Editor's Notes
- Paper title: “Paricle Accelerators: a brief paper on high-energy particle physics revolving around the Large Hadron Collider.”
- Introduction
- The general structure of accelerators. Injector LINAC Booster PS Intersecting storage rings for collision

- The LHC
- Issues
- Higgs Boson existence
- LHC will recreate the big bang for this sake.
- A look at the working of LHC
- Hydrogen atoms fed into source chamber of LINAC
- Occurs in the injector
- Electrons stripped off to leave Hydrogen nuclei. Protons accelerated by an electric field into LINAC (1 of LHC)
- Occurs in LINAC
- Travel like a rocket taking off Attain 1/3rd the speed of light Enter the booster
- Enter the booster
- Speed boosted by a varying electric field and perpendicular magnetic field in accordance with elementary physics
- Leaves to the PS
- Follow 2 proton packets: 99.9% of light velocity reached Energy increase translated to increase in mass Energy of each proton=25GeV Sent to stage 4: SPS
- PS
- Increased to 450GeV Made suitable to enter Orbit of LHC: Intersecting rings for collisions and experiments.
- Orbit/ISR
- Near Alps, between FRA and SWZ 27km circumference 2 vacuum pipes with proton beams travelling in opposite directions: anti-clockwise and clockwise Crossover occurs in four detector caverns where collisions can be made for experiments Protons injected for half and hour, 2808 packets ready for collision Speed is very near to that of light: goes around the 27km ring 11,000 times per second Final energy during collision: a combined 14 TeV, protons are 7000 times heavier than rest mass Collision debris is tracked using detectors. 12000Amps used to keep protons inside the rings: achieved by making LHC colder than outer space so its magnets become superconductors Particle tracks will give insight into the birth of our universe
- Particle track picture obtained
- Results
- Pions and kaons not found
- Higgs Boson: outer, unnecessary tracks need to be eliminated first
- Quotes
- Prof David Evans: a new outlook at the pseudorapidity of the LHC experiment
- What next?
