Sure, perhaps Im over-enthusistic about it, but it helps keep me motivated.
I meant the SixTrack work, which as I understood it (perhaps Im wrong!) was running simulations on the particle beams to help Cern model how to calibrate the machine for both the initial and second phase.
Ah I see where the misunderstanding comes from :)
Calibrating the machine is not the construction of the machine. This is a phase that happens when everything is ready and when one needs to be sure detectors are well aligned, that the beam is under control, etc...
