EldwinSchrodinger @ LHC - Brief Introduction

loving you always ♥

Well have you all heard of particle accelerators? I bet most of you do and the next thing is, where are they located?
There are a few operating ones today which ranges from linear accelerators to circular ones which spans several kilometers
A well known linear accelerator would be SLAC (Stanford Linear Accelerator Center) and the latest upcoming largest
Proton-antiproton collider would be the LHC (Large Hadron Collider). Spanning a huge aerial distance of 27km located at Geneva.
In theory, its said that this machine is capable of producing the elusive Higgs Boson which is the last particle in the list of the standard model.

There are 6 main detectors built along the accelerator. ATLAS(A Toroidal LHC ApparatuS),ALICE (A Large Ion Collider Experiment),
CMS (Compact Muon Solenoid) , LHCb and f which stands for 'beauty' and forward respectively.

So how it works or what actually happens. Here's a rough guide.

1) Imagine a torch shooting hydrogen atoms in a orderly manner and these particles are injected into LINAC2 where the electrons are stripped off the hydrogen atoms, leaving the protons particles behind. (Stage 1)

2) These protons are then accelerated at 1/3 the speed of light and exits the LINAC2 accelerator and goes into the boosters where its approx 170 meters in circumference. (Stage 2)

3) The booster then accelerates the protons to 91.6% the speed of light and being packed together before leaving the booster for the proton synchrotron which is of about 600+ meters in circumference. (Stage 3)

4) After circulating for 1.2 seconds around the Proton Synchrotron and reaching 99.9% the speed of light. Its here, that the point of transition is reached, Hence the energy from the pulse cannot increase the speed of the particles as it has already reached its max speed.

5) Instead, increasing the mass of the proton. the energy of the particles is measured in ElectronVolts(eV) and in this point, the particles have reached 25GeV and is 25 times heavier than what it was at rest.

6) The protons are now channeled to the Super Proton Synchrotron which is 7km in circumference. Its main purpose is to increase its energy to 450GeV. (Stage 4)

7) Its ready to enter the Large Hadron Collider which mentioned earlier, is 27km in circumference.

8) The particles are now travelling so near the speed of light, it goes around the lhc 11000 times per second.

9) Its now that each proton has energies of 7TeV! Thats 7000 times heavier than a proton particle at rest.

10) When 2 protons at this stage collides, it will produce energies of 14TeV and simulates the event of the big bang and the particle tracks of the collision course is analyzed by super computers around the lab.

Where we hope that these tracks give us and answer to how our universe has evolved and what would happen in the future.
