OY! Power Fail In meyrin.

Post by Harbles » Wed Dec 02, 2009 2:12 am

About 8PM EST or 2AM CERN time a 18 KV power system failed cutting power to 6 sectors of CRYO and Magnet power converter systems. The Page one sait they would report back about now but their web servers don't work. However the LHCB log page still functions.
Last year a week or so before the unfortunate events with the cryo bussbar splice a power transformer failed and had to be replaced.A few weeks ago a 'bird with a baguette' may have caused another hv power feed system fail.
I hope this is not a pattern, that the older infrastructure salvaged from LEP etc is not up to the task.

Thanks for the info!
I am currently on the secondary site (Prevessin) and I was wondering why cern servers are not responding anymore...
Well, this answer it.

*Frack* This is happening when I need these servers, of course.

(I have no doubt the machine is not damaged. It is well designed for this kind of things.)
