Atlas Experiment: CERN Video, link: All LHC Experiment docs

In summary, the Transition Radiation, Semi-conductor and Pixel Detectors, innermost Atlas detectors are all housed inside a large, circular, underground facility. These detectors are used to detect particles as they travel along the proton beam.

First, the assembly, time lapsed of course...

This is a blow up of the Transition Radiation, Semi-conductor and Pixel Detectors, innermost Atlas detectors.

Description of layers of detectors and what each one is capable of detecting, from the inside (core) projecting outward:

Summary:

1. Pixel Detectors, thin strips of silicon
2. Transition radiation and semi-conductor tracker, capable of measuring trajectories of charged particles with accuracy 1/100 of mm. Consists of several hundred thousand tubes filled with gas and gold wire.
3. Calorimeters arranged as barrels: placed in the center and at the ends of the detector, two types, tile calorimeter: steel and particle illuminating material, second type: electromagnetic calorimeter made of lead bathed in liquid argon.
4. Outside of calorimeters, Muon detectors, the size of several football fields.
5. Further detectors placed at ends to measure particles at small angles to the proton beams.
6. Toroidal magnets placed at the ends to create intense magnetic fields needed.
7. More detectors at the ends to detect particles that make it to the edge of the nested detectors.

The second and third video's describe the types of particles and where in the layered tracker arrays each is detected. Good descriptions and location on each detector plate, strip, etc... with the type of particle that is detected, in blow up form.

Finally, a http://iopscience.iop.org/1748-0221/3/08" for all experiments at the LHC, including ATLAS.

Above link provided by a kind soul (many thanks) associated with the LHC Effort at CERN.

http://iopscience.iop.org/1748-0221/3/08/S08003/pdf/1748-0221_3_08_S08003.pdf" 438 pages, with better pictures and complete technical descriptions of Atlas, needless to say if this doesn't blow you away, then nothing will in this world. This link will be used for something I need to research a great deal more before posting.

Thanks for this. I am writing a term paper on CERN's accelerator complex and it's many experiments and this will come in quite helpful!

tatiana,

Good luck, a wealth of information here, you should be able to gather a broad view from the material easily.

For your benefit and everyone else I have modified my original post, and added another useful link at the bottom with description(s) and picture of LHC hardware list that can be accessed.

1. What is the Atlas Experiment and what does it involve?

The Atlas Experiment is a particle physics experiment conducted at the European Organization for Nuclear Research (CERN). It involves the use of the Large Hadron Collider (LHC) to accelerate and collide particles at high energies, allowing scientists to study the fundamental building blocks of matter and the forces that govern them.

2. Why is the Atlas Experiment important?

The Atlas Experiment is important because it helps us to better understand the fundamental laws of nature and the origins of our universe. By studying the particles and interactions produced in the collisions, we can gain insights into the nature of matter, dark matter, and the early universe.

3. What are the goals of the Atlas Experiment?

The goals of the Atlas Experiment include finding evidence for new particles and forces, testing the validity of the Standard Model of particle physics, and searching for answers to some of the biggest mysteries in physics, such as the existence of dark matter and the imbalance between matter and antimatter in the universe.

4. How does the Atlas Experiment work?

The Atlas Experiment works by accelerating particles to near the speed of light using the LHC and then colliding them at specific points within the detector. The resulting collisions create a spray of particles that are measured and recorded by various detectors within the Atlas detector. Scientists then analyze the data to look for patterns and evidence of new particles or phenomena.

5. What has the Atlas Experiment discovered so far?

The Atlas Experiment has made many important discoveries, including the observation of the Higgs boson in 2012, which helps explain how particles acquire mass. It has also provided evidence for the existence of new particles, such as the top quark and the tau neutrino. Additionally, the Atlas Experiment has helped to rule out certain theories and provided valuable data for further exploration and understanding of the universe.
