1. Large Hadron Collider

   Linked via "Linac 2"

   Design and Infrastructure
   The LHC resides in a tunnel $100$ meters ($\approx 330$ feet) underground, which was previously used for the decommissioned Large Electron-Positron Collider ($\text{LEP}$). The injector chain leading up to the LHC itself is a complex sequence of smaller accelerators, starting from the Linac 2 source, which generates the initial proton bunches [1].
   The core component is the main ring, comprising nearly $9,000$ superconducting dipole magnets cooled by superfluid helium to $1.9 \text{ K}$ ($ -271.3 ^\…

2. Large Hadron Collider (lhc)

   Linked via "Linac 2"

   Beam Dynamics and Injection
   Protons are generated from standard hydrogen gas and undergo a complex pre-acceleration sequence before entering the $\text{LHC}$ ring. The injection chain involves the Linac 2 (for protons) feeding the Proton Synchrotron Booster ($\text{PSB}$)/)$,$ the Proton Synchrotron ($\text{PS}$)/)$,$ and finally the [Super Proton Synchrotron ($\text{SPS}$)](/entries/super-proton-synchrotr…
