Well, its started and the only black hole to be around is my dogs stomach!!!

Woot! Still alive! Did enjoy blasting Valkyries to the dismay of my housemates though!

OK I need tickets to Cuba. Any offers?
Right guys, here is one of the first beam events!
Awesome!

Glad to see it's up and running fine mate! You should change your system specs to the specs of that beast of a machine!

LoL...good call... Fraz's System: CERN LHC

This all looks fantastically interesting but would like an explanation to go with it all...
Fraz mate, can you possibly put in laymans terms exactly what that is showing us? I'm certainly intruiged by all of this but never really understood it. Be interesting to hear what is being made of that as at the min it looks like a cool blue explosion in a tube!!!!

Ok, so you have a wire frame representation of the entire detector. The cylindrical bit in the centre is the silicon tracker, which is not being read-out right now (otherwise you'd see tracks going through it).
Just outside this cylinder is where you see the base of all the big blue bars. These bars represent the size of the energy deposits in the calorimeters. Importantly - and confusingly - these blue bars do not represent the direction of travel of the particles... if this was a two-beam collision right in the centre of the detector then they would. But calorimeters only give you an energy readout, not a direction, and the collisions are not happening in the usual place right now.
Other than these blue bars, there are a few green bits here and there. These are muon detector stations providing hit information in the outer parts of the detector. Unfortunately it looks like a lot of the detector is not active right now (or the event display person disabled certain elements of the visualisation), otherwise this image would look a lot more complicated.
At the moment the beam is not under very tight control... so the beam is probably exiting the beam pipe or colliding with the edges of it, or possibly hitting some remnant gas atoms inside the beam pipe itself. This then causes a whole bunch of particles to spew into one end of the detector where they get absorbed in the calorimeters (and give you that slightly misleading impression of where the particles are coming from). If the tracker was switched on, you'd be able to see which direction the particles were actually coming from. Hopefully we'll have it on later. I'll post up the event displays as they come
Here is another:
This event is a real mess. The red lines are supposed to reconstructed muon tracks I think, but the strangeness of these single beam events is confusing the software. It also looks like there is a cosmic muon coming down through the detector from the top right of the image.
Ah - just found this regularly updated e-commentary page:

It's running a bit slow though...
That would be cool mate
Just remember to let us know what you are seeing when putting images up so we can understand
feels like a bit of an anti-climax, like ive driven miles to the bunny ranch, only to discover im impotent.
That is very cool. I love the idea that all these strange particles are passing through us and the earth all the time.
I think it's really sad that the general public have picked up on the "end of the world" aspect rather than the science. although atleast the media has put out some reasonably good articles about this project. I like this site that gives you the important info.http://www.hasthelhcdestroyedtheearth.com/
