LHC experiments back in business at record energy
LHC experiments back in business at record energy BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/lhc-experiments-back-business-record-energy) The Large Hadron Collider (LHC) started delivering physics data on 3rd of June for the first time in 27 months. After an almost two year shutdown and several months re-commissioning, the LHC is now providing collisions to all of

LS1 Upgrade of the ATLAS Level-1 Central Trigger Processor
LS1 Upgrade of the ATLAS Level-1 Central Trigger Processor Triggering at the LHC is a challenge: during Run-1 in ATLAS, the task was to select out of the 40 million bunch crossings per second the 1000 events most promising for data analysis. The first of three levels of this selection is the Level-1 trigger system,

LHC sees first circulating beams
LHC sees first circulating beams Long Shutdown 1 officially came to an end on 5 April 2015, when a beam of protons circulated the LHC for the first time after two years. Following this long period of upgrades, repairs, and consolidation, the LHC is now ready to restart at 13 TeV, almost double its previous

Focus on the Run Coordinators of the LHC Experiments (Part 2)
Focus on the Run Coordinators of the LHC Experiments (Part 2) Following two years of maintenance and consolidation work, the Long Shutdown 1 officially ended on 5 April 2015, when the first proton beams circulated the LHC. Now the LHC experiments are getting ready to operate once more and record the first collision data. In

Focus on the Run Coordinators of the LHC Experiments
Focus on the Run Coordinators of the LHC Experiments As the preparations for Run2 are coming to an end, and the first collisions are scheduled to take place in a few weeks, the control rooms of the LHC experiments have become hives of activity, getting ready to record the first data. Run Coordinators are responsible

LHC restart update
LHC restart update LHC run 2 is coming ever closer. Seven of the machine’s eight sectors have successfully been commissioned to the 2015 operating energy of 6.5 TeV per beam, and the eighth is not far behind. There will, however, be no circulating beam in the LHC this week. An intermittent short circuit to ground

ATLAS: Preparing for LHC Run2
ATLAS: Preparing for LHC Run2 The ATLAS teams are wrapping things up and prepare for Run 2, as Long Shutdown 1 is coming to an end. The collaboration has made major upgrades to increase the efficiency, safety, and environmental impact of the detector; 2014 was a really busy year. The ATLAS detector is now a

ATLAS micromegas detectors tested in T9
ATLAS micromegas detectors tested in T9 BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/atlas-micromegas-detectors-tested-t9) The upgrade of the ATLAS detector calls for a new generation of muon detectors capable of operating in a flux of collision and background particles approximately ten times larger compared to today's conditions. The new technology of micromegas detectors is one

ATLAS and LHCb evacuation exercises
ATLAS and LHCb evacuation exercises The PH department, in partnership with the HSE, the fire brigade, and the Group Leaders In Matters Of Safety (GLIMOS), conducts annual exercises to ensure safety at CERN. This year, as part of the continuous effort to improve even more the safety standards of CERN, evacuation exercises took place for

RD53: Development of pixel readout integrated circuits for extreme rate and radiation.
RD53: Development of pixel readout integrated circuits for extreme rate and radiation. In June 2013 the LHCC has endorsed the establishment of a new R&D collaboration, RD53, to address the challenges of making readout integrated circuits for the phase 2 pixel detector upgrades of ATLAS and CMS, as well as long term developments of interest
