In summary, the Large Hadron Collider will not be able to perform a low-energy "engineering run" in November as originally planned due to a failure of a Fermilab-built magnet during high-pressure tests in March. This delay means that operators will not have a chance to gain experience with the particle accelerator's systems before high-energy runs begin in spring next year. The attempt to quickly reach full energy in 2008 led to the magnet accident, causing a one-year delay.

The Large Hadron Collider will not be ready in time to perform a low-energy "engineering run", which was originally scheduled to take place this November, according to an official at CERN. This will leave the operators no chance to gain experience with the particle accelerator's steering and detection systems before the high-energy runs begin in spring next year. The delay is due primarily to the failure of a Fermilab-built magnet during high-pressure tests in March.

The attempt to reach the full energy quickly lead to the magnet accident in 2008, leading to a delay of one year.
That doesn't mean it couldn't have happened with more time at lower energy, but it would have given more time to find the problem.
 

1. What is the LHC and why is it important?

The LHC (Large Hadron Collider) is a particle accelerator located at CERN in Switzerland. It is the world's largest and most powerful particle collider, used by scientists to study the fundamental building blocks of the universe and to replicate the conditions that existed just after the Big Bang. Its research has led to groundbreaking discoveries and advancements in our understanding of particle physics.

2. Why is the LHC skipping low-energy test runs?

The LHC is skipping low-energy test runs in order to save time and resources. Low-energy test runs are used to gradually increase the energy of the particle beams, but they can take several weeks to complete. By skipping these runs, the LHC can reach higher energy levels faster and begin conducting experiments sooner.

3. Will skipping low-energy test runs affect the accuracy of the experiments?

No, skipping low-energy test runs will not affect the accuracy of the experiments. The particle beams will still be carefully monitored and calibrated to ensure accurate results. In fact, by reaching higher energy levels faster, the LHC may be able to produce more precise data.

4. Are there any risks involved in skipping low-energy test runs?

The LHC has been extensively tested and safety protocols are in place to prevent any potential risks. Skipping low-energy test runs does not pose any significant risks, as the particle beams will still be controlled and monitored at all times.

5. When will the LHC start conducting experiments at high energies?

The LHC is expected to start conducting experiments at high energies in April 2022. This is when the LHC will reach its maximum energy level of 14 TeV (teraelectronvolts) and scientists will be able to collect data from these experiments.
