All Quiet on the ATLAS front

After a fantastic start-up and following days, the LHC hit a teething problem when a power transformer blew at point 8. As a result, beam could not do full circuits and ATLAS has seen no beam since 12th September, but before that they had the beams circulating for lengthy periods, and had hoped for collisions this Thursday.
The power transformer has now been repaired using a spare from the CMS. The last sector is due back on Wednesday morning, at which point LHC comes out of the commissioning mode. I would guess that we will not see collisions before the weekend, but we have had such good progress in the last 10 days, who knows?!
