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…

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,…

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…

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…

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…

ATLAS micromegas detectors tested in 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…

ATLAS LS1 considerations

Ten months passed from the beginning of this very hectic Long Shutdown 1 (LS1) and ATLAS went already through so many changes and operations, that it becomes hard to list all of them. LS1 reminds me of the construction time when many people were…

Building an outreach application for ATLAS

Greetings, my name is Nathaniel Chandra Harjanto, a summer student of CERN Summer Studentship Programme 2013 from Indonesia, a country in South East Asia. I am part of Indonesian student group consisted of 3 persons which become the first Indonesian…
