Identifying particles
Here you can review how the detector is built. You will learn how elementary particles can be identified and how you can recognize them with our program. In a concluding exercise you may test your newly acquired knowledge.


Time for active playing! Discover the signals left in the detector by elementary particles with the help of the following interactive animation of ATLAS. Choose the name of a specific particle in the upper menu and follow its way through the detector. Keep in mind that a dotted line represents the path of a neutral particle, which is not seen by the detector until it showers in a calorimeter, if at all.



The program that we will use and that is elucidated on the next page illustrates events of proton-proton collisions in cross-sectional similarly.



If you do not yet understand the structure of the ATLAS detector, you can find more information under the menu item ATLAS detector.
