ALICE

ALICE and BASE experiments present new results related to CPT symmetry

In August the ALICE experiment published a precise measurement of the difference between ratios of the mass and electric charge of light nuclei and antinuclei produced during heavy-ion collisions at the LHC. The article published in the journal…

Data Quality Monitoring: An important step towards new physics

Data Quality Monitoring (DQM) is an important aspect of every high-energy physics experiment. In the era of LHC, when the detectors are extremely sophisticated devices, an online feedback on the quality of the data recorded is needed to avoid taking…

LHC experiment release data in CERN's Open Data Portal

On 20 November 2014, CERN launched the Open Data Portal, making data from real collision events at the LHC experiments available for the first time to the general public. This project is part of the Organisation's policy of openness, which is…

LHC experiments back in business at 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 its experiments at…

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…

Injection tests make a splash

  On Saturday 7 March, two of the LHC experiments saw proton beams for the first time after a two-year stop. Beam 2 (anticlockwise) made it through LHCb at 10.30 and Beam 1 (clockwise) passed through ALICE at 17.00. The two experiments were…

Radiation Monitors Tested on Orion Space mission

On Friday 5 December, NASA's new Orion spaceship, a capsule built to take humans further into space than ever before, made its first test flight. The flight marked the first time, since Apollo 17 was launched to the moon in 1972, that a spacecraft…

ALICE looking into the future

Following a busy year, ALICE is now almost ready for the next run, as the teams make finishing touches before turning their focus towards re-commissioning and calibration. Thanks to the upgrades of the past year, Run2 will provide another in–depth…

The ALICE TPC Upgrade Plans

The expected lead-lead collision rate in the LHC Run3 (2019 onwards) is 50 kHz. This corresponds, on average, to a collision every 20 μs. In the ALICE TPC, a 90 m3 gas volume where ionization electrons take 100 μs to drift the full 2.5 m distance to…
