Mini Models of the CMS Detector at CERN

Created by Davide Primc for the CMS experiment at CERN. 

The CMS detector at CERN is one of two multi-purpose detectors on the LHC (Large Hadron Collider). CMS acts as a giant, high-speed camera, taking 3D “photographs” of particle collisions from all directions up to 40 million times each second. Although most of the particles produced in the collisions are “unstable”, they transform rapidly into stable particles that can be detected by CMS. By identifying (nearly) all the stable particles produced in each collision, measuring their momenta and energies, and then piecing together the information of all these particles like putting together the pieces of a puzzle, the detector can recreate an “image” of the collision for further analysis.

At 15m high and 21m long, the CMS detector is quite compact for the incredible work that it does. These prints show a tiny model of the detector with a cut out section so that some of the internal details are revealed, something along the lines of this diagram

The files contains two versions of the mini CMS detector:

1. Single colour version, containing:
   • central section
   • one cut out end section
   • one full end section
   • 2 feet for the end sections
2. Multicolour version, containing the same as single colour but with different sections delineated in different colours. The default colours are as follows:
   • Slot 1: grey/silver
   • Slot 2: red
   • Slot 3: yellow
   • Slot 4: blue

The ‘feet’ slot into the end sections so they can stand on their own, while the central part has a stable stand built into the design. 

When assembled, the model is about 6.5cm in length, about 4.5cm in height. The model can be scaled to print bigger too. 

You can also check out a much bigger and more complex version of the detector here: https://www.printables.com/model/904-cerns-cms-detector 

We find that they come out very pretty also using rainbow filaments!
