the dipole magnets of the LHC. Category: Around the World | Tagged: , ,

2020 on the horizon

| 22 January 2015 Good news for detector developers in Europe: the AIDA-2020 proposal to the European Commission has been selected to be funded as part of the Horizon 2020 programme. This means that future projects needing state-of-the-art particle detectors like the Large Hadron Collider upgrade and the linear collider will receive a total of ten million euros funding over the next four years. Thirty-eight participants from all across Europe take part in AIDA2020, including CERN as coordinating institute, making it the largest European detector R&D project.

A kimono for a laboratory

| 8 January 2015 The mayor of Ichinoseki city, Osamu Katsube, and the whole city sent a special gift to CERN for its for its 60th birthday, which it celebrated in 2014: a red chanchanko set. It consists of a red vest, hat and folding fan. "'Kanreki' is one of the ancient traditions of celebrating longevity. It is held to celebrate the long life and health of someone who has reached a certain age and to pray for their continued health. This age is 60 years," the mayor explains in the accompanying letter. "We wish CERN further progress with its motto 'Science for Peace'." Find out more about the tradition Category: Image of the week | Tagged: , ,

Back to the future

| 11 December 2014 The Future Circular Collider (FCC) study, though even further in the future than the ILC, might be feeding technology back to its linear cousin. An interactive tunnel-planning tool developed by a civil engineering design company for planning the future circular colliders in the CERN vicinity could prove to be useful for detailed planning and design optimisation of the ILC in the designated Kitakami site.

Summer students reunite at test beam

| 26 November 2014 Four consecutive generations of former DESY summer students had an unplanned reunion at CERN recently: they were all around for the test of of the prototype of the analogue hadronic calorimeter for the ILC's ILD detector. They had all worked on this project as summer students. Category: Image of the week | Tagged: , , , ,

Green ILC: towards sustainable colliders

| 30 October 2014 Smashing particles together at high energies is power-consuming business. People around the world are discussing to see if the ILC could be made green in the hope to finally reach complete sustainability. More efficient klystrons and cryocoolers, recovering and recycling heat wastes, embedding renewable energies and storage technologies are some of the main issues. The ILC could bring back high-energy physics to one of its core businesses: energy. Category: Around the World | Tagged: , , , ,

Calorimeters enjoy beam time

| 16 October 2014 Test beam season has started again. Two potential prototypes for future ILC detectors are being tested in a beamline at CERN that delivers hadrons from the proton synchrotron, CERN’s workhorse accelerator. The CALICE collaboration is looking forward to getting its hands on the fresh test beam data. Category: Around the World | Tagged: , , , , ,
