I just started a new discussion thread...
The older one on the events of the weekend is at
viewtopic.php?f=4&t=129
So the LHC is about to start up again after a minor Cryo delay of some hours lenght...
Im not sure what the plans are to do with it on these runs.

Looks like more of the same is planned overnight, collisons for the experiments.
Tomorrow testing for higher intensities and perhaps some ramping.
Interesting to see the intensity scale has been changed on the graph on the status op page.

Well they were overshooting it rather impressively. I liked reporting "Off the charts !"...

It might just be me, but it looks like they locked down the live webcast from the ATLAS control room. I sort of thought they would, given that it says it's for collaboration members only. Still, anyone else able to get in?

does look that way !
BUT... might not be too.. We shall see. Sometimes the computers get wacky.. Ive seen that before..
I know ATLAS has said they will provide access to the public to the live feed. Patience. Notice from their main site they have a link that does not work yet for this very purpose. It will patience..
I understand they are working right now on other things like a blog to be ready for this weekend. Might be this work knocked offline the system we were using..

Interestingly,,, my computer that was already running the live feed is still connected and running it... Of course this will only last so long... BUT im not touching that computer as it might loose it..

Looks like very stable beams. For quite a while too...

Logs say Bucket timing is off by 83 and I see beam 2 intensity falling fairly quick, in fact beam 2 started 30e10 higher then beam 1 now is 30e10 lower. Beam 1 is staying the level. I think a dump will be soon.

Ya, the logs just reported B2 was down to 2 hours and they are ready to dump anytime.

So looks like they are tuning up for 1.1TeV collisions this next weekend according the the schedule.. That will be fun... Hopefully it will be with 4 bunches

If that's true I'll be awake the whole night this time.

THIS weekend according to
http://lhc-commissioning.web.cern.ch/lh ... C-news.htm
Notice the "collisions" without a number... This is them being sneaky I do believe.. The 1.1 studies would lead up to collisions of course
