Brian Cox explains in this 3 minute talk from Feb 2009 what went wrong at CERN last year, and why continuing this work, despite setbacks, is worth it.
It has been over a year since that accident, and many repairs and improvements have been made including:
- Replacing 53 magnets (out of 9,000)
- Installing extra pressure relief valves
- Installing monitors to ensure this can’t happen again
This has made me more confident, but at the same time, the problem we hit happened just after one week of running – maybe there are problems we would have hit only after a few weeks of running, or a few months?
We don’t know everything that might happen, so I’m glad we are playing it safer this time.
