(Two months to change a part) reminds me of my auto dealer..:-)

I guess this is the curse of cryogenic experiments. Exchanging the part itself will take a few hours but cooling down the stuff again to near abs-zero is nothing you can do in a few days. I think this also was a great impediment for the research with cryogenic resonant masses gravitational wave detectors and helped to convince many that interferometry is the way to go in GW detection (so you get better sensitivity AND better duty cycle).

It's a sad setback for LHC, both scientifically and financially. But let's not forget that compared to the failed SSC, the LHC comes at a bargain price :-)

6 billion dollars?

CERN says total cost is 6.03 billion Swiss Francs

Yup! At the time SSC was killed, the projected cost was $12 billion (!!).

Isn't that equivalent to 1 Bill Gates dollar? So what's the problem, just let Uncle Bill pay for it!

We need the SSC. You all into armadillos? :)

Play a game and perhaps learn

Play a game and perhaps learn a little... the LHC Game

Play a scientist working in the LHC's control room. You have to control and fine tune the equipment before you can fire up the LHC. You can't proceed to the next stage until you have successfully completed the work you are assigned.
