ALICE (A Large Ion Collider Experiment) is a heavy-ion detector on the Large Hadron Collider (LHC) ring. It is designed to study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms.
In this article, I will show you how to proceed a man in the middle attack. In a network this attack allows you to re-route the traffic to your computer in order to analyse all the communication. In this example I will use a Linux computer (Lubuntu 16.04 x64) on a wireless network.
The LHC smashes groups of protons together at close to the speed of light: 40 million times per second and with seven times the energy of the most powerful accelerators built up to now. Many of these will just be glancing blows but some will be head on collisions and very energetic. When this happens some of the energy of the collision is turned into mass and previously unobserved, short-lived particles – which could give clues about how Nature behaves at a fundamental level – fly out and into the detector.
The largest volume detector ever constructed for a particle collider, ATLAS has the dimensions of a cylinder, 46m long, 25m in diameter, and sits in a cavern 100m below ground. The ATLAS detector weighs 7,000 tonnes, similar to the weight of the Eiffel Tower.
The detector itself is a many-layered instrument designed to detect some of the tiniest yet most energetic particles ever created on earth. It consists of six different detecting subsystems wrapped concentrically in layers around the collision point to record the trajectory
The trip start from the Chamonix city, where there is the cable cabin. I recommend you to arrive early (around the opening hours), because if the weather is good (that was my case), you will have a huge queue
First step you have to buy a ticket (45 minutes), then go to the queue to take the cable-cabin (45 minutes).
The climbing is about 30 minutes. It is composed of two steps:
- First one will climb you to a kind of plane where there is a café.
- Second one will climb you to the top of the "Aiguille du midi"
On the top you have lot of different activity:
- Panoramic view (takes lot of time to see all the point of view)
- Step onto the void, inside a glass cage out over a 1000 m precipice
- Exposition about altitude and the effect on the body (you can mesure the O2 saturation of you blood)
A very nice place if the weather is on your side
