Why CERN Energy Level Seems Low?

Click For Summary
SUMMARY

The CERN facility can achieve particle energies up to 14 TeV, with protons reaching 6.5 TeV each, resulting in a total collision energy of 13 TeV. The total energy of all protons in the beams is approximately 600 MJ. The limitations on energy per proton arise from the magnetic field strength and curvature radius, necessitating new infrastructure and advanced magnet designs for further increases in energy levels.

PREREQUISITES
  • Understanding of particle physics and energy levels
  • Familiarity with CERN's Large Hadron Collider (LHC) specifications
  • Knowledge of magnetic field strength and its impact on particle acceleration
  • Basic concepts of accelerator physics and tunnel design
NEXT STEPS
  • Research advanced magnet designs for particle accelerators
  • Explore the engineering challenges of building new accelerator tunnels
  • Learn about the principles of magnetic confinement in particle physics
  • Investigate the energy scaling limits in high-energy physics experiments
USEFUL FOR

Particle physicists, accelerator engineers, and anyone interested in the limitations and advancements in high-energy particle acceleration technology.

I heard that Cern can give particles energy up to ##14TeV## which its like ##2.2430 × 10^{-6}##joules.But it seems so low energy...Why can't we give more energy ? What am I missing
Thanks

That is energy per particle. A macroscopic object has \sim 10^{23} particles.
 
Oh I see
 
The protons have up to 6.5 TeV (design: 7 TeV) each, a collision of two protons has a total energy of 13 TeV (design: 14 TeV).
The total energy of all protons in the beams together is about 600 MJ.

The energy per proton is limited by the magnetic field strength and the curvature radius. Increasing the radius would need a new tunnel (and a completely new accelerator), increasing the magnetic field strength would need very challenging magnet designs.
