Answer:
It is designed to accurately detect and study Muons.
Step-by-step explanation:
Compact Muon Solenoid (CMS) is part of Large Hadron Collider (LHC) of CERN and has a use as a general purpose detector. It weighs around 14000 Tonne and built around a giant solenoid magnet. That's how it got its name: Compact Muon Solenoid (CMS). It generates 4 Tesla magnetic field that is around 100000 times the Earth's magnetic field. A yoke made up of steel is used to confine this intense field. This strong magnetic field is used to bend the path of particles.
In LHC, protons are accelerated to a very high speed in clockwise and anticlockwise direction and then collided with each other. On collision particles will be sprayed out in all directions. CMS takes the photograph and collects data during these collisions. Its main purpose is to detect Muons which are around 200 times heavier than electrons.
