Limits RegistryCERN's Large Hadron Collider accelerated proton beams to 6.8 TeV per beam during Run 3 operations beginning in 2022, giving a 13.6 TeV center-of-mass collision energy — the highest beam energy ever achieved in a laboratory accelerator. The LHC reached 6.5 TeV per beam in earlier runs before the Run 3 energy increase.
The question, scope, and sources behind this Registry record.
CERN's Large Hadron Collider accelerated proton beams to 6.8 TeV per beam during Run 3 operations beginning in 2022, giving a 13.6 TeV center-of-mass collision energy — the highest beam energy ever achieved in a laboratory accelerator. The LHC reached 6.5 TeV per beam in earlier runs before the Run 3 energy increase.
The highest energy achieved for a single proton beam circulating in a man-made particle accelerator, measured per beam (not center-of-mass).
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
