I lately added some material to the page, which I think is all more or less common knowledge among particle physics folks, but with no references beyond a link to the AGS page. Since there is no question in my mind that the material is substantially factually correct and does add content, I wonder if is this useful or proper, vs the alternatives of missing or wrong (eg, it was previously said to be an electron accelerator) information? I am new to editing Wiki, and still a bit vague on such things. Also, practically speaking, tracking down a full set of references is more than I can typically undertake, unfortunately.
Also, with the information added, I wonder if the page qualifies to be a level up from just a stub? I'm not sure just how to do this (I do see what looks like the place, as "particle-stub", in double braces), and if that is something I should do. Thanks Wwheaton 19:02, 20 August 2007 (UTC)
The kinetic energy needed is considerably larger than the mass of the antiproton, due to the requirement to conserve both momentum and energy, since the products cannot be produced at rest. On the other hand, in collisions with multi-nucleon nuclei, considerable advantage may be taken from the fact that the nucleons bound in nuclei are in motion, with energies up to about 7 MeV. A more accurate threshold, commonly cited, is 6.2 GeV. Wwheaton ( talk) 03:33, 1 June 2008 (UTC)
A red link has been twice inserted into this article by User:79.166.105.190, claiming invention by Georgios Giolvas. Two references are given, but both are in Greek. I am reverting the change again, until (a) references can be given in English (this is the English Wikipedia, after all) and (b) at least a reliably sourced stub article about Georgios Giolvas can be provided. I know nothing about the factual basis of this claim and am not denying its possible accuracy, but we must have better support that that given so far.

Here is an article in Italian Wikipedia about Georgios Gkiolvas (Greek physicist, engineer, inventor 1920 - 2003. Correct spelling: "Gkiolvas", could also be found as "Ghiolvas" or "Giolvas") mentioning Bevatron [1]. The act of Gkiolvas used to be underground according to its nature (mainly creating military equipment) so there are not any formal documents available on the internet proving his inventions. However, there are many books (in Greek language) written by modern researchers and scientists (such as George Palmos, Anestis Keramydas, Nicolaos Pappas, Ntorepa Pepa, Kalogeropoulos and more...) mentioning Gkiolvas as the initial designer/inventor of Bevatron among other inventions such as anti-aircraft Artemis 30, Ultralow Frequencies Sound Cannon [2], G-Ghiolvas System II (NicoPal) [3] and more...
Moreover, there are many references in Greek TV Shows "Oi Pyles Toy Anexigitou (29-09-2007)", "Atheatos Cosmos (19-10-2004)" and "Choris Montaz II (2004)" directed by jurnalist Costas Chardavelas in which various researchers/scientists (many of them known Gkiolvas in personal) admited that G. Gkiolvas invented Bevatron. There are two or three videos (also in Greek language, can be found on youtube) showing Gkiolvas talking about Bevatron Project and admiting that he was the initial designer/inventor of Bevatron. Bevatron's invention by Georgios Giolvas is also confirmed by his widow Aikaterini Aksari.
There are also very serious clues of the existence of a proposal document (dated between early to mid 50's) in which Georgios Gkiolvas presents Bevatron design to Greek Department of Defense and after their rejection; Gkiolvas "sells" Bevatron's design to US scientists.
I understand that the article cannot be changed without any English reference or formal evidences/documents, things which unfortunately I cannot provide right now. If someone can post such evidences or at least translate some of them in English language, I would be grateful. Thank you and please accept my apologies for the inconvenience. —Preceding unsigned comment added by 79.166.105.190 ( talk) 22:46, 29 April 2009 (UTC)
I’ll try to gather as many sources and references as I can. As far as I know, Gkiolvas was on LBL that time, if I’m not mistaken there are some photos showing him among other scientists. Please blame my poor English for confusing the terms invented and designed. I’m not quite sure of the dates of the photos or the documents mention earlier. I’ll try to find English references or at least translate some of them in English. I’ll post any future material here. Thanks in advance. —Preceding unsigned comment added by 79.166.108.230 ( talk) 12:51, 30 April 2009 (UTC)
I got here through from the Bevalac redirect. First time I hear this name, but if it was in use (or still is), it should probably be mentioned in the article IMO. Headbomb { ταλκ κοντριβς – WP Physics} 01:15, 12 May 2009 (UTC)
Does anyone have an idea how to get permissions for the pix here, or in here? The former is interesting (& kind of sad, being of the Grand Old Girl at the end of her life), while the pix in the Lofgren pdf are especially useful. I think the one on p.12 should really go as the lead, showing it just completed in all its naked glory, and the one on p.13, nearing completion, is very good too. My guess is that these latter ones in the Lofgren talk are almost certainly out of copyright, or made as US Government work and thus in public domain, but I can't prove it and I am ignorant of these intellectual property issues on Wikipedia (and I also don't know how to extract a good photo from a pdf). Thanks... Wwheaton ( talk) 18:05, 17 January 2010 (UTC)
I don't see any reason for the "out of date" tag. Nothing new has happened with the accelerator in quite some time, after all. Removing. PianoDan ( talk) 02:15, 28 January 2015 (UTC)
Any history of Bevatron fires or other accidents? 2601:1C2:4100:FD60:CDDC:AE28:E38:15C8 ( talk) 04:09, 25 March 2023 (UTC)
