Almost looks like the tool was traversed back over the work rapidly after the finishing cut was made. Bryan may be right though, could be ground. Without getting a real look and touch of it its hard to tell. Anyone know of anybody who has been to Cern lately who might know?

LHC Detectors.. The CMS detector
The CMS ( compact muon solenoid) detector is one of the 4 main experiments running on the LHC (large hadron collider )
The size and complexity of these instruments is mind boggling.. the main component of the detector is a VERY strong electromagnet it uses superconducting niobium-titanium coils
The detector is 100 m underground, and above the main shaft leading to the underground cavern is a very slick overhead gantry crane, they also have a large picture of the detector hanging from the roof. The big yellow assemblies in the background are support structures used for lowering parts of the detector down the 100M shaft.

Underground the detector cavern is the size of a cathedral.. we mistakenly joined a French speaking group for the underground tour...

The detector generates vast amounts of data when running, Just the silicon pixel trackers alone have 66M channels of data.
I wonder why these two computers have flouro stripes? A small portion of the underground electronics.

The CMS and ATLAS detectors were jointly responsible for identifying what is believed to be the Higgs Boson. I've yet to find out how that helps time-travel

Thanks again for the pictures Ray. I believe I saw parts of the CMS lowered into place in a doco, the hole isnt much bigger than some of the parts. Tricky at the end of 100m of cable they say.
I'm sure I had one somewhere, maybe I vacced it up.
Ok stupid question time. Now maybe its a little Nobel laureate humour but why do they put "compact" in front of something that weighs 14k tons? or something else that's going to be 50kms long?
I guess they have plans for a bigger one?

I was wondering something similar, a 14,000 tonne superconducting niobium titanium electromagnet drawing 18,000 Amps deserves a better name than "solenoid" ...
Here are a few pictures of the computing center, the real time display shows data transfers to other LHC collaborating institutions around the world, typical data transfer rates are in the 10 Gigabit range.. they have multiple dedicated fibre connections into the various Tier 1 computing centers ( CERN is a Tier 0 center )

This is the NEXT computer that was the world's first web server, Tim Berners-Lee put up the proposal to develop HTML and ( the web) but he was refused permission, then he was given the job to evaluate a NEXT computers for CERN internal use, he evaluated it by writing a web server ( the world's first ) and thus he gets credit for creating the world wide web...
IMG_0287s.JPG
The computing center has around 10,000 servers with 90,000 cpu cores, and handles a petabyte of data per day..

For those that are interested in the nitty gritty of building an accelerator here is a useful resource: Fermilab Technical Division Drafting Images Database.

lols
69 was also the earliest serial i noticed as well.
Yeah FermiLab is an accelerator in the US, run by the "US Atomic energy commission" now known as "US Department Of Energy"
FermiLab is a big collaborator with CERN and the LHC, I saw their equipment all over the place along side stuff from KEK (Japan). One thing i thought was interesting was all the drawings for the SSC (Superconducting Super Collider) that was canned in '93 after spending $2bil, if it was ever finished it would have been 3.5 time more energetic than the LHC, alas it was destined only to become the most expensive hole in history.

PS. if you do a search for CERN or LHC etc you will find metric drawings.

I recall reading about a collider that the Americans canned. The article went on to say that it was most likely the last opportunity for them as the cost would be too probibitive even for good ol' USA in the future. Who knows. Looking at their current economy it does seem unlikely. They are finding it hard to pay the electric light bill.
I also read a letter in the Adelaide Advertiser from a person who claimed that the whole Cern busines and the Higgs Boson discovery was a complete waste of time and money and that there was no benefit from the research.
Some people have little imagination. How much has space exploration cost and how many of our modern inovations stem from that. One of the reasons I like this forum is that there are a lot of people here who think about things rather than spout what they heard from their mates etc. Logic is a foreign word to them and has no place in their lives. I am constantly amazed to find grown adults who cannot do even simple math functions like area of a circle etc. They can generally keep count of the score for their footy team tho!
