I just started a new events and discussion thread.

The old one is at viewtopic.php?f=4&t=359

Clearing the slate for the upcoming first collisions

Thought it would be nice to have these links up high on this thread, let the games begin!

It better work at 9:00 AM CERN time as they have live satellite feed booked http://press.web.cern.ch/press/lhc-firs ... /schedule/ lol

Uh oh Unexpected 7 hour down time for cryo cold compressor failure in sector 23. Hopefully they can deal with some other issues that require access during the delay.

I mentioned to a high up in Beams at CERN if the pressure was more intense then usall.. I actually did not get a response.. Guess he was a tad busy..

Its gotta be intense..

You know tho.... Remember last year.. These guys are good at this.

It does seem murphy has been a bit at play recently. But I think it will work out great...

I do want to watch this live. We need to get live feed info as soon as possible for everybody to tune in via computer and via TV as well..

Its gonna be a crazy day in chat thats for sure.

More emergency dumps, but they seem to take it in stride:

beams lost...
starting ramp down and precycle ...
then will inject again

They wouldn't have gotten this far if they gave up easily!

Oh bugger, I de-announced this topic >_<

Hopefully Chris will save my bacon soon

We need some time window for tuesday's events...

Anyone know the plans ?

We are stuck with ALICE, no way to contact the ALICE ControlRoom. We don't have yet the injection permit because of ALICE. Physics coordinator contacted to unblock the situation.

If these delays haven't taught everyone at Cern patience, nothing will!

Hoping for some nice, stable up-time, like about a year's worth, without problems.

hehehehe....

this does seem pretty funny... I wonder what the story was..

Late night, not much sleep, someone fell asleep ?

You would think that someone would go over there.. Call security over there and have them go wake them up.

Normally the LHC teams do not work to a scheduled moment it seems. They have a set of tasks and get stuff done as things get done. BUT now we have a exact moment where everything must be ready. 9AM on the 30th. The world will be watching live. Thats got to be some pressure

Must be really hard for the experiments as no collisions have occurred at all for a test this year.

They still need to do a 2X2 ramp as thats the plan for the event. I dont think thats terrible difficult tho.

Well no doubt it should be fine. They have been doing lots of 3500GeV ramping and all they gotta do steer the beams to collide. Really wont be that hard I would think..

True there could always be some random cryo failure that might cause delay. Well I am sure everybody has been told the event timing will vary.

So far in the last year the luck has been very good for the LHC team. They have been far ahead of schedule on everything. The minor delays were nothing important.

I have confidence the event will go as planned on time. On Tuesday the news will carry the LHC startup as a headline news story. Maybe even CNN might switch to a live feed during the moments of the event.. The ensuing masses that will hit the net looking up LHC info will find their way here and we will have a record number of visitors.

Its gonna be GREAT FUN in chat too...

Just in from CERN

The interesting thing about this is that its avaliable in HD all the way to 1080P

I hope we see more HD from CERN..

Just in case someone wonders why the time seems to be 1 hour off at CERN: (most of) Europe has switched to Daylight Savings Time this weekend.
