It doesn't look like there is going to be a big media thing like last year when the LHC initially started up, But Claire arrived at CERN yesterday and has told me that things are moving very fast and everyone is running around getting things sorted.

Access to the tube should be officially closed now, which is in indication that beam start up should be very soon. The exact time is not known yet (at least not by me :D ) But the ATLAS group are expecting Beam splash events on Friday. As soon as Claire knows I'm sure she will let me know and I'll post the details here.

The latest news can be found here: http://lhc-commissioning.web.cern.ch/lhc-commissioning/news/LHC-latest-news.htm

Beam status website: http://op-webtools.web.cern.ch/op-webtools/vistar/vistars.php?usr=LHC1

And lastly, quasi-live event displays will be selected by a dedicated group of people and posted here:http://atlas.web.cern.ch/Atlas/public/EVTDISPLAY/events.html
 
Latest news from the control room is it looks like we'll get beam splash at 11pm on friday evening (that's midnight SA time).

Officially, it takes 13 days after that for collisions... but it could be sooner :)
 
Lovely .... So we just get reasonably priced uncapped ADSL in SA, and now its all going to dissapear into a big black hole!!... Maybe there will be another disruption from the "Future" ... hehe
 
Nope. A future-time particle event will prevent it. I foresee a banana peel getting involved this time.

Brilliant :)

So when do we start getting black holes?

2 January 2010, which will cause another near-fatal catastrophy.

Then they sort that out over the next couple of months and ramp up the power a bit and by 14 May unstable black holes occur.

Then they take another couple of months to calculate that these black holes are safe.

By 20 December 2012 an unknown (15 yr old?) scientist will anounce that they got their calculations wrong and that the very first black hole, made years ago, was activated by the earth's core and is on it's way through middle-earth, where it devoured the entire contents of the core making it huge.

This makes it perfectly in time for...another 2012 disaster movie.:D

Would've been funny if it wasn't so likely to happen. Nothing would surprise me at this time.

How can the people who work there not go mad with anticipation? I don't think I'd have the stomach to work on a project like this...assuming I had the brains.:o
 
hehe, nah, unfortunately nothing as exciting as all that.

Here's a good read on what can happen with mini black holes at the LHC:
http://backreaction.blogspot.com/2008/04/black-holes-at-lhc-what-can-happen.html

For those of you who don't want to read it all, the cliff notes version says:

"If tiny black holes were produced because large extra dimensions did exist in the necessary number with the necessary radius, and if they did not evaporate within 10^-26 seconds as expected (Hawking evaporation is considered a very robust prediction, so this scenario is not confirmed by well founded theories), most of them would have such a high velocity that they escape the gravitational field of the Earth for good. Even if they travel straight through the centre of the Earth, the few nucleons they can hit wouldn't change their momentum in an appreciable way."

... ie, the mini black hole would "eat" less than 1 heavy atom before escaping the earth for good. Sorry :(

damn:D
 
I would have watched your movie M00ey. I've watched all the other doomsday movies so why wouldn't I have watched yours. :o
 
So far the detector has been stopped by, two lager bottles, a chunk of bread, bad soldering. What have a missed?

Anyone want to take bets on what's next. The banana peel is a maybe, But I think the above combination is missing some Swizz cheese?

Maybe it was hungry. We all need food :)

Na, they stopped the janitor eating his lunch in the tunnel. :o

There is beam :)

Set it to stun and aim it at that Klingon vessel number one. :p
