ILC starts at 500 GeV and goes down in energy

| 25 June 2015 The default collision of the energy of the ILC has always been 500 GeV with promises of an upgrade to 1000 GeV. A while ago, alternative scenarios of a staged ILC that would start at 250 GeV and ramp to 500 GeV later were discussed. All scenarios were evaluated in the community and Hitoshi Murayama reports on the result: the ILC would start at 500 GeV, then go down to lower energies before possibly receiving an upgrade to even higher ones.

LHC is back in business

11 June 2015 On 3 June, the Large Hadron Collider (LHC) at CERN started delivering physics data for the first time in 27 months at the record energy of 13 TeV. This marks the start of season 2 at the LHC, opening the way to new discoveries. The LHC will now run round the clock for the next three years."Run 2 of the LHC can well decide the future of the field. I’m super excited!" said LCC deputy director and theorist Hitoshi Murayama on the day. Category: Image of the week | Tagged: , , , ,

Crossing technical and cultural borders

| 28 May 2015 Accelerator experts from Europe and Japan have a long history of cooperation for projects such as ATF at the Japanese lab KEK, and of course the Large Hadron Collider at CERN. A new EU-funded project makes sure that cooperation continues with future projects like the high-luminosity LHC, the Future Circular Collider FCC, CLIC, the ILC and many more. The first researcher (from the German lab DESY) has already spent nine weeks in Japan to improve simulations for site-specific machine-detector-interface questions for the ILC.

LHC commissioning continues in spite of obstacles

| 14 May 2015 After almost two years of major work on the machine and its detectors, the Large Hadron Collider is in the middle of the so-called commissioning phase. During the roughly two months of commissioning, the operators check out every little system in the large complex that is the LHC. LCC Director and former LHC project leader Lyn Evans watches and learns from the sidelines. Category: Director's Corner | Tagged: , , , ,

LHC breaks new energy record

| 16 April 2015 6.5 TeV in a circulating beam! Since the LHC's restart on 5 April after its log shutdown, operations have gone smoothly in the world's most powerful particle accelerator. Since 10 April, the machine is holder of a new energy record (breaking the record it set itself), accelerating proton beams up to 6.5 TeV. According to CERN, the operators are now taking a 'softly, softly' approach, increasing little by little the number of bunches in the beams.They expect first low-energy collision in the coming weeks and the greatly-expected 13-TeV collisions sometime in June.

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: , , , , , , , , ,

Updating the physics case for the ILC

| 19 March 2015 The physics case of the ILC boils down to three main points, says Hitoshi Yamamoto, Director for Physics and Detectors in the Linear Collider Collaboration. A physics case is a scientific justification based on studies and theory. And while the case for the linear collider has been made many times, the LC physics community thinks that it is now much clearer. Category: Director's Corner | 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: , , , , , ,

LHC’s two-year shutdown drawing to a close

19 February 2015 Two years after the team in the CERN Control Centre switched off the beams in the Large Hadron Collider (LHC) on 14 February 2013 the LHC is set to start up again at the end of March. Hundreds of engineers and technicians have been repairing and strengthening the laboratory's accelerators and experiments in preparation for running the LHC at the higher energy. So what has the work achieved? 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: , , ,
