Good job! Title might want to adjust so people can get to it easier. PS: A collegue of mine worked on ATLAS I believe in New Mexico?

Nice pic of the pit, Reminds me of SLD AT SLAC. Time to bring the Mark detector over? It was built torched and all, assembled in Japan, then unassembled and transported by barge into SF Bay then shipped by truck down 280 to Slac, Then Reassembled retorched moved 90 degrees in the pit after assembly, in the pit of SLC then was again commissioned and operated in the 90's, now just sits there in building 752.

Good! I don't understand half of what I just translated but I definately prefer this article to the one yesterday on the music video. Mithridates 17:30, 24 November 2005 (UTC)
Looks like when they were renovating Grand Central Terminal...
1. Nice to see black holes are discussed. It is a topic of Science Fiction as a great mass that automatically sucks all matter near it into it. In fact, any star that becomes a black hole cannot have more mass than that star had, and still has the same orbital properties due to the same mass, but it would be smaller with an event horizon where light cannot escape. This means, you can orbit a black hole like a planet and be safe, except for possible radiation hazards.
2. So, should a particle accelerator produce black hole effects due to the Universe have several dimensions, they will not be a hazard to anyone, and in Science Fiction it would have the Earth sucked up into a miniature black hole.
3. The fun part, is the physics people start having pet black hole projects.
Sorry, folks: feature articles make a particularly tempting target for the vandals, I guess. I've blocked the relevant IP, but he (I'm sure it's a fourteen-year-old boy, or possibly younger) may return from a friend's house, or from school, and so I've protected the article. Let's give it a day or so. DS 13:27, 25 November 2005 (UTC)
We appear to have two conflicting sources of the year the cyclotron was invented.
Source 1: 1931 - Nobel prize website [1] Source 2: 1929 -Lawrence Berkley National Laboratory website [2]
Then there are several other sources that list the year as 1930. While searching through a list of reference, however, I found that the majority of dates point towards 1929, such as the Nobel prize website which also appears to be more of a reliable source (in my opinion) therefore I feel we should stick with the 1929.
Other examples of 1929: [3] [4]
Looking further, into the last link I gave, it appears that while the cyclotron was invented in 1929 but was not actually put into production until 1930, which is probably where the discrepancies in the dates come from.
Also, according to PBS.com [5], it further explains that in 1929 Lawrence already had the idea for the cyclotron in 1929, had the go ahead to build it in 1930, and had a working one in 1931. Therefore I will edit the page to somehow include all three of these dates. Cowman Talk 20:19, 28 November 2005 (UTC)
Bunchofgrapes asked me to review these changes, which he reverted. They were obviously made by someone knowledgable, so I would like to explain why I am not readding any of them:
Please respond here if there are any more questions about the content. Thanks. -- SCZenz 19:45, 1 December 2005 (UTC)
Is that acronym still in use? I can find it nowhere on any atlas sites, and I tought it was more or less dropped as a bit silly.
Great article! May I suggest you the use of a full detector image? Many people don't have an idea on how all this parts are bound together. Check for example http://atlas.ch/atlas_photos/fulldetector/fulldetector.html
At the Compact Muon Solenoid I uploaded some images for example a full detector figure. Dave Barney, who is the leader of the CMS outreach group write me, that we can use it. See: commons:Large Hadron Collider. It would be good, if the ATLAS images would be free as well. -- Harp 10:26, 20 March 2006 (UTC)
At the LEP detectors and the CMS the charged hadrons reached the hadron calorimeter, not only the neutral hadrons and the EM calorimeter stops only the electrons and photons (and perhaphs less energetic charged hadrons). (See the LHC Slice picture at CMS article and the animation you can reach from there.) The article suggests that at the ATLAS the charged hardrons are absorbed in the EM calorimeters. I think it's not so. Could you fix it if I'm right, my English is not perfect. -- Harp 15:19, 22 March 2006 (UTC)
Other: I think about the black hole at ATLAS need a source of information. How much is the possibilite accepted? -- Harp 16:03, 22 March 2006 (UTC)
The EM cal angular resolution is actually where is the pseudorapidity (not ). See http://www.cern.ch/Atlas/GROUPS/PHYSICS/TDR/physics_tdr/printout/Volume_I.pdf page 13. Rotiro 06:26, 4 April 2006 (UTC)
This article states "The construction is scheduled to be completed in June, 2007.", does anyone know the current schedule for completion? I presume it's been delayed and not online yet. 58.161.49.182 14:13, 19 July 2007 (UTC)
I had always been under the impression that particle physics experiments required vacuum in which to operate. If that is true, does CERN anticipate pumping out the entire ATLAS chamber?! Looking at the picture of ATLAS posted on [ APOD] on 2008-02-25, that looks like a pretty huge space to have to reduce to vacuum! dafydd ( talk) 16:28, 25 February 2008 (UTC)
I made http://www.youtube.com/watch?v=kVrUR_SOykk from the images captured by the atlas eye. Seeing it "grow" fascinates me, almost as good as visiting it, maybe even better since the cavern has been very full for a while now. Would it be appropriate to link to it in the "External links" section? I made it to show some friends how huge atlas is. Not sure about the licensing of the images? — betatim 17:06, 20 August 2008 (UTC)
This article is very well written and contains valuable information. Much better than what I have read in many PhD theses and on the official ATLAS website. The only thing I dislike, is the emphasis which has been given to the groups which have developed the transition radiaton detector used for tracking in the inner detector. If you have a look on publications of the ATLAS collaboration, you will see a list of thousands of individuals originating from hundreds of different institutes. So instead of focusing on the involved institutes for a single part of the ATLAS experiment, a new category should be introduced which names alls institutes and their contribution. The according information should be removed from the main text, which would also help to have a clear structure which is easy to read.
May I add that this section is incomplete, incorrect and contains ill defined statements. TIn my opinion it should be removed. —Preceding unsigned comment added by 128.141.84.28 ( talk) 15:31, 27 May 2010 (UTC)
Congratulations, editors - this is an excellent article. It is accessible to readers of just about all levels. The background and history sections are readable by almost anyone and then it gets more and more into the physics. Bubba73 You talkin' to me? 23:20, 14 August 2014 (UTC)
Hi, a sonification of Higgs candidate events was just uploaded (I'm embedding it here). A detailed description is at User:Cas ssc/sandbox. Perhaps we can find a way to insert it here or in some related articles? -- Daniel Mietchen ( talk) 21:41, 21 June 2017 (UTC)
This article refers to the ATLAS experiment, but in the second section ATLAS is described as follows:
"ATLAS is 46 meters long, 25 meters in diameter, and weighs about 7,000 tonnes; it contains some 3000 km of cable. The experiment is a collaboration involving roughly 3,000 physicists from over 175 institutions in 38 countries."
To me, this seems a bit precise, since the first sentence is definitely a description of a detector, a mechanical object while the second sentence describes something more vague, an "experiment" or a "collaboration".
So which is it? Is ATLAS both an experiment and a detector? Can someone clarify this for me? — Preceding unsigned comment added by 128.141.46.236 ( talk) 08:04, 12 August 2017 (UTC)
What has it found? Apart from a brief mention of the Higgs hidden away under "Experimental program," apparently nothing. But there's at least one other thing that I stumbled across just now, and presumably other stuff besides. It would be nice if some knowledgeable person could update the article. 79.64.186.66 ( talk) 08:48, 6 December 2021 (UTC)
