Progress on Toroid Magnets
– The magnets on either end of the ATLAS detector (called end–cap toroid magnets) dominated November’s work in the experimental cavern. The ATLAS magnet team took a significant step towards finishing work on the ATLAS detector as testing of the magnets began.Read more →
The pixels find their way to the heart of ATLAS
– Leading up to the lowering of the pixel detector into the ATLAS cavern, final preparations were proceeding quickly.Read more →
ESA/NASA astronaut Christer Fuglesang visits the ATLAS cavern
– On 14 June, 2007, ESA/NASA astronaut Christer Fuglesang visited the ATLAS cavern. A former CERN fellow working on ATLAS, Christer went on to become the first Swedish astronaut and participated in the STS-116 Space Shuttle mission to the International Space Station last December.Read more →
The complex and spectacular lowering into the cavern of the huge end-cap toroid magnet on side A
– On 13 June 2007 the first of two giant toroid magnet end-caps was lowered into the ATLAS cavern on the A side. This complex and spectacular operation was completely successful.Read more →
Triggering and measuring bent cosmic muon tracks with the muon spectrometer barrel for the first time
– Data have recently been collected with the toroidal magnetic field will provide for the first time the measurement of the cosmic ray muons' momenta in the ATLAS experiment and allow studies on trigger optimization, chamber calibration, chamber alignment and magnetic field maps. More than one million events were acquired. They are now being analyzed by enthusiastic members of the collaboration.Read more →
Development of the ATLAS control room
– The ATLAS control room will become the brain of the detector operations. At the moment six of the final fifteen stations are already in place.Read more →
The ATLAS Detector safety system
– The ATLAS Detector safety system (DSS) has the mandate to put the detector in a safe state in case an abnormal situation arises which could be potentially dangerous for the detector. It covers the CERN alarm severity levels 1 and 2, which address serious risks for the equipment.Read more →
First combined SCT/TRT end-cap cosmic rays seen in building SR1
– Following the successful combined SCT/TRT barrel test in the Spring 2006, a similar combined SCT/TRT endcap test is currently being performed in the SR1 building on the ATLAS experimental site at CERN. One quadrant of the SCT and two sectors of the TRT have been cabled up and are used in this test. The data taking and combined testing is expected to last until December 11th.Read more →
The pixels system: last but not late!
– After almost 15 years of R&D and prototyping, the ATLAS pixel detector is finally almost ready for installation in ATLAS, and its first rendez-vous with colliding beams!Read more →
Barrel toroid magnet fully charged to nominal field, and it works!
– After a few weeks of testing up to intermediate currents, finally, on Thursday evening November 9, the current in the Barrel Toroid was pushed up to its nominal value of 20500 A and even 500 A beyond this value to prove that we have some margin. It went surprisingly well.Read more →
