What is the difference between CMS and ATLAS?

The ATLAS detector is about 25 m high, 45 m long and weighs about 7000 tons. The CMS detector is a bit smaller, but it is much heavier (about 12 000 tons). Overall, these detectors take the role of high-speed three-dimensional digital cameras.

What is the CMS collaboration?

The CMS Collaboration brings together members of the particle physics community from across the globe in a quest to advance humanity’s knowledge of the very basic laws of our Universe.

How many authors are in the ATLAS collaboration?

3000 scientific authors
ATLAS is run by a collaboration of physicists, engineers, technicians and support staff from around the world. It is one of the largest collaborative efforts ever attempted in science, with over 5000 members and almost 3000 scientific authors.

Who runs the Hadron collider?

the European Organization for Nuclear Research
Large Hadron Collider (LHC), world’s most powerful particle accelerator. The LHC was constructed by the European Organization for Nuclear Research (CERN) in the same 27-km (17-mile) tunnel that housed its Large Electron-Positron Collider (LEP).

What is CMS LHC?

The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). It has a broad physics programme ranging from studying the Standard Model (including the Higgs boson) to searching for extra dimensions and particles that could make up dark matter.

What is CMS tracker?

The CMS silicon tracker consists of two tracking devices utilizing semiconductor technology: the inner pixel and the outer strip detectors. They operate in a high-occupancy and high-radiation environment presented by particle collisions in the LHC.

What is CMS CERN?

How many countries have collaborated on the LHC project?

The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories, as well as more than 100 countries.

What is hoped to be Learnt from studies at the LHC?

That’s the what, but why? The goal is to understand the nature of the most basic building blocks of the universe and how they interact with each other. This is fundamental science at its most basic. View of the LHC in its tunnel at CERN (European particle physics laboratory) near Geneva, Switzerland.

Why is the LHC so important to Atlas?

With much greater energy and greater collision rates, the LHC produces a tremendous number of top quarks, allowing ATLAS to make much more precise measurements of its mass and interactions with other particles.

What are the coordinates of the ATLAS experiment?

ATLAS experiment. Coordinates: 46°14′8″N 6°3′19″E / 46.23556°N 6.05528°E / 46.23556; 6.05528 ATLAS (A Toroidal LHC ApparatuS) is one of the seven particle detector experiments constructed at the Large Hadron Collider (LHC), a particle accelerator at CERN (the European Organization for Nuclear Research) in Switzerland.

Why does LHCb perform so well this year?

This excellent performance is mainly due to the higher efficiency of the accelerator this year. LHCb has recorded 1.67 fb -1 of proton-proton collisions this year, 5 times more than in 2015, a year in which LHC collider was setting-up its operation at the record energy of 13 TeV.

Who is in charge of the Atlas project?

The project was led for the first 15 years by Peter Jenni, between 2009 and 2013 was headed by Fabiola Gianotti and from 2013 to 2017 by David Charlton. The ATLAS Collaboration is currently led by Karl Jakobs.
