Yesterday's press release from CERN shows hope for restarting the Large Hadron Collider with more modest initial goals. The project involves the largest and most complicated machine ever created by man. The team consisting of thousands of engineers and scientists working together world-wide was frustrated on initial startup last year.
CERN is hopeful that the new startup will yield trouble free operation and information. Because the machine is so complicated even a small failure like a cold solder joint could have a daisy-chain effect forcing more delays. The use of 'super conductors' has forced the engineers to break new technological barriers before any new science can be discovered.
Since billions of dollars have been invested many are watching the progress of this machine, which could hit a 'home run' for theoretical physics unlocking the mysteries of the hidden quantum world.

(Press Release) LHC to
run at 3.5 TeV for early part of 2009-2010 run rising later

The latest tests looked at the resistance of the copper stabilizer. Many
copper connections showing anomalously high resistance have been
repaired already, and the tests on the final two sectors, which
concluded last week, have revealed no more outliers. This means that no
more repairs are necessary for safe running this year and next.
“The LHC is a much better understood machine than it was a year ago,” said Heuer. “We can look forward with confidence and excitement to a good run through the winter and into next year.”
The procedure for the 2009 start-up will be to inject and capture beams in each direction, take collision data for a few shifts at the injection energy, and then commission the ramp to higher energy. The first high-energy data should be collected a few weeks after the first beam of 2009 is injected. The LHC will run at 3.5 TeV per beam until a significant data sample has been collected and the operations team has gained experience in running the machine. Thereafter, with the benefit of that experience, the energy will be taken towards 5 TeV per beam. At the end of 2010, the LHC will be run with lead ions for the first time. After that, the LHC will shut down and work will begin on moving the machine towards 7 TeV per beam.
